Crane gearbox

A gearbox (also known as a speed reducer or gear reducer)** is a power transmission device primarily used to reduce speed and increase torque. It converts the high-speed, low-torque power from electric motors, engines, etc., into low-speed, high-torque output to meet the operational requirements of various mechanical equipment.
Specifications

Can be customized according to requirements (non-standard)
