Core Pain Points for Dedicated Crane Reducers
1. High-Load Frequent Starts and Stops, Leading to Gear Wear and Tooth Breakage
Lifting and luffing actions involve high impact, resulting in frequent tooth surface fatigue pitting and tooth breakage, and requiring constant repairs.
2. Rapid Temperature Rise and Poor Heat Dissipation, Leading to High-Temperature Shutdowns
During continuous heavy-load operation, oil temperature soars, causing seal aging and oil leakage, forcing shutdowns for cooling.
3. Severe Oil Leakage and High Maintenance Costs
Oil seepage at oil seals and joint surfaces contaminates the site, necessitating frequent oil changes, refills, and seal replacements.
4. High Noise and Strong Vibration, Affecting Equipment Life
Insufficient gear precision and poor installation coaxiality transmit vibrations to the entire machine, accelerating structural fatigue.
5. High Starting Impact and Unstable Braking
Excessive rigidity of the reducer causes noticeable start-stop impacts, leading to load sway and creating safety hazards.
6. Large Volume and Heavy Weight, Restricting Installation
Crane spaces are compact; traditional reducers are bulky and heavy, hindering lightweight design and energy efficiency.
7. Uneven Service Life and Non-Interchangeable Parts
Many non-standard parts with poor interchangeability mean that failure of one component requires a full unit overhaul, resulting in significant downtime losses.
8. Insufficient Low-Speed, High-Torque Performance
Under heavy load and low speed, torque is insufficient, and slippage occurs, compromising the lifting capacity.
