STEP 1: R&D across all product categories, catering to the needs of multiple industries.

Zhengzhou Rongjing Machinery Equipment Co., Ltd. has been deeply engaged in the field of hoisting machines for many years. With electric control hoisting machines as its core products, it has simultaneously developed a full range of models such as planetary handbrake hoisting machines, vertical circulating hoisting machines, and external variable frequency hoisting machines. Its product specifications and models are rich, the pulling force ranges from 1 ton to 200 tons, the speed can be adjusted widely, and the installation form is flexible to adapt to the needs of construction, mining, water conservancy projects, ship docks and other scenarios. For example, in mining, the explosion-proof electronically controlled winch provided by the company meets the dust-proof and explosion-proof requirements of underground operations through special structural design; in water conservancy projects, the vertical circulating winch becomes the ideal choice for gate opening and closing due to its compact structure and efficient transmission.

STEP 2: Personalized customization for precise condition matching

In addition to standardized products, the company leverages its expert technical team to offer end-to-end customized services, spanning everything from solution design to manufacturing. Taking a ship terminal customer as an example, its operating space is limited and the lifting height needs to be adjusted frequently, the company designed a compact external variable frequency winch by optimizing the size of the winch drum and motor power, which not only saves installation space, but also realizes stepless speed adjustment through variable frequency control to improve operation efficiency. In another case, according to the special pulling force requirements of a mine customer, the company adjusted the gear ratio and wire rope specifications and customized a planetary handbrake winch with a pulling force of 150 tons. After actual testing, its braking sensitivity and carrying capacity are better than industry standards.

STEP3: Quality Assurance, Safety and Efficiency

The company strictly controls the raw materials and production process, the main body of the winch is made of high-strength alloy steel, heat treatment and precision processing to ensure structural strength and wear resistance. For example, the motor of the electronically controlled winch is a well-known brand product with a protection level of IP55, which is suitable for harsh working conditions; the brake adopts a dual-circuit hydraulic system with short braking distance and high stability. In the quality inspection process, from the processing of parts to the assembly of the whole machine, each process is tested by three-coordinate measuring instruments, tensile testing machines and other equipment to ensure stable product operation and low failure rate. A construction company reported that the Rongjing winch purchased by it still maintained a zero-fault record after 12 months of continuous operation, significantly reducing maintenance costs.

STEP4: Service upgrade, full process support for customers

The company is customer demand-oriented, providing pre-sales consulting, program matching, after-sales response of the whole process of service. In the pre-sales stage, the technical team provides equipment selection suggestions according to the customer's working conditions; in the sales stage, the installation scene is simulated through 3D modeling to optimize the equipment layout; in the after-sales stage, a 24-hour response mechanism is established to quickly solve customer problems. For example, an overseas customer encountered a language barrier during equipment commissioning, and the company assisted him in completing operation training through video conferencing and multilingual manuals; another customer needed to adjust the equipment parameters due to changes in working conditions, and the company sent engineers to modify the equipment on site and resumed production in only 3 days. This "one-stop" service mode makes Rongjing machinery and equipment win long-term trust in domestic and foreign markets.
