One, deeply cultivate the crane equipment field, build a full category winch matrix

Zhengzhou Rongjing Machinery and Equipment Co., Ltd. has been focusing on the research and production of winches for over a decade, forming a technical system covering a full range of products including electric winches, planetary handbrake winches, vertical circulating winches, and external variable frequency winches. As the core product, the electric winch achieves flexible configuration with a tensile range of 5-200 tons and a speed of 0.5-20m/min through modular design, supporting horizontal/vertical installation, single/double rope winding, and various working conditions. It has been successfully applied in eight industries such as construction, mining, shipyards, and more.

Section 2: Personalized Customized Services Solve Special Working Condition Challenges

For non-standard operation scenarios, the company has established a full-process customized system covering "requirement analysis - solution design - structural optimization - production manufacturing." Taking a 200-meter deep well lifting project of a certain mining enterprise as an example, the technical team has customized the equipment by adding fall prevention devices, optimizing the braking system's heat dissipation structure, and using corrosion-resistant coatings, enabling stable operation in -20℃ low-temperature environments and high humidity conditions, extending the service life by 40% compared to standard models. Currently, the proportion of customized services has reached 35% of the company's total order volume, with a customer repurchase rate of 82%.

3. Quality control constructs a safety production defense line

From raw material selection to finished product shipment, the company implements a "three inspections and three tests" quality control standard: the parts processing stage uses a CMM three-coordinate measuring machine for 0.01mm precision detection; the assembly phase implements a torque monitoring system to ensure bolt tightening meets standards; and the whole machine testing phase verifies structural strength through destructive tests at 200% of the rated load. Customer feedback from a water conservancy project shows that Rongjing winches have operated continuously for 18 months without failure, achieving a reliability 60% higher than the industry average.

4. Full Lifecycle Service Enhancement to Increase Customer Value

The company has established a service system of "pre-sales technical consultation - in-sales solution matching - after-sales 24-hour response", equipped with a 15-person professional team providing remote diagnostics and on-site maintenance support. For overseas customers, multi-language operation manuals and video tutorial libraries have been developed, and 5 spare parts warehousing centers have been set up in Southeast Asia, the Middle East, and other regions to achieve a 48-hour spare parts delivery service. Statistics from an international port customer show that through Rongjing's preventive maintenance program, equipment downtime has been reduced by 75%, and annual maintenance costs have decreased by 32%.
