Question 1Codes and Standards (ASME A17.1/A17.1s, A17.2, A17.3, A17.4, A17.5, A17.6, A18.1)

Under ASME A17.1/CSA B44, what is the minimum required vertical clearance above the top of the car crosshead when the car is at its highest stopping position in a typical overhead arrangement?

  1. 12 inches (305 mm)
  2. 18 inches (457 mm) Correct answer.
  3. 24 inches (610 mm)
  4. 6 inches (152 mm)

Explanation

A17.1 sets a minimum refuge clearance of 18 inches (457 mm) above the car crosshead, measured with the car at its highest stopping position, to protect personnel riding on top of the car. Greater clearances are required where the car top is used as a work platform or where the overhead sheave arrangement demands it.

Question 2Codes and Standards (ASME A17.1/A17.1s, A17.2, A17.3, A17.4, A17.5, A17.6, A18.1)

ASME A17.2 inspection of a traction elevator's suspension means includes verifying that the ropes are free from which condition that mandates immediate replacement regardless of remaining life calculations?

  1. Broken wires exceeding the replacement criteria for the rope construction Correct answer.
  2. Normal rope lay markings from the manufacturer
  3. Uniform light surface oxidation
  4. Slight elongation within the rope's elastic range

Explanation

A17.2 requires the inspector to count broken wires over a specified length and compare against the replacement criteria for the specific rope construction and lay. Exceeding those criteria condemns the rope. Surface oxidation, lay markings, and elastic elongation are normal and are not grounds for replacement.

Question 3Codes and Standards (ASME A17.1/A17.1s, A17.2, A17.3, A17.4, A17.5, A17.6, A18.1)

According to ASME A17.1/CSA B44, the clearance between the hoistway door and the car door or car door jamb, measured where a person could be exposed, must be limited to prevent which specific hazard?

  1. Light infiltration into the car
  2. Finger entrapment between door panels
  3. A person reaching through the gap and being carried into the hoistway Correct answer.
  4. Air pressure differential between car and landing

Explanation

The gap limitation addresses the hazard of a passenger inserting a hand or arm between the car and hoistway doors and being pulled into the hoistway as the car moves. A17.1 limits this clearance to a dimension that prevents a person from reaching through to the hoistway side.

Question 4Codes and Standards (ASME A17.1/A17.1s, A17.2, A17.3, A17.4, A17.5, A17.6, A18.1)

Which ASME standard governs the inspection, testing, and maintenance of existing elevators and is the reference for periodic Category 1 and Category 5 tests?

  1. ASME A17.1/CSA B44
  2. ASME A17.2 Correct answer.
  3. ASME A18.1
  4. ASME A17.3

Explanation

A17.2 is the inspection and test standard that defines the frequency and procedures for periodic inspections and tests, including Category 1 and Category 5 tests. A17.1 covers new installations, A17.3 covers existing installation upgrades, and A18.1 covers platform lifts.

Question 5Codes and Standards (ASME A17.1/A17.1s, A17.2, A17.3, A17.4, A17.5, A17.6, A18.1)

A Category 5 test under ASME A17.2 is required at what maximum interval for a traction elevator?

  1. Every 6 months
  2. Every 5 years Correct answer.
  3. Every 3 years
  4. Every 12 months

Explanation

Category 5 tests, which include rated load and safety device tests, are performed at intervals not exceeding five years. Category 1 tests are performed annually. The five-year interval reflects the more invasive and load-intensive nature of the Category 5 procedure.

Question 6Codes and Standards (ASME A17.1/A17.1s, A17.2, A17.3, A17.4, A17.5, A17.6, A18.1)

ASME A17.3 addresses which aspect of elevator safety?

  1. Certification of elevator inspectors
  2. Design of new escalators
  3. Manufacture of hydraulic power units
  4. Minimum safety requirements for existing elevators and escalators Correct answer.

