What is a Mechanical Dock Leveler?
A mechanical dock leveler is a widely used loading equipment designed to bridge the height gap between a truck bed and a warehouse dock. It enables seamless connection through manual operation, allowing forklifts and pallet trucks to move in and out quickly, thus improving loading and unloading efficiency.
Unlike hydraulic or electric dock levelers, mechanical dock levelers do not require power supply. Instead, they rely on a lever and spring system to achieve lifting and positioning. With a simple structure and low maintenance cost, they are particularly suitable for cost-sensitive warehouses and logistics facilities with stable operating conditions.
Working Principle
Main Components
A mechanical dock leveler mainly consists of the following parts:
- Deck Plate: The load-bearing surface made of anti-slip checkered steel.
- Lip: The extendable part that connects to the truck bed, often with bumpers for protection.
- Balance Spring System: Provides support and lifting assistance, ensuring easy operation.
- Operating Handle: The key control part for manual lifting.
- Base Frame: Fixed on the dock foundation, bearing the entire load.
Operation Process
- The operator pulls the handle to lift the platform.
- The balance spring provides lifting assistance.
- The operator positions the platform onto the truck bed.
- Forklifts or pallet trucks can pass smoothly to load and unload goods.
- After completion, the platform returns to its original position.
