Dock Plate
A dock plate (or dock leveler) is a bridge that spans the gap between a truck trailer deck and a loading dock platform, allowing forklifts and pallet jacks to move freight smoothly between the two surfaces.
In Depth
Dock plates are essential at loading docks where the trailer height doesn't perfectly align with dock height, which varies from 44–52 inches. Proper dock plate placement ensures safe forklift entry into the trailer and prevents equipment and freight damage.
Drivers generally do not control the dock plate — dock workers manage it. However, drivers should verify the dock plate is properly positioned and rated for the forklift weight before allowing dock equipment into the trailer. Improper dock plate use can damage the trailer's floor or cause equipment tip-overs.
Portable dock plates carried by some drivers serve the same purpose and are useful for delivery locations without permanent dock equipment.
Usage Example
Example: 'The dock was 2 inches higher than my trailer floor. The receiver deployed the dock plate so their forklift could drive in without scraping.'

Pallet Jack
A pallet jack (also called a pallet truck) is a manual or powered tool used to move palletized freight on smooth surfaces. Manual pallet jacks are standard tools many drivers carry; electric powered pallet jacks are typically found in warehouse operations.
Liftgate
A liftgate is a powered platform mounted on the rear of a trailer that can be raised and lowered to transfer freight between ground level and trailer deck height. Liftgate service is required for deliveries where no loading dock is available.
Lumper
A lumper is a third-party labor worker hired to unload freight at a distribution center or warehouse. Lumper fees are typically $50–$200 and are often paid by the carrier and then billed back to the shipper or broker.
Live Load/Unload
A live load or live unload is a freight appointment where the driver must wait on-site while the freight is loaded or unloaded, as opposed to a drop and hook arrangement. Wait times of 1–4 hours are common at busy distribution centers.
Frequently Asked Questions
What is the difference between a dock plate and dock leveler?
