Rated Capacity

The maximum load a telescopic handler is designed to lift and place safely under stated conditions, as declared by the manufacturer for a specific combination of boom length, boom angle and attachment.

Related: Capacity Chart, Derated Capacity, Load Moment
Capacity Chart

A load plate or graph fixed in the cab that shows the maximum permitted load at each combination of boom extension and boom angle, often with different zones for different attachments.

Related: Rated Capacity, Derated Capacity, Load Moment
Derated Capacity

A reduced safe working load applied to a lift when conditions such as soft ground, high winds, uneven terrain or non-standard attachments make the published chart figures unsafe to use as they stand.

Related: Rated Capacity, Capacity Chart
Load Moment

The turning effect created by a load multiplied by its horizontal distance from the machine's tipping point; it explains why the same weight becomes dangerous as the boom is extended or lowered.

Related: Load Centre, Rated Capacity
Load Centre

The horizontal distance from the vertical face of the forks or attachment to the centre of gravity of the load, which must not exceed the value used to produce the capacity chart.

Related: Load Moment, Rated Capacity
Longitudinal Stability

The machine's resistance to tipping forwards or backwards about its front or rear axle, governed mainly by load weight, boom position and chassis counterweight.

Related: Lateral Stability, Load Moment
Lateral Stability

The machine's resistance to overturning sideways, which is reduced by travelling with the boom raised, by turning on slopes and by carrying an off-centre load.

Related: Longitudinal Stability, Travel Position
Travel Position

The prescribed boom and attachment configuration for moving the machine, typically boom retracted and lowered close to the ground with the load or forks tilted back.

Related: Lateral Stability, Boom Angle
Boom Angle

The angle of the telescopic boom measured from horizontal, read from the cab indicator and used together with boom extension to determine the permitted load from the capacity chart.

Related: Boom Extension, Capacity Chart
Boom Extension

The amount the telescopic sections are extended, shown by a length or section indicator in the cab; greater extension reduces the load the machine can safely handle.

Related: Boom Angle, Rated Capacity
Load Moment Indicator

An electronic system that senses boom angle, boom length and pressure to warn the operator, and often cut out dangerous movements, when the machine approaches its stability limit.

Related: Rated Capacity, Load Moment
Safe Working Load

The maximum mass that may be lifted by a sling, shackle or other lifting accessory in a given configuration, normally the marked working load limit reduced as necessary for the slinging method used.

Related: Working Load Limit, Sling Angle Factor
Working Load Limit

The maximum load a lifting accessory is marked and certified by its manufacturer to support in a specified configuration and use, forming the basis for selecting slings and hardware.

Related: Safe Working Load, SWL Tag
Sling Angle Factor

A multiplier applied to a load when slings are used at an angle, because the tension in each leg increases as the angle from horizontal decreases, raising the load on each sling.

Related: Safe Working Load, Two-Leg Sling
Two-Leg Sling

A lifting assembly using two legs sharing the load, where the share carried by each leg increases as the included angle between the legs opens out, reducing the safe capacity.

Related: Sling Angle Factor, Working Load Limit
SWL Tag

A durable label or metal tag attached to a sling or accessory showing its working load limit, identification and date of test or inspection, used to confirm it is fit for the lift.

Related: Working Load Limit, Lifting Accessory Inspection
Lifting Accessory Inspection

The formal pre-use and periodic examination of slings, shackles, hooks and beams to identify damage, wear, distortion or missing markings before they are used in a lift.

Related: SWL Tag, Pre-Use Check
Centre of Gravity

The point through which the whole weight of an object acts; if it lies outside the machine's stability base or off the fork centre, the load becomes unstable or reduces capacity.

Related: Load Centre, Longitudinal Stability
Stability Base

The area enclosed by the machine's ground contact points, such as the wheel footprint, within which the combined centre of gravity must remain for the machine to stay upright.

Related: Centre of Gravity, Longitudinal Stability
Pre-Use Check

The documented daily inspection carried out by the operator before work starts, covering fluid levels, tyres, brakes, steering, boom, hydraulics, alarms and safety devices.

Related: Defect Reporting, Lifting Accessory Inspection
Defect Reporting

The formal process of recording and reporting any fault or damage found on the machine or equipment so that it is assessed, repaired and signed off before further use.

Related: Pre-Use Check, Thorough Examination
Thorough Examination

A detailed periodic inspection of lifting equipment by a competent person, required by law at defined intervals, which results in a report and may impose conditions on continued use.

Related: Defect Reporting, Lifting Accessory Inspection
RIDDOR

UK regulations requiring employers to report specified workplace incidents to the enforcing authority, including certain injuries, dangerous occurrences and over-seven-day absences from work.

Related: Near Miss, Accident Reporting
Accident Reporting

The internal procedure for recording injuries, damage and dangerous events in the site accident book and escalating them as required by law and by the site management plan.

Related: RIDDOR, Near Miss
Near Miss

An unplanned event that did not cause injury or damage but had the potential to do so, which should be reported so that the underlying cause can be corrected.

Related: Accident Reporting, RIDDOR
Method Statement

A written document describing how a specific task will be carried out safely, including the sequence of work, control measures, plant used and the people responsible.

Related: Risk Assessment, Permit to Work
Risk Assessment

A structured process of identifying hazards, judging who might be harmed and how, and deciding on control measures that reduce risk to an acceptable level.

Related: Method Statement, Hierarchy of Control
Hierarchy of Control

The order in which risk controls are chosen, starting with eliminating the hazard and moving through substitution, engineering controls and safe systems of work to personal protective equipment last.

Related: Risk Assessment, Personal Protective Equipment
Permit to Work
