This standard specifies the basic tests for verifying the stability of walk-behind and ride-on pallet trucks and high-lift platform trucks. This standard is applicable to stacker trucks and moving trucks with a rated lifting capacity not greater than 5,000 kg, and whose mast, loading platform, and fork can be tilted or not. Also suitable for vehicles fitted with load handling attachments under the same operating conditions. This standard does not apply to vehicles with retractable devices (such as masts or forks), nor to vehicles handling suspended loads that can swing freely.