Explanation

A17.3 establishes minimum safety requirements for existing elevators and escalators, providing a baseline for upgrading older equipment that predates current A17.1 requirements. It is distinct from A17.1, which governs new installations.

Question 7Codes and Standards (ASME A17.1/A17.1s, A17.2, A17.3, A17.4, A17.5, A17.6, A18.1)

Under ASME A17.1/CSA B44, the governor tripping speed for a car safety device must be at least what percentage above the rated speed of the elevator?

  1. 115 percent Correct answer.
  2. 100 percent
  3. 140 percent
  4. 125 percent

Explanation

The governor must trip at a speed at least 115 percent of rated speed so that the safety device engages before the car reaches an unsafe overspeed condition. The exact tripping speed range is also capped by an upper limit to prevent premature or violent engagement.

Question 8Codes and Standards (ASME A17.1/A17.1s, A17.2, A17.3, A17.4, A17.5, A17.6, A18.1)

ASME A17.5 applies to which equipment?

  1. Guide rails and brackets
  2. Counterweight frames
  3. Elevator and escalator electrical equipment Correct answer.
  4. Hydraulic cylinders and plungers

Explanation

A17.5 covers electrical equipment used in elevator and escalator systems, including control panels, drives, and associated electrical components. It provides requirements that complement the electrical provisions of A17.1.

Question 9Codes and Standards (ASME A17.1/A17.1s, A17.2, A17.3, A17.4, A17.5, A17.6, A18.1)

An inspector is evaluating a machine-room-less elevator where the controller is mounted in the hoistway. Under ASME A17.1/CSA B44, which condition must be satisfied for this arrangement?

  1. The controller must be mounted above the car at all times
  2. The controller must be accessible only from the car top
  3. The controller must be located where a person can safely access it and must be protected from moving parts Correct answer.
  4. The controller must be enclosed in a fire-rated cabinet

Explanation

A17.1 permits machinery and control equipment in the hoistway for MRL designs provided it is located where authorized personnel can safely access it and is guarded from moving equipment. Accessibility and protection from moving parts are the governing criteria.

Question 10Codes and Standards (ASME A17.1/A17.1s, A17.2, A17.3, A17.4, A17.5, A17.6, A18.1)

During a Category 1 test on a hydraulic elevator, the inspector observes the car sinking below the landing with the power off. Which component is most directly implicated?

  1. The safety bulkhead
  2. The counterweight sheave
  3. The lowering valve or check valve Correct answer.
  4. The governor

Explanation

Sinking at a landing with power removed points to leakage past the lowering valve or a defective check valve in the hydraulic power unit. A17.2 requires verifying that the car does not sink measurably under these conditions. Governor and safety devices are not involved in holding the car at a landing.

Question 11Codes and Standards (ASME A17.1/A17.1s, A17.2, A17.3, A17.4, A17.5, A17.6, A18.1)

A traction elevator has a rated speed of 500 fpm. According to ASME A17.1/CSA B44, the minimum governor tripping speed must be at least approximately:

  1. 500 fpm
  2. 700 fpm
  3. 575 fpm Correct answer.
  4. 625 fpm

Explanation

The governor must trip at not less than 115 percent of rated speed, so 500 fpm multiplied by 1.15 equals 575 fpm. The upper limit is also bounded to prevent excessive tripping speeds that could damage the car.

Question 12Codes and Standards (ASME A17.1/A17.1s, A17.2, A17.3, A17.4, A17.5, A17.6, A18.1)

Under ASME A17.2, the annual Category 1 test of a traction elevator's car and counterweight safeties includes which action?

  1. Applying the safety with the car at rest and the brake released
  2. Dropping the car from rated speed with rated load
  3. Tripping the safety with the car moving at inspection speed and no load Correct answer.
  4. Testing the safety with the governor removed

Explanation

Category 1 safety testing is performed at inspection speed with no load to verify that the safety mechanism engages and grips the guide rails without the risk of a full-speed drop. The more severe rated-load, rated-speed test is reserved for Category 5.

