With unity, pioneering and innovative enterprises, and new and old friends, we will go hand in hand in economic construction, support each other, and create a brilliant tomorrow.
Overhead crane reducers are equipment used for deceleration and are widely used in docks, construction, steel mills, and other industries that require lifting heavy objects.
Overhead Crane Reducers Classification
Hard Tooth Surface Gear Overhead Crane Reducers
The overhead crane reducers are welded with steel plate, the box body is annealed and stress-relieved, and the boring and milling machining center is used for processing. The gears are made of high-quality low-carbon alloy steel, the tooth surface is carburized and quenched, and the gear grinding machine group is ground in a constant temperature workshop. The product quality is stable and the performance is reliable.
Applicable conditions
- Gear circumference speed is not greater than 20m/s
- High-speed shaft speed is not greater than 1500r/min
- The working ambient temperature is -40 degrees Celsius~+45 degrees Celsius
- Can move in both positive and negative directions

Medium Hard Tooth Surface Gear Overhead Crane Reducers
QJ series reducers are suitable for various operating mechanisms of cranes, and are also widely used in the transmission mechanisms of various machinery and equipment such as transportation, metallurgy, mining, chemical industry, light industry, etc.
Applicable conditions
- Wide range of reduction ratios, nominal speed ratio 10~200; 2. High mechanical transmission efficiency: up to 96% in the second stage and 94% in the third stage.
- Smooth operation and low noise.
- Since 42CrMo and 35CrMo are forged and tempered to make gear shafts and gears respectively, they have a long service life and high carrying capacity; they are easy to disassemble and inspect, and easy to install.
- Gear circumference speed is not greater than 16m/s.
- High-speed shaft speed is not greater than 1000r/min.
- The working ambient temperature is -40T~45TC.
- It can operate in both positive and negative directions.

Soft Tooth Surface Gear Overhead Crane Reducers
Mainly used in lifting, mining, general chemical industry, textile, light industry and other industries.
Applicable conditions
- The circular speed of the gear transmission of the reducer is not greater than 4m/s, and the speed of the high-speed shaft of the reducer is not greater than 1500 rpm. The reducer is used for forward and reverse operation.
- The working ambient temperature of the reducer is -40 degrees Celsius~+40 degrees Celsius
- This reducer has nine transmission ratios, nine configuration types and three low-speed shaft end forms.

Large Transmission Ratio Cylindrical Gear Overhead Crane Reducers
This type of large transmission ratio reducer increases the first-stage high-speed three-stage reducer than ordinary reducers, expanding the transmission ratio of the reducer.

Vertical Cylindrical Gear Overhead Crane Reducers
The reducer is a soft tooth surface reducer, and the installation method is vertical installation. It is commonly used as a reducer for trolley operation on the lifting trolley of traditional bridge gantry cranes. It is connected to the walking wheel set through couplings, drive shafts, etc.
