3.1

self-propelled industrial variable-reach truck

seated-rider-operated, counterbalanced lift truck with one or more articulated arms [telescopic, non-slewing (3.13)] used for stacking loads and for operation on smooth, level, prepared and consolidated surfaces

3.2

actual capacity at maximum lift height with forks

maximum load, Q₂, in kg, specified by the manufacturer that the truck is capable of lifting to its maximum height in normal operating conditions

Note 1 to entry: This is equal to the maximum load, with centre of gravity, G (see Figure A.1), carried on the fork arms at the standard load centre distance, D, as specified in Annex A, and with the boom (3.7) adjusted to its maximum height.

3.3

actual capacity at container position with spreader

maximum load, Q, in kg, with row, d, and height, h, specified by the manufacturer that the truck is capable of lifting to its maximum height in normal operating conditions

3.4

axle locking

mechanism designed to stop oscillation of the rear axle so as to improve truck stability

3.5

stabilizer

extendable or pivoting mechanical supports used to improve stability of a stationary truck

3.6

lateral levelling

act of changing the angular relationship between the boom (3.7) pivot and the ground in order to adjust the boom pivot to horizontal when the truck is standing on a side slope

Note 1 to entry: Used to ensure that the boom operates in a vertical plane.

3.7

boom

pivoting support member providing radial and telescoping (if equipped) movement of the load-engaging means

3.8

spreader

device fitted to the boom (3.7) , designed to connect the lifting points of freight containers, swap bodies and semi-trailers

Note 1 to entry: This can include powered devices used to connect the lifting points of the load and an articulated mechanism to facilitate engagement.

3.9

overhead guard

device fitted to the truck for the purpose of protecting the operator against falling objects

3.10

load backrest

portion of the fork carriage serving to restrain the load when the load is tilted rearward or upward

3.11

normal operating position

position in which the operator is able to control all functions for driving and load handling as specified by the manufacturer

Note 1 to entry: Additional positions may be specified by the manufacturer if it is not possible to control all the functions of the truck from a single position. A rotating seat or stand-up end-control truck with more than one operating direction is considered as being or having a single operating position.

3.12

fork carrier

device fitted at the end of the boom (3.7) to connect and lock interchangeable attachments without the use of a tool

3.13

non-slewing

having a slewing movement not greater than 5° on either side of the longitudinal axis of the truck

Note 1 to entry: See Figure 1.

Figure 1 — Slewing movement ≤ 5° (non-slewing)

3.14

rated capacity with fork arms

load, Q₁, in kg, permitted by the manufacturer, that the truck type is capable of transporting and lifting in normal operating conditions with the boom (3.7) fully retracted

Note 1 to entry: For centre of gravity, G.

Note 2 to entry: The rated capacity is used to compare the capacity of different manufacturers’ trucks and to provide the break points used in technical standards and statistics. The operating limits for the truck are defined by the actual capacity (3.2, 3.3) .

3.15

rated capacity with spreader

load, Q₁, in kg, permitted by the manufacturer, that the truck type is capable of transporting and lifting in normal operating conditions with the spreader (3.8) in the position of the first container row at measurement d₁ and lift height 6,5 m

Note 1 to entry: For the second container, see Figure A.2.
