Defines dynamic tests for the verification of lateral stability for counterbalanced lift trucks according to EN ISO 3691-1 that have a centre control, sit down, non-elevating operator, with a rated capacity up to and including 5 000 kg when travelling on smooth level ground with the forks in travelling position.

This European Standard specifies dynamic tests for the verification of lateral stability for counterbalanced lift trucks according to EN ISO 3691-1 that have a centre control, sit down, non-elevating operator, with a rated capacity up to and including 5 000 kg when travelling on smooth level ground with the forks in travelling position. The standard is not applicable for Rough Terrain forklift trucks.

NOTE 1 Experience shows that counterbalanced lift trucks with a rated capacity over 5 000 kg are not significantly affected by lateral instability.

The requirements are specific to the various drive systems (e.g. Electric-/Internal-Combustion-Engine trucks), taking account of their varying influence on dynamic stability performance.

This European Standard does not cover the risk of a lateral tip over associated with driving backwards.

NOTE 2 Research has shown that driving backwards in typical working operations, such as unloading of a lorry, does not cause lateral instability. For this reason, only driving forward needs to be tested.

Risks due to falling off a loading dock or turning on a ramp are not covered by this European Standard.

Risks due to lifting or manoeuvring operations are covered by the respective stability tests.
