ISO 5766:1990 PDF

This International Standard specifies the basic tests for verification of the stability of pedestrian- and rider-controlled pallet stackers and high-lift platform trucks. It applies to such stackers and trucks with tiltable and non-tiltable masts, or tiltable or non-tiltable load platforms or fork arms, of rated capacity up to and including 5000 kg (10000 lb). It also applies to trucks operating under the same conditions when equipped with load-handling attachments.

This International Standard does not apply to trucks with retractable devices, such as mast or fork or when handling suspended loads which may swing freely.
