This part of GB 10827 gives safety requirements and the means for their verification for the following types of pedestrian-propelled trucks (hereafter referred to as trucks), equipped with load-handling devices for normal industrial duties, e.g. fork arms and platforms, or integrated attachments for special applications:
- pedestrian-propelled straddle stackers,
- pallet stackers,
- industrial trucks with capacities not exceeding 1 000 kg with manual or electrical battery-powered lifting,
- low-lift pallet trucks with lift height up to 300 mm and rated capacity up to 2 300 kg,
- scissor-lift pallet trucks with lift heights up to 1 000 mm or rated capacity up to 1 000 kg with manual or electrical battery-powered lifting.
It is applicable to trucks provided with either manual or electrical battery-powered lifting, operating on smooth, level, hard surfaces.
Note: On-board battery chargers are considered to be part of the truck. Attachments mounted on the load-carrier or on the fork arms which are removable by the user are not considered to be part of the truck.
This part deals with significant hazards, hazardous situations and events relevant to the applicable machines when used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4).
It does not establish the additional requirements for
a) climatic conditions,
b) operation in severe conditions (e.g. extreme environmental conditions such as freezer applications, high temperatures, corrosive environments, strong magnetic fields),
c) electromagnetic compatibility (emission/immunity),
d) handling of loads the nature of which could lead to dangerous situations (e.g. molten metal, acids/alkalis, radiating materials, especially brittle loads),
e) handling suspended loads which may swing freely handling,
f) use on public roads,
g) direct contact with foodstuffs,
h) operation on gradients or on surfaces other than smooth, level, hard surfaces,
i) lifting systems using belts,
j) lifting of persons,
k) trucks with overturning moment greater than 40 000 N·m,
l) scissor-lift trucks whose lifting is powered by external means (electric, pneumatic),
m) roll containers, (returnable container);
n) trucks that are intended to be towed by powered vehicles,
o) trucks designed for special applications (e.g. hospitals, restaurant trolleys),
p) winch-operated trucks,
q) mobile lifting tables.
Hazards relevant to noise, vibration and visibility are not significant and are not dealt with in this part.

3 Terms and Definitions
For the purposes of this document, the terms and definitions given in ISO 5053 and ISO 12100-1, and the following apply.
3.1
stacker truck
masted truck without tilt, with load-bearing outriggers, equipped with fork arms, a platform or other load-handling device, designed to be manually pushed, pulled and steered by one pedestrian operator
Note: The load can be raised by either manual means or battery power.
3.1.1
straddle stacker
stacking truck with outriggers, equipped with fork arms that are located between the outriggers
3.1.2
pallet stacker
stacking truck where the fork arms extend over the outriggers
3.2
pallet truck
truck with wheels supporting lifting fork arms for handling pallets, designed to be manually pushed, pulled and steered, on a smooth, level, hard surface by a pedestrian operator using an articulated tiller and designed to raise a load by pumping the tiller to a height
truck without a mast, with three or more wheels and with two fork arms or a platform, with a scissor lifting mechanism, a wheel base that varies with the lift height and lateral stabilizers, designed to be manually pushed, pulled and steered by one pedestrian operator using an articulated tiller
3.4
actual capacity
maximum load in kilograms, established by the manufacturer based on component strength and truck stability, which the truck can carry, lift and stack to a specified height, at a specified load centre distance and reach, if applicable, in normal operation
Note: The actual capacity depends on the configuration of the truck in terms of such variables as the type and lift height of the mast fitted, the actual load centre and any attachments that may be fitted. Additional capacity ratings with removable attachments can also be established where permitted by the appropriate stability tests or by calculation using empirical data (formulae).
3.5
rated capacity of removable attachments
maximum load in kilograms, which the attachment is capable of handling in normal operating conditions at the load centre distance as specified by the manufacturer of the attachment
Note: For determination, see Annex B.
3.6
rated capacity
(of a stacker truck) maximum load in kilograms given by the manufacturer, based on component strength and truck stability, that the truck can carry, lift and stack to a standard lift height, at a standard load centre in normal position
Note 1: Where a truck does not lift to the standard lift height, H, it is given a rated capacity at its maximum lift height. For determination, see Annex B.
Note 2: 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. It gives the load that the truck type is capable of transporting or lifting under the above conditions. The safe operating limits for the truck are defined by its actual capacity (see ISO 3691-1).
3.7
normal operating position
position in which the operator shall be able to control all functions for load handling as defined by the manufacturer
3.8
normal operation
intended use for which the truck is designed, according to the manufacturer's specification and defined in the instruction handbook
