STEP 1: Full category coverage, catering to diverse needs

Zhengzhou Rongjing Machinery and Equipment Co., Ltd. specializes in the field of lifting equipment. Its planetary handbrake winch is one of its core products, covering the full range of models including electric controlled winches, vertical reciprocating winches, and external variable frequency winches. Taking the construction of buildings as an example, in a large-scale bridge project, the customer needs to meet both high-altitude hoisting and low-speed stable operation requirements. Zhengzhou Rongjing achieves flexible matching with a traction range of 5-50 tons and a speed of 0.5-15m/min by combining the planetary handbrake winch with the vertical reciprocating model, effectively shortening the construction period by 30%. The product specifications are rich and can adapt to explosion-proof environments for mining, high humidity conditions for water conservancy projects, and salt mist corrosion scenarios at shipyards, truly realizing the "multi-functional single machine."

STEP 2: Customized Solutions, Break Special Working Condition Challenges

In addition to standardized products, Zhengzhou Rongjing offers a full-process customization service from design to manufacturing. A mining enterprise, due to the narrow tunnel space, was unable to install traditional winches. The company's technical team successfully developed a compact handbrake winch by optimizing the planetary gear box structure and reducing the brake volume, reducing the overall height by 40% and the braking distance to within 0.8 meters, meeting the continuous operation requirements underground. Customization cases show that 90% of customers have achieved seamless integration with the existing working conditions by adjusting the control method (such as remote control, PLC integration) or installation form (vertical/horizontal).

STEP 3: Strict quality control, fortify the safety line

The product is made of high-strength alloy steel materials and the gear wear resistance is enhanced through heat treatment technology. Key components like the brake have passed a fatigue test of 100,000 cycles, ensuring no failure during long-term use. In a water conservancy project, the Zhengzhou Rongjing winch operated continuously for 18 months without any brake failure or structural deformation, with customers reporting "20% better stability than similar products." Moreover, the product features low starting current and low energy consumption. For a 5-ton model, the no-load power is only 2.2kW, 15% more energy-efficient than traditional models, reducing the customer's operating costs.

STEP 4: Full-process Service, Enhance Customer Experience

Zhengzhou Rongjing has established a service system of "pre-sales consultation-solution matching-after-sales response", offering technical solutions within 72 hours and on-site fault resolution within 48 hours. A foreign client encountered language barriers during the equipment debugging phase. The company assisted the client in completing the installation through video guidance and multi-language manuals, and trained the operators to master basic maintenance skills. Currently, the products have been exported to Southeast Asia, the Middle East, and other regions, winning long-term cooperation with clients and achieving a repurchase rate of 65% through stable performance and considerate service.
