NCCCO Telehandler flashcards

32 cards. Read the term and the definition here. The deck at the top of this page is optional.

Walk-around inspection

A full visual and functional check of all four sides, top, and underside of the telehandler performed before each shift or whenever a new operator takes over the machine.

ROPS and FOPS

Roll-over and falling-object protective structures. Cracks, bends, or unauthorized welds remove the machine from service because field repair voids the certification.

Operator presence switch

A seat or seat-bar sensor that prevents the machine from starting or traveling unless the operator is seated with the seat belt latched.

Load chart placement

The capacity chart must be legible and mounted in the cab, and it must match the installed attachment and tire type on that specific machine.

Tire rejection criteria

Remove a pneumatic tire from service when cord is exposed, a sidewall bulge or cut is present, or tread depth falls below about 1/4 inch (6 mm).

Hydraulic level check

Check the hydraulic reservoir sight glass with the boom fully retracted and lowered so the reading reflects the true system level rather than oil trapped in the cylinders.

Out-of-service tag

A tag placed on a defective telehandler that keeps it idle until a qualified person completes and documents the repair and returns it to service.

Parking brake test

Before travel, confirm the parking brake holds the machine on a slope and the service brake stops it from low speed in both directions.

Ground bearing pressure

The load per unit area the soil must support under tires or outriggers. Compare it with verified allowable soil capacity, not with the machine's total weight.

Buried utility hazard

Unmarked trenches, tanks, and utility lines can collapse under a wheel or outrigger. Confirm locations before setup and use mats or plates only where the manufacturer permits.

Overhead line approach

Treat every power line as energized and keep the boom, load, and rigging outside the utility- or site-specified minimum approach distance at all times.

Side slope restriction

Lifting or leveling on a side slope is prohibited beyond the manufacturer's rating; the load chart assumes a level machine, and tilt reduces stability.

Excavation setback

Keep the telehandler back from an excavation edge by at least the depth of the cut or the engineered distance, whichever is greater, to prevent edge collapse.

Wind limit

Stop lifting when wind exceeds the manufacturer's limit or when the load's sail area makes it uncontrollable. Tag lines control rotation, not swing.

Site access survey

Confirm gate widths, road and floor load limits, overhead obstructions, pedestrian routes, blind corners, and spotter positions before moving the machine onto the site.

Soft ground effect

Mud, ice, loose gravel, and uncompacted fill reduce stability and can change effective capacity. Steel mats spread load only when the manufacturer permits them.

Blind lift planning

When the load or landing zone is out of view, position a designated signal person who keeps continuous contact with the operator and can stop the lift.

Load weight verification

Use shipping papers, a scale ticket, or a calculated weight with a documented margin. Appearance-based estimates are not acceptable for capacity checks.

Load chart reading order

Select the correct attachment column, enter with boom angle or radius, then read capacity at the actual boom extension and height. All conditions must be met at once.

Radius definition

The horizontal distance from the machine's center of rotation, or the manufacturer's stated point, to the center of gravity of the load.

Rigging weight deduction

Subtract the weight of slings, shackles, spreader beams, and the quick-attach device from chart capacity wherever the chart does not already include them.

Sling angle capacity

Sling capacity decreases as the angle from horizontal decreases. Use the actual angle, not the vertical rating, and never side-load the hook.

Hook latch check

Confirm the hook latch closes and the load sits in the bowl of the hook, with the load's center of gravity below the lift point to prevent tipping.

Signal person designation

One person is designated to direct the lift by hand signals or radio. Any worker on site may give a stop signal at any time.

Lift plan contents

Load weight, attachment, boom length, radius, height, capacity versus demand, ground conditions, travel path, and the emergency lowering procedure.

Tag line use

A line used to control load rotation, held from outside the load's fall zone. Never wrap it around a hand or use it to arrest a swinging load.

Frame leveling

The function that levels the chassis before raising the boom. The load chart assumes a level machine, and frame tilt reduces capacity.

Boom sequencing

Extend before lowering the angle to reach far out, and retract before raising the angle when bringing a load in, keeping the load inside the chart.

Travel position

Boom retracted and low, just above ground clearance, with the load kept uphill on grades and the machine in the manufacturer's stated travel configuration.

Capacity at height

Chart capacity can decrease as the boom is raised even at constant radius, so recheck the chart at the actual lift height, not only at ground level.

Smooth control input

Operate the frame-level and boom functions one at a time and without abrupt stops; combined functions with wind can cause oscillation the chart does not cover.

Emergency lowering procedure

The manual method, valve, or pump used to lower the boom if hydraulics fail. Locate and understand it before the lift begins.
