What is QJ series crane reducer?
QJ series crane reducer is a heavy-duty gear reducer specially designed for lifting equipment. It is widely used in various types of bridge cranes, gantry cranes and other heavy machinery transmission systems in transportation, metallurgy, mining, etc. Its design meets the needs of high-intensity load transmission and is famous for its high efficiency, stability and long life.
Features of QJ series crane reducer
Wide reduction ratio range, nominal speed ratio 10-200
High transmission efficiency: Optimized gear meshing design, transmission efficiency is as high as over 95%, improving equipment operating efficiency.
Smooth transmission: The gears are precisely processed, the transmission is smooth, and the noise is low. It is suitable for lifting equipment that requires high transmission stability.
High load-bearing capacity: Hard-tooth surface gears made of high-quality alloy steel materials are suitable for heavy-load conditions.
Compact structure: modular design, easy to install and maintain; small size, takes up less space, suitable for environments with limited equipment space.

How to choose a suitable QJ crane reducer?
When selecting a QJ series crane reducer, you need to consider the following key factors:
1. Load capacity
Determine the rated load capacity and peak load of the crane, and select sufficient output torque specifications based on equipment requirements.
2. Transmission ratio
Select the appropriate transmission ratio according to the required lifting speed and operating speed to ensure that the speed and safety factor match the actual needs.
3. Installation space
Choose horizontal or vertical installation according to the equipment design to ensure that the reducer is coordinated with other components of the equipment.
4. Working environment
If it is used in high or low temperature environments, it is necessary to choose a lubrication solution and sealing material that adapts to the environment. Anti-corrosion or explosion-proof designs can be selected in special environments.
QJ series reducer has become an ideal choice for heavy-duty lifting equipment due to its advantages of high load-bearing capacity, stable transmission, long life and strong adaptability.
