Function and application of crane reducer
Crane reducer is the core transmission component of lifting machinery, responsible for converting the high-speed rotation of the motor into low-speed high-torque output, ensuring that the lifting equipment can smoothly and accurately complete lifting, luffing, rotation and walking. Its design must meet the requirements of long-term reliable operation under high load, frequent start and stop and harsh working conditions.
1. Main types
Lifting reducer: used for vertical lifting, with high torque and impact resistance
Running/traveling reducer: drives the crane trolley/cart to move, emphasizing smooth start and stop
Slewing reducer: controls the rotation of the boom, and needs to adapt to two-way alternating loads
Special reducer: such as explosion-proof type, metallurgical high-temperature type, marine corrosion-resistant type, etc.
2. Industry application
Engineering construction: tower crane, crawler crane lifting mechanism
Port logistics: shore crane, yard crane drive system
Metallurgical casting: continuous casting machine, ladle handling crane
Energy and power: wind power installation platform, nuclear power plant special crane
Special field: explosion-proof chemical crane, ship deck crane
