Which part of a forklift is primarily responsible for lifting and lowering loads?

The mast is the part of a forklift that is primarily responsible for lifting and lowering loads. It consists of vertical uprights and supports that enable the forks to move up and down. The design of the mast allows for stable lifting at various heights, providing the necessary strength and stability to handle substantial loads. It incorporates hydraulic cylinders that facilitate this lifting motion, making it an essential component for the operation of the forklift.

The base supports the entire forklift but does not actively lift loads; rather, it provides stability during operation. The forks are the components that directly engage with the loads but rely on the mast for vertical movement. The wheels are for mobility and do not play a role in the lifting mechanism. Together, these components work in unison, but the mast is specifically designed for the critical function of lifting and lowering.
