1. Technical Background: The core requirements for the customization of electronically controlled winch

As a key component of lifting equipment, the performance of electronically controlled winch directly affects the efficiency and safety of construction. In construction, mining and other scenarios, customers often face challenges such as complex working conditions, limited space, and diverse pull requirements. For example, a mine project needs to realize the vertical hoisting of 50 tons of materials in a narrow roadway, and the traditional standardized equipment is difficult to meet the requirements of space and power matching. Zhengzhou Rongjing Machinery Equipment Co., Ltd. through customized design, from the motor selection, drum structure to the control system are targeted optimization, and finally achieve the balance of equipment compact and power output.

2. Technology Analysis: Four Key Modules of Customized Design

1. Condition demand analysis module: Through site survey and data modeling, the required pulling force range (e. g. 3-200 tons), operating speed (0.5-15 m/min) and installation space limitation of the equipment are defined. For example, a water conservancy project needs to operate in a humid environment for a long time. The team selected IP65 protection grade motor and stainless steel drum to ensure the corrosion resistance of the equipment.

2. structural optimization design moduleFinite element analysis (FEA) is used to simulate the stress of the key components such as the drum and bracket, and optimize the material thickness and the layout of the reinforcing ribs. Taking the vertical circulating winch as an example, the balance between light weight and high strength is realized by reducing the weight of the drum by 15% and increasing the carrying capacity by 20%.

3. Control System Integration Module: Support frequency conversion speed regulation, PLC remote control and other function customization. A ship terminal project needs to realize the synchronous operation of multiple devices. The team has developed a centralized control system based on Modbus protocol, and the error is controlled within 0.1 seconds, which significantly improves the coordination efficiency.

4. Safety Redundancy Design ModuleStandard dual brake system and overload protection device, brake response time ≤ 0.2 seconds. In the mining scenario, the safety factor has been increased to 1.5 times the industry average by adding an anti-fall device and an emergency stop button.

3. Case Dismantling: Customized Landing Practice of a Mine Project

1. Project Background: Customers need to hoist ore in a shaft with a depth of 300 meters. The equipment is required to have explosion-proof performance, support frequency conversion and speed regulation, and the volume is not more than 2m. Traditional equipment cannot meet the demand due to excessive size or insufficient power.

2. Technical Solution：

-Motor selection: YBX3 series explosion-proof motor with 45kW power, suitable for -20 ℃ to 40 ℃ environment;

-Drum design: the diameter is reduced to 800mm, and the rope capacity is increased by increasing the number of winding layers;

-Control system: integrated frequency converter and encoder to realize 0.5-10 m/min stepless speed regulation;

-Safety configuration: equipped with dual hydraulic brakes and overload limiter, braking distance ≤ 0.5m.

3. Implementation effect: The equipment has been running for 12 months without failure, and the energy consumption is 18% lower than that of similar products. The customer will subsequently order 8 additional units for other mining areas.

Summary of 4. technical advantages

The customized technology system of Zhengzhou Rongjing Machinery Equipment Co., Ltd. has three core advantages:

1. Full process response capabilityIt only takes 15-30 working days from demand communication to delivery, which is 40% shorter than the industry average cycle;

2. Modular Design Platform: Reduce customization costs by quickly combining standardized component libraries (e. g., more than 200 reel specifications, 30 motor models);

3. Full Lifecycle Services: Provide free installation and commissioning, annual inspection and quick supply of spare parts, with a customer re-purchase rate of over 65%.
