A Docked Trailer Can Move While the Forklift Is Inside

Controls to confirm

• Immobilize the vehicle before entry: apply the vehicle and trailer parking brakes and verify the specified wheel chocks or suitable dock restraint are correctly engaged. Use required stabilizers and suitable support for an uncoupled trailer; stop if restraint or stability cannot be confirmed.
• Check the crossing before the forklift enters: inspect the trailer floor for damage, confirm the dockboard or leveller is secured and rated for the forklift plus its load, and verify adequate lighting and clearance. Keep pedestrians away and stop immediately if a gap or movement develops.
• Control departure with one agreed release process: brief the driver and loading team, use the site's positive drive-away prevention arrangement, and identify the person authorized to release the vehicle. Release only after people and equipment are clear and the dock equipment has been safely withdrawn.

Today’s action

Before the next trailer is boarded, walk through the entry-and-release checks with the driver and loading supervisor. Confirm the restraint, trailer support, floor and dock crossing are suitable; stop loading and report any missing or uncertain control.
