Analysis of the core advantages of 1. planetary handbrake winch

As the star product of Zhengzhou Rongjing Machinery Equipment Co., Ltd., planetary handbrake winch occupies an important position in the field of lifting equipment with its unique planetary gear transmission structure and handbrake braking system. This model achieves high torque output through multi-stage planetary gear reduction, and with a mechanical handbrake device, it can quickly brake in the event of a power failure or emergency to ensure safe operation. Its core parameters include: rated pulling force range of 5-50 tons, braking torque of up to 2000N · m, support for 0-15 m/min stepless speed change, which can meet the precise hoisting requirements of construction, mining and other scenes.

2. Technical Parameters and Scene Adaptability

Zhengzhou Rongjing's planetary handbrake winch adopts modular design and provides a variety of specifications and models. Take the RJ-XZ-20 type as an example, its motor power is 22kW, the wire rope diameter is 22mm, and the drum rope capacity is 200m, which can be adapted to extreme environments from -20 ℃ to 50 ℃. In water conservancy projects, the model has been successfully applied to the gate opening and closing project of a hydropower station by installing anti-corrosion coating and sealing structure, and has been running continuously for 3 years without failure. In the scene of ship terminal, its low-speed and high-torque characteristics can accurately control container hoisting, shorten the braking distance to less than 0.5 meters, and significantly improve the operation efficiency.

3. customized services and industry practice cases

According to the special needs of a mining enterprise, Zhengzhou Rongjing technical team customized the planetary handbrake winch: by optimizing the heat dissipation structure of the gear box, the continuous operation temperature was reduced from 85 ℃ to 65 ℃; Add explosion-proof motor configuration to meet the safety standards of underground operation. After the transformation of the equipment in an iron ore project to achieve a daily average of 12 hours of continuous operation, the failure rate is reduced by 40%. Customer feedback shows that the operation simplicity of the model has been improved by 30%, the maintenance cycle has been extended to 6 months, and the overall cost has been reduced by 25%.

4. whole process service guarantee system

Zhengzhou Rongjing provides full-cycle service from pre-sales consultation to after-sales maintenance for planetary handbrake winches. In the pre-sales stage, the technical team recommended a combination of RJ-XZ-15 type and RJ-XZ-30 type through on-site investigation and customer working condition analysis, and successfully solved the hoisting requirements of different floors of a construction site. In the after-sales stage, a 24-hour response mechanism will be established, and a professional maintenance team and spare parts warehouse will be equipped to ensure that the equipment failure will be repaired within 48 hours. According to statistics, its service network has covered 32 provincial administrative regions across the country, and customer satisfaction has reached 98.6 percent.
