1 Scope

This part of GB/T 26949 specifies a three-way stacker forklift that verifies that the operator's position may or may not rise (eg ISO 5053-1)

Test method for the stability of the definition).

This section applies to vehicles with forks, shuttle forks and/or integral attachments under normal operating conditions.

This section also applies to vehicles in which the load handling device can be moved sideways or rotated and offset from the longitudinal center plane of the vehicle.
