An aluminum alloy lever hoist mainly consists of the following parts:
Shell and Main Structure: Made of high-strength aluminum alloy (such as 7075, 6061, etc., aerospace-grade aluminum), cast or forged, lightweight and with good corrosion resistance.
Transmission Mechanism: Includes gears (or ratchet), drive shaft, clutch, etc., responsible for converting manual lever force into lifting force.
Lifting Chain: Usually equipped with an alloy steel lifting chain; some models also have chains that have undergone anti-corrosion treatment such as galvanizing.
Handle: Ergonomically designed handle, providing a labor-saving operation.
Braking Safety System: Built-in mechanical friction brake or pawl brake ensures the load can be safely locked in any position.
Hooks: Upper and lower hooks are usually made of alloy steel with safety latches, complying with safety regulations.