Question 13Codes and Standards (ASME A17.1/A17.1s, A17.2, A17.3, A17.4, A17.5, A17.6, A18.1)

An escalator is being inspected under ASME A17.1/CSA B44. Which device is required to stop the escalator if a foreign object becomes caught between the skirt panel and the steps?

  1. The skirt obstruction device Correct answer.
  2. The handrail speed monitor
  3. The step demarcation sensor
  4. The combplate impact device

Explanation

The skirt obstruction device (skirt guard switch) detects objects trapped between the skirt panel and the moving steps and stops the escalator. Combplate impact devices address objects caught at the combplate, a different location.

Question 14Codes and Standards (ASME A17.1/A17.1s, A17.2, A17.3, A17.4, A17.5, A17.6, A18.1)

Under ASME A17.1-2019/CSA B44:19, what is the required minimum engagement depth of the hoistway door interlock's locking members before the interlock contacts close?

  1. The locking device must engage at least 7 mm (approximately 0.28 inch) Correct answer.
  2. The locking device must engage at least 1/2 inch
  3. The locking device must engage at least 1 inch
  4. The locking device must engage at least 1/4 inch

Explanation

The interlock contacts may close only after the locking members have engaged by at least 7 mm, approximately 0.28 inch. This ensures that contact closure depends on mechanical engagement of the lock. The specified minimum concerns the depth of locking-member engagement under the stated 2019 edition.

Question 15Codes and Standards (ASME A17.1/A17.1s, A17.2, A17.3, A17.4, A17.5, A17.6, A18.1)

A hydraulic elevator's pressure relief valve is set at 150 percent of full-load pressure. Under ASME A17.1/CSA B44, this setting is:

  1. Too high, because relief valves must be set no higher than 125 percent Correct answer.
  2. Acceptable, because relief valves must be set at 150 percent
  3. Too low, because relief valves must be set at 200 percent
  4. Acceptable only if the system uses a rupture valve

Explanation

A17.1 requires the pressure relief valve to be set to open at no more than 125 percent of the pressure required to lift the rated load, protecting the hydraulic system from overpressure. A 150 percent setting exceeds this limit and must be corrected.

Question 16Codes and Standards (ASME A17.1/A17.1s, A17.2, A17.3, A17.4, A17.5, A17.6, A18.1)

Under ASME A17.2, when must the oil in a hydraulic elevator's tank be sampled and evaluated?

  1. Only when the car fails to level at a landing
  2. Never, because hydraulic oil does not degrade
  3. At intervals specified by the maintenance program, with condition assessed for contamination and viscosity Correct answer.
  4. Only when a visible leak is detected

Explanation

A17.2 requires hydraulic fluid to be checked as part of the maintenance program at specified intervals, assessing contamination, viscosity, and overall condition. Degraded oil affects valve operation, leveling, and system reliability.

Question 17Codes and Standards (ASME A17.1/A17.1s, A17.2, A17.3, A17.4, A17.5, A17.6, A18.1)

Under ASME A17.1/CSA B44, the car enclosure must be designed to support which load on the car top when it serves as a maintenance platform?

  1. A concentrated load of 100 lb at any point
  2. A concentrated load of 500 lb at the center
  3. A load of 300 lb on any 2 square feet Correct answer.
  4. A uniform load of 50 lb per square foot

Explanation

Where the car top is used as a working platform, A17.1 requires it to support a load of 300 lb on any 2 square feet (approximately 1,335 N on 0.19 m²). This ensures the car top can safely support maintenance personnel and their tools.

Question 18Codes and Standards (ASME A17.1/A17.1s, A17.2, A17.3, A17.4, A17.5, A17.6, A18.1)

  1. ASME A17.3 Correct answer.
  2. ASME A17.1/CSA B44
  3. ASME A17.2
  4. ASME A17.6

Explanation

A17.3 establishes minimum safety requirements for existing elevators, including provisions for door interlocks and car movement prevention that older installations may lack. A17.1 applies to new installations, while A17.2 covers inspection and testing.

