Abstract / scope
ISO 22915-21:2009 specifies the tests for verifying the stability of order‑picking trucks with an elevating operator position, as defined in ISO 5053, where the operator's position can be raised to an elevation above 1 200 mm. It is applicable to industrial trucks fitted with fork arms, platforms and/or integrated attachments under normal operating conditions. It is not applicable to trucks fitted with a load carrier that can be shifted laterally or pivoted out of the truck's longitudinal centre plane.
