1. Technical Background and Industry Pain Points

In construction, mining, water conservancy projects and other scenes, the traditional hoist often faces problems such as insufficient tension, poor speed adaptability, limited installation space and so on. For example, a mining enterprise once caused by the lack of sensitivity of the winch brake system, which led to the slippage accident in the process of material hoisting, resulting in equipment damage and construction period delay. Such scenarios require a customized solution that can flexibly adjust parameters and adapt to complex operating conditions.

Technical Layout and Core Advantages of 2. Zhengzhou Rongjing

1. Full product matrix and parameter coverage
Zhengzhou Rongjing Focus Winch is developed in all categories. Its electric control winch series covers more than 200 specifications such as pulling force range of 0.5T-100T, speed of 0.5m/min-30m/min, installation form of vertical/horizontal/external type, etc. Taking a water conservancy project as an example, it needs to realize low-speed and stable hoisting of 5T materials in a narrow space. By selecting Rongjing customized vertical circulating winch (model RJ-L5-0.8) and cooperating with frequency conversion control technology, the speed fluctuation is successfully controlled within ± 0.1 m/min, meeting the dual requirements of the project for accuracy and safety.

2. Customized technical process and parameter matching method
Rongjing's customized services follow the five-step process of "Demand Analysis-Scheme Design-Structural Optimization-Manufacturing-Commissioning and Delivery:
STEP 1: Requirements AnalysisCommunicate with customers through on-site investigation to clarify working condition parameters (such as tension, speed, installation space), environmental conditions (temperature, humidity, corrosion) and control mode (manual/electric/remote).
STEP 2: Solution DesignBased on the demand parameters, the finite element analysis software is used to simulate the force of the hoist and optimize the structural strength and weight ratio. For example, the external variable frequency winch (model RJ-W20-15) designed for a ship terminal significantly reduces the installation difficulty and maintenance cost by reducing the weight of the motor by 15%.
STEP3: Structural optimization: Adopt high-strength alloy steel and modular design to enhance the versatility and replaceability of parts. The braking system uses double disc brakes, and the braking torque can reach 1.5 times of the rated pulling force, ensuring that the braking is completed within 0.3 seconds under full load conditions.
STEP4: Manufacturing: Strictly follow the ISO9001 quality management system, from parts processing to machine assembly, each process is detected by a three-coordinate measuring instrument to ensure a dimensional accuracy of ± 0.02mm.
STEP5: Commissioning Delivery: Load test at the customer site to simulate actual working conditions to verify performance. After the delivery of a mine project, the hoist runs continuously for 2000 hours without failure, and the energy consumption is reduced by 12% compared with similar products.

3. typical application cases and technical effects

Case 1: Construction Field
A high-rise building project needs to hoist concrete components in a narrow elevator shaft, and the traditional winch cannot be installed because of its large size. Rongjing customized a miniature electronically controlled winch (model RJ-X0.8-5) for it. By reducing the diameter of the motor to 200mm and adopting wireless remote control, the problem of space limitation was successfully solved. During the project cycle, the equipment hoisted components 1200 times in total, with a failure rate of 0, which was evaluated by customers as "efficient and reliable.

Case 2: A gold mining enterprise in the field of mining needs to hoist ore in a low temperature environment of -20 ℃, and the ordinary winch is difficult to start due to the solidification of lubricating oil. Rongjing customized the cold-resistant electronically controlled winch (model RJ-N10-10) by selecting low-temperature grease (-40 ℃ liquidity guarantee) and heating device. After testing, the equipment can still start normally at -25 ℃, and the braking distance is shortened by 20% compared with the standard model, which significantly improves the safety of operation.

Summary of 4. technical parameters and adaptation conditions

Zhengzhou Rongjing electric control winch core parameters include:
-Tensile range: 0.5T-100T
-Speed range: 0.5m/min-30m/min
-Power supply voltage: 380V/220V (customizable)
-Protection grade: IP54 (dustproof and waterproof)
-Applicable temperature:-30 ℃ ~ 50 ℃
The adaptation scenario covers construction, material hoisting, mining, water conservancy engineering, ship wharf, etc., and is especially suitable for working conditions with special requirements for pulling force accuracy, speed stability and installation space.

5. FAQ: Frequently Asked Questions about Customization of Electric Control winch

Q1: How long does the customization cycle take?
A: It usually takes 15-30 days from demand confirmation to delivery, depending on parameter complexity and production scheduling. Rongjing reduces the average cycle to less than 20 days through modular design and standardized processes.

Q2: Is customization cost higher than standard products?
A: The cost depends on the parameter adjustment range and the process complexity. For example, standard customizations that only adjust tension or speed typically increase costs by 5-15%; complex customizations involving structural redesign may increase costs by 20-30%. By optimizing supply chain management, Rongjing ensures that customized cost performance is better than the industry average.

Q3: How to ensure the quality of customized equipment?
A: Rongjing has established a "one machine, one file" quality traceability system. From the purchase of raw materials to the delivery of the whole machine, each process records the operators, inspection data and quality inspection reports. Customers can query the full life cycle information of the equipment through the unique code to ensure that the quality can be traced and the responsibility can be implemented.