Question 19Codes and Standards (ASME A17.1/A17.1s, A17.2, A17.3, A17.4, A17.5, A17.6, A18.1)

Under ASME A17.1/CSA B44, the maximum allowable acceleration and deceleration for passenger elevators is generally limited to what value to protect standing passengers?

  1. 2 ft/s²
  2. 8 ft/s²
  3. 4 ft/s² Correct answer.
  4. 6 ft/s²

Explanation

A17.1 limits acceleration and deceleration to approximately 4 ft/s² (about 1.2 m/s²) for passenger comfort and safety, preventing falls and injuries to standing passengers. Higher rates may be permitted only under specific conditions with compensating features.

Question 20Codes and Standards (ASME A17.1/A17.1s, A17.2, A17.3, A17.4, A17.5, A17.6, A18.1)

A door operator on a passenger elevator closes the car door with a kinetic energy exceeding the limits in ASME A17.1/CSA B44. Which device is required to limit the closing force?

  1. A car door interlock
  2. A hoistway door closer spring
  3. A door reopening device with a force-limiting feature Correct answer.
  4. A governor-driven door check

Explanation

Where door closing kinetic energy exceeds the code limits, a reopening device with force limitation is required to prevent injury to passengers. The device reverses the door upon contact and limits the closing force to within the specified maximum.

Question 21Codes and Standards (ASME A17.1/A17.1s, A17.2, A17.3, A17.4, A17.5, A17.6, A18.1)

Under ASME A17.2, a Category 5 test on a traction elevator with a rated speed above 500 fpm requires which safety test condition?

  1. Safety test at no load and inspection speed
  2. Safety test at 125 percent of rated load at rest
  3. Safety test at half load and half speed
  4. Safety test at rated load and rated speed Correct answer.

Explanation

Category 5 testing for higher-speed traction elevators requires the car safety to be tested at rated load and rated speed to verify that the safety stops and holds the loaded car under the most demanding condition. This is a more severe test than the Category 1 no-load inspection-speed test.

Question 22Codes and Standards (ASME A17.1/A17.1s, A17.2, A17.3, A17.4, A17.5, A17.6, A18.1)

An MRL elevator has its traction machine mounted on guide rails within the hoistway. Under ASME A17.1/CSA B44, which requirement applies to the machine's mounting and access?

  1. The machine must be supported independently of the guide rails and accessible from outside the hoistway
  2. The machine must be enclosed in a separate machine room adjacent to the hoistway
  3. The machine must be removable only with the car at the top landing
  4. The machine must be mounted so that it can be safely serviced, with the guide rails designed to carry the machine loads Correct answer.

Explanation

A17.1 permits rail-mounted MRL machines provided the guide rails and their supports are designed for the additional machine loads and the equipment can be safely serviced. The design must account for the combined static and dynamic forces imposed by the machine.

Question 23Codes and Standards (ASME A17.1/A17.1s, A17.2, A17.3, A17.4, A17.5, A17.6, A18.1)

Under ASME A17.1/CSA B44, a plunger for a direct-acting hydraulic elevator must be provided with a stop ring or other means to prevent the plunger from leaving the cylinder. What is the purpose of this requirement?

  1. To prevent the plunger from being projected from the cylinder if the car is obstructed Correct answer.
  2. To center the plunger within the cylinder bore
  3. To reduce packing wear during normal travel
  4. To limit oil temperature rise

Explanation

The stop ring prevents the plunger from being forced completely out of the cylinder when the car is obstructed and pressure builds, which could release the car and cause a fall. It is a critical mechanical safeguard against catastrophic failure.

Question 24Codes and Standards (ASME A17.1/A17.1s, A17.2, A17.3, A17.4, A17.5, A17.6, A18.1)

ASME A17.6 addresses which subject?

