The crane gear reducer is the core transmission component in the lifting equipment. Its performance characteristics directly affect the operating efficiency, stability and safety of the crane. The following are its main performance characteristics:
Hard tooth surface technology
The gear is made of 20CrMnTi alloy steel carburized and quenched (hardness 58-62 HRC) + precision grinding (ISO level 6 accuracy), and the fatigue resistance is increased by 40%.
Modular design
Supports parallel axis and planetary stage combinations, adaptable to various lifting/running/rotating mechanisms.
Long maintenance-free period
Standard labyrinth seal + double lip oil seal, IP55 protection, maintenance interval ≥8,000 hours.
Good speed regulation performance
Multi-stage reduction ratio: Through multi-stage gear combination (such as three-stage reduction), a wide range of speed ratios (common 5~200) can be achieved to meet the needs of different working conditions such as crane lifting and walking.
Matching with motor: It can be matched with variable frequency motor or hydraulic motor to achieve stepless speed regulation and adapt to precise lifting.
