Product Details
Overview
Overhead crane reducer, or gearbox, is a mechanical component that transmits power from the motor to the crane's wheels, reducing the motor's high-speed output to a lower-speed, high-torque rotation that enables overhead crane to move smoothly and carry heavy loads.
CTECH Machinery Sdn Bhd specially produces planetary gearbox of high load distribution and efficiency; helical gearbox of hardened steel or cast iron and its systems for lubrication, cooling and anti-reverse safety.
Main components
Low voltage switchgear
Control, measurement, signal, protection, regulation and other equipment:
● Control components
● Measuring instruments
● Signal device
● Protective device
● Adjust equipment
● Gear box body and door
● Connecting cable

Basic types
1) Long travel and cross travel mechanism: helical gearbox
2) Heavy-duty construction hoist crane: planetary gearbox
3) Hoisting movements: bevel-helical gearbox

Functional features