  1. Suspension means for elevators, including rope and belt criteria Correct answer.
  2. Hydraulic fluid specifications
  3. Electrical wiring methods in hoistways
  4. Escalator step design

Explanation

A17.6 establishes requirements for elevator suspension means, covering steel wire ropes, coated steel belts, and other suspension systems, including construction, testing, and replacement criteria. It complements the suspension provisions of A17.1.

Question 25Codes and Standards (ASME A17.1/A17.1s, A17.2, A17.3, A17.4, A17.5, A17.6, A18.1)

Under ASME A17.2, the inspector is verifying the buffer stroke on a traction elevator. Which condition indicates the buffer requires adjustment or replacement?

  1. The buffer shows uniform wear on the plunger
  2. The buffer returns to its normal position after compression
  3. The buffer oil level is at the marked line
  4. The buffer stroke is shorter than the designed or marked stroke Correct answer.

Explanation

A17.2 requires the buffer stroke to meet the designed or marked stroke to ensure the buffer can absorb the required energy. A shortened stroke indicates loss of function, often from oil loss or mechanical damage, and must be corrected.

Question 26Codes and Standards (ASME A17.1/A17.1s, A17.2, A17.3, A17.4, A17.5, A17.6, A18.1)

Under ASME A17.1/CSA B44, what is the minimum required clearance between the hoistway door and the door frame or jamb that prevents a 4-inch sphere from passing through when the door is closed?

  1. 2 inches
  2. 3/4 inch
  3. 1 inch
  4. 1/2 inch Correct answer.

Explanation

A17.1 requires that the clearance between the hoistway door and the jamb be limited so a 4-inch diameter sphere cannot pass through the closed door assembly. This keeps a child or adult limb from entering the hoistway gap.

Question 27Codes and Standards (ASME A17.1/A17.1s, A17.2, A17.3, A17.4, A17.5, A17.6, A18.1)

Question 28Codes and Standards (ASME A17.1/A17.1s, A17.2, A17.3, A17.4, A17.5, A17.6, A18.1)

Under ASME A17.1/CSA B44, the clearance between a passenger elevator's car platform sill and the hoistway edge of the landing sill must be limited to what maximum value?

  1. 1.25 inches Correct answer.
  2. 1.5 inches
  3. 3 inches
  4. 1 inch

Explanation

The ordinary maximum horizontal sill-to-sill clearance for a passenger elevator is 1.25 inches (32 mm). This limits the gap passengers cross when entering or leaving the car. A 1-inch gap can comply, but it is not the maximum permitted value.

Question 29Codes and Standards (ASME A17.1/A17.1s, A17.2, A17.3, A17.4, A17.5, A17.6, A18.1)

Under ASME A17.1/CSA B44, the maximum rise for a single escalator run between landings is limited to what value?

  1. 100 feet Correct answer.
  2. 75 feet
  3. 150 feet
  4. 50 feet

Explanation

A17.1 limits a single escalator rise to 100 feet unless additional requirements are met. Beyond that rise, special design considerations and additional safety measures are needed.

Question 31Codes and Standards (ASME A17.1/A17.1s, A17.2, A17.3, A17.4, A17.5, A17.6, A18.1)

Under ASME A17.1/CSA B44, what is the minimum required height for the hoistway door locking device engagement between the latch and the keeper?

  1. 3/4 inch
  2. 3/8 inch Correct answer.
  3. 1/2 inch
  4. 1/4 inch

Explanation

The code requires that the locking device engagement be at least 3/8 inch to ensure the lock holds the door positively closed. This minimum engagement reduces the risk of the lock slipping open under load or vibration.

Question 32Codes and Standards (ASME A17.1/A17.1s, A17.2, A17.3, A17.4, A17.5, A17.6, A18.1)

Under ASME A17.1/CSA B44, what is the maximum allowable speed for a freight elevator with a rated load of 5,000 pounds?

