A dock leveler is a device used in warehouses and loading docks to bridge the gap between a truck and the loading platform. It helps create a smooth transition for forklifts and other equipment, making it easier to load and unload goods. By adjusting to different truck heights, dock levelers enhance safety and efficiency during the shipping process. These levelers come in various types, including hydraulic, mechanical, and pneumatic models. Each type has its own advantages, such as ease of use or lower maintenance costs. Overall, dock levelers play a crucial role in streamlining logistics and improving workplace safety.
