1 Scope

This standard specifies the stability associated with the safety of industrial vehicles as defined by ISO 5053 and verification methods. This standard is involved Industrial vehicles are self-propelled or pedestrian vehicles with wheels, except vehicles that operate on orbit. These vehicles can be operated by the operator Controlled, or unmanned, for handling, towing, jacking, lifting, stacking or stacking within shelves.

This part of GB/T 26949 specifies additional tests to verify the stability of a fully loaded vehicle with load bias in service the center of mass has a significant offset from the longitudinal center plane of the vehicle. This section applies to the following types of vehicles.

a) Counterbalanced forklift trucks as specified in ISO 22915-2;

b) Forward type (retractable masts or forks) and pin-type forklifts specified in ISO 22915-3;

c) Pallet stacker trucks as specified in ISO 22915-4;

d) Two-way and multi-way operation (retractable masts or forks) as specified in ISO 22915-7;

e) off-road telescopic handler as defined in ISO 22915-14;

f) articulated steering counterbalanced forklifts as specified in ISO 22915-15;

g) Telescopic handler of ISO 22915-11;

h) Cross-country forklift with gantry as specified in ISO 22915-13.

If the offset is greater than the following value is considered a significant offset.

--- Rated vehicle weight less than 5000kg. 100mm;

--- Rated starting weight of not less than 5000kg and not more than 10000kg of vehicles. 150mm;

--- Rated starting weight greater than 10000kg and less than.20000kg vehicles. 250mm;

--- Nominal weight of not less than.20000kg vehicles. 350mm.

5 Stability verification

The stability of the vehicle at full load and at maximum lifting height shall be determined according to the type of vehicle, in accordance with ISO 22915-2 in Test 3, Test 3 in ISO 22915-3, Test 3 and Test 4 in ISO 22915-4 (when a double-deck stacker carries two loads Only verified by Test 8 in ISO 22915-4, Test 4), or ISO 22915-72.

6 Mark

The lifting capacity and offset under special operating conditions as determined by this additional stability test shall be specified in accordance with ISO 3691-1 the operator can be seen in the normal operating position on the sign.

2) Other types of vehicles may be involved in other parts of ISO 22915, see Foreword.