  1. 500 fpm
  2. 300 fpm Correct answer.
  3. 400 fpm

Explanation

A17.1 limits freight elevator speed to 300 fpm for this class of equipment unless additional requirements are met. Speed limits are tied to the elevator classification and the safety equipment provided.

Question 33Codes and Standards (ASME A17.1/A17.1s, A17.2, A17.3, A17.4, A17.5, A17.6, A18.1)

Under ASME A17.1/CSA B44, machine room ventilation must maintain the ambient temperature within what range for proper equipment operation?

  1. 70°F to 120°F
  2. 50°F to 100°F Correct answer.
  3. 60°F to 110°F
  4. 40°F to 90°F

Explanation

A17.1 requires machine space temperature to be maintained between 50°F and 100°F unless the equipment is rated for other conditions. Extreme temperatures can cause controller faults and hydraulic oil viscosity problems.

Question 34Codes and Standards (ASME A17.1/A17.1s, A17.2, A17.3, A17.4, A17.5, A17.6, A18.1)

An inspector is reviewing a new traction elevator installation with a rated speed of 350 fpm. Under ASME A17.1/CSA B44, which buffer type is permitted for the counterweight?

  1. Spring buffers or oil buffers Correct answer.
  2. Oil buffers only
  3. Solid rubber buffers only
  4. No buffers are required

Explanation

For counterweights on elevators at this speed, A17.1 permits spring buffers or oil buffers depending on the rated speed and stroke required. The code permits energy-dissipating buffers meeting the specified deceleration limits.

Question 41Codes and Standards (ASME A17.1/A17.1s, A17.2, A17.3, A17.4, A17.5, A17.6, A18.1)

Under ASME A17.1/CSA B44, what is the maximum permitted vertical distance between the car sill and the landing sill when the car is at rest at a landing?

  1. 3/4 inch
  2. 1/2 inch Correct answer.
  3. 1/4 inch
  4. 1 inch

Explanation

A17.1 requires the car sill to be level with the landing sill within 1/2 inch when the car is at rest. This tolerance prevents tripping hazards and allows safe passage for passengers and equipment.

Question 42Codes and Standards (ASME A17.1/A17.1s, A17.2, A17.3, A17.4, A17.5, A17.6, A18.1)

Under ASME A17.1/CSA B44, a machine-room-less elevator with the controller mounted in the hoistway must provide which of the following?

  1. A lockable control panel with a means to prevent unauthorized access Correct answer.
  2. A dedicated machine room accessible only to maintenance personnel
  3. A remote monitoring station in the lobby
  4. An open controller cabinet for ventilation

Explanation

A17.1 requires that controllers located in the hoistway be enclosed in a lockable cabinet to prevent unauthorized access. Only qualified personnel should be able to open the control panel.

Question 43Codes and Standards (ASME A17.1/A17.1s, A17.2, A17.3, A17.4, A17.5, A17.6, A18.1)

Under ASME A17.1/CSA B44, the top-of-car operating device must be capable of stopping the car within what distance when released?

  1. 48 inches
  2. 12 inches
  3. 24 inches Correct answer.
  4. 36 inches

Explanation

A17.1 requires the top-of-car operating device to stop the car within 24 inches when the switch is released. This limits travel while a mechanic is on the car top.

Question 44Codes and Standards (ASME A17.1/A17.1s, A17.2, A17.3, A17.4, A17.5, A17.6, A18.1)

Under ASME A17.1/CSA B44, what is the required minimum depth of the pit for an elevator with a rated speed of 200 fpm?

  1. 6 feet
  2. 3 feet
  3. 5 feet Correct answer.
  4. 4 feet

Explanation

A17.1 sets minimum pit depth based on rated speed and the required buffer stroke and refuge space. For this speed, the minimum pit depth is 5 feet to provide adequate clearance below the car.

