Industrial Trucks - Safety Requirements and Verification -
Part 3: Additional Requirements for Trucks with Elevating
Operator Position and Trucks Specially Designed to Travel
with Elevated Loads
1 Scope
This document specifies the safety requirements and verification methods for the following
industrial trucks with a vertical and non-tilting mast in addition to those specified in GB/T
10827.1-2014:
a) trucks with an elevating operator position and order-picking trucks as defined in GB/T
6104.1-2018; the lifting height of the elevating operator position and the load-
handling device from the ground is greater than 1,200 mm;
b) lateral-and front-stacking trucks defined in GB/T 6104.1-2018, which are designed to
operate with a load-handling device with a lifting height of greater than 1,200 mm
from the ground. When the truck is operating, the load-handling device can be lifted,
lowered or side-shifted with or without a load.
These trucks are designed to operate indoors on smooth and level pavements (for example,
concrete), and may be applied in guided, unguided or a combination of the two; this type of
trucks is not intended for towing or jacking.
This document does not apply to stacking trucks carrying two loads, with one load on the fork
and the other on the support arm. GB/T 10827.1-2014 applies to this type of trucks.
This document does not apply to trucks with the elevating operator position lifting height of not
greater than 1,200 mm, or trucks specially designed to operate with an elevated load having a
fork whose lifting height from the ground is not greater than 1,200 mm.
This document does not apply to low-level order pickers with the elevating operator’s position
not greater than 1,200 mm, which can be equipped with an additional load lifting device with a
maximum lifting height of 1,800 mm.
This document deals with all major hazards, hazardous states or hazardous events listed in
Appendix A concerning the application of the machinery for the intended use by the
manufacture and the misuse under foreseeable conditions.
This document does not include hazards that may arise when the truck is used on the highway
or operated in a potentially explosive atmosphere.

If the defined walking surface is not installed in place, then, a mechanical guard as specified in
4.4.5.1 and 4.4.5.2 shall be installed between the operator position and the load-handling device;
alternatively, the operator position shall be prevented from lifting more than 1,200 mm.
On the other end of the operator position, the intermediate rail and the toe board may be omitted,
but there shall be a top rail.
4.4.5.5 Platforms equipped with a fall protection device
For standing platforms that are not equipped with a protection system, the fall protection device

If two people are to use the same anchorage point, then, the test mass shall be 270 kg.
4.4.5.7 Prevention of being trapped
When the truck is used in very narrow aisles, if the height of the operator position is more than
3,000 mm above the ground, and the enclosure of the operator position may cause the operator
to be trapped, then, the door shall be designed to facilitate opening from the outside, or other
exits / accesses shall be provided (for example, trapdoors).

of 100 kg evenly distributed on any 0.16 m2 area.
b) If the floor is fitted with glazing, then, it shall have the same supporting strength as
the floor or be protected to the same standard as the floor. Safety glasses (such as:
tempered glass and laminated glass) shall be used. Alternatively, plastic can be used.
c) When using grated flooring, the holes or openings shall not allow the passage of
spheres with a diameter of 20 mm. Under any circumstance, the cross-section of each
opening shall not exceed 400 mm2.
4.4.5.9 Sides fitted with glazing
