As the key model in the winch family, the vertical circulating winch plays an important role in the fields of construction and material hoisting with its compact structure and flexible adaptability.Zhengzhou Rongjing Machinery Equipment Co., Ltd. has been deeply engaged in the field of lifting equipment for many years. For the research and development and production of vertical circulating winch, it has formed a full-process technical system covering design, material selection, manufacturing and service, providing safe and reliable lifting solutions for global customers.

STEP1: full category coverage to meet diverse needs
Zhengzhou Rongjing's vertical circulating hoisting machine belongs to an important branch of the whole category hoisting machine product line, which is complementary to the electric control hoisting machine, planetary handbrake hoisting machine and other models. Its specifications and models are rich, the pulling force range is adjustable from 1 ton to 50 tons, the speed classification is accurate, it supports various installation forms such as vertical and horizontal, and can be adapted to scenes such as concrete pouring in construction, heavy cargo handling in material hoisting, and underground equipment lifting in mining. For example, in a water conservancy project, the customer selected Rongjing vertical circulating winch to complete the gate opening and closing operation, the equipment through customized tension parameters and anti-corrosion coating design, continuous operation for 3 years without failure, effectively ensuring the progress of the project.

STEP 2: Personalized Customization to Resolve Challenges in Special Operating Conditions
In view of the needs of customers such as limited space and special control methods, Zhengzhou Rongjing provides one-stop customized services from scheme design to production and manufacturing. The technical team will survey the working conditions on the spot and optimize the structural size and power configuration of the winch in combination with the installation environment, frequency of use and other factors. For example, due to the narrow deck space of a ship terminal customer, the winch needs to be installed on the side of the column. Rongjing team successfully developed a side-mounted vertical circulating winch by adjusting the position of the motor and the layout of the transmission chain, which not only met the space requirements, but also ensured the hoisting efficiency. Such cases are also reflected in the field of mining, in view of the underground high temperature and high humidity environment, customized models using reinforced sealing structure and high temperature bearing, prolong the service life of the equipment.

STEP3: Strictly Control Quality and Build a Secure Defense Line
Zhengzhou Rongjing implements strict standards in the production of vertical circulating winch from the selection of raw materials to the delivery of finished products. The main structure adopts high-strength alloy steel, and the fatigue resistance is improved by heat treatment process; the brake system uses imported friction plates to ensure braking sensitivity; the transmission parts pass high-precision processing and dynamic balance test to reduce operating vibration. Each equipment shall pass the 72-hour continuous load test to detect the operation stability, temperature rise control and other indicators, and can be delivered only after passing the test. For example, in a construction project, Rongjing vertical circulating winch has been operating continuously for 6 months with an average of 12 hours per day. During this period, only routine lubrication and maintenance are required without any failure. The customer feedback that it "starts smoothly, consumes reasonable energy and significantly reduces operating costs".

STEP 4: End-to-end service to enhance customer experience
In addition to product performance, Zhengzhou Rongjing focus on the integrity of the service chain. In the pre-sales stage, the technical team communicates with customers in depth and provides model selection suggestions and scheme matching. In the sales stage, special personnel will be assigned to follow up the production progress to ensure the delivery time. In the after-sales stage, a 24-hour response mechanism will be established to provide remote guidance and on-site maintenance support. For example, an overseas customer encountered operational problems in the installation and commissioning of equipment. Rongjing guided the adjustment of parameters through video connection and solved the problem within 2 hours, thus avoiding the delay of the project. This "customer-centric" service concept has enabled Rongjing vertical circulating winch to win long-term trust in the domestic and foreign markets, and the customer re-purchase rate continues to maintain a high level.