Question 45Codes and Standards (ASME A17.1/A17.1s, A17.2, A17.3, A17.4, A17.5, A17.6, A18.1)

An inspector finds an escalator with a missing comb plate tooth. Under ASME A17.2, what action is required?

  1. The escalator may operate with reduced speed
  2. The escalator may remain in service if the missing tooth is at the edge
  3. The escalator may operate if a warning sign is posted
  4. The escalator must be removed from service until the comb plate is repaired Correct answer.

Explanation

A17.2 requires that escalators with damaged or missing comb plate teeth be removed from service because the comb plate prevents objects and feet from being drawn into the step/skirt gap. Continued operation creates a serious entrapment hazard.

Question 46Codes and Standards (ASME A17.1/A17.1s, A17.2, A17.3, A17.4, A17.5, A17.6, A18.1)

Under ASME A17.4, which procedure applies when a passenger is trapped in an elevator car?

  1. The elevator should be restarted remotely without notifying the passenger
  2. The passenger should attempt to open the car door manually
  3. Trained personnel should communicate with the passenger and follow the established emergency evacuation procedure Correct answer.
  4. The fire department should always be called before any communication

Explanation

A17.4 provides guidance for emergency evacuation of passengers from stalled elevators, emphasizing communication and the use of trained personnel following established procedures. Untrained passengers should never attempt to exit the car on their own.

Question 47Codes and Standards (ASME A17.1/A17.1s, A17.2, A17.3, A17.4, A17.5, A17.6, A18.1)

Under ASME A17.1/CSA B44, the governor rope must be tensioned by a device that ensures the rope does not slacken. What is this device called?

  1. A rope equalizer
  2. A shackle assembly
  3. A rope guide shoe
  4. A governor rope tension device Correct answer.

Explanation

A17.1 requires a governor rope tension device to maintain tension on the governor rope so the governor can operate the safety in an overspeed condition. Without proper tension, the governor may fail to trip.

Question 48Codes and Standards (ASME A17.1/A17.1s, A17.2, A17.3, A17.4, A17.5, A17.6, A18.1)

An inspector is analyzing a traction elevator where the car safety device is applied by a governor. Under ASME A17.1/CSA B44, which condition must be verified regarding the governor tripping speed relative to the rated speed?

  1. The tripping speed must exceed 150 percent of rated speed
  2. The tripping speed must equal exactly 100 percent of rated speed
  3. The tripping speed must be less than the rated speed
  4. The tripping speed must be within the range specified for the safety device and not less than 115 percent of rated speed Correct answer.

Explanation

A17.1 requires the governor to trip at a speed within the range specified for the safety device, and the tripping speed must be at least 115 percent of rated speed for car safeties. This ensures the safety applies only during a genuine overspeed condition.

Question 49Codes and Standards (ASME A17.1/A17.1s, A17.2, A17.3, A17.4, A17.5, A17.6, A18.1)

Under ASME A17.1/CSA B44, when a hydraulic elevator's pressure relief valve is set, the setting must not exceed what percentage of the full-load pressure?

  1. 175 percent
  2. 125 percent
  3. 200 percent
  4. 150 percent Correct answer.

Explanation

A17.1 limits the pressure relief valve setting to 150 percent of full-load pressure to protect the hydraulic system from overpressure. Higher settings risk bursting the cylinder or piping.

Question 50Codes and Standards (ASME A17.1/A17.1s, A17.2, A17.3, A17.4, A17.5, A17.6, A18.1)

Under ASME A17.1/CSA B44, which requirement applies to the clearance between the car and the hoistway when the car is at the top landing with the counterweight at the bottom?

  1. The clearance must be limited to prevent a person from entering the space Correct answer.
  2. The clearance must permit a person to enter the hoistway
  3. The clearance must be at least 36 inches
  4. The clearance must be at least 24 inches

Explanation

A17.1 requires that the clearance above the car at the top landing be limited so a person cannot enter the space between the car top and the overhead machinery. This prevents access to hazardous areas.
