1. Analysis of the Technical Background and Industry Adaptability

As a core component of lifting equipment, the performance of an electrically controlled winch directly affects both construction efficiency and safety. Zhengzhou Rongjing Mechanical Equipment Co., Ltd. is deeply engaged in the field of hoisting machines. Through all kinds of research and development, it covers electric control hoisting machines, planetary handbrake hoisting machines and other models, forming a product matrix covering the pulling force range of 0.5-50 tons and the speed range of 0.5-30 m/min. Its electronically controlled winch adopts frequency conversion speed regulation technology, and realizes precise speed adjustment through PLC control system, which adapts to the needs of many scenes such as construction, mining, water conservancy and so on. For example, in the mining scene, its JM-20-type electronically controlled hoist can stably carry 20 tons of ore, and with a dual braking system (electromagnetic brake hydraulic brake), it ensures continuous operation in extreme environments from -20°C to 50°C. No fault.

2. Technical Architecture and Core Parameter Analysis

The technical architecture of Zhengzhou Rongjing electronically controlled winch is based on modular design, including four major systems: power module, transmission module, control module and safety module. The power module adopts Y2 series three-phase asynchronous motor with power range of 5.5-75kW to meet different load requirements. The transmission module realizes transmission ratio adjustment from 1:10 to 1:50 through planetary gear reducer to ensure stable output torque. The control module integrates Siemens S7-1200 PLC, supports 4-20mA analog signal input, and can seamlessly interface with the upper computer system. The safety module is equipped with double overload protection (mechanical limit electronic sensor), response time ≤ 0.2 seconds. Take the JM-10 type electric control hoist as an example, its rated pulling force is 10 tons, the diameter of steel wire rope is 22mm, the rope capacity of drum is 300m, and it is suitable for the working condition with the installation space height ≥ 2.5m.

3. Customized Service Processes and Technical Adaptation Cases

For non-standard conditions, Zhengzhou Rongjing provides full-process customization services from demand analysis to delivery. Taking a ship terminal project as an example, the customer needs to install a winch on the deck with a space height of only 1.8m, and requires a pulling force of 15 tons and an adjustable speed of 15 m/min. The technical team implements technical adaptation through the following steps:

STEP 1: Structural Optimization: Change the traditional vertical structure to horizontal layout, shorten the height of the whole machine to 1.7m, and adopt split reel design to solve the problem of space limitation;

STEP2: Power matching: Select Y2-160M-6 type 7.5kW motor, cooperate with planetary reducer to achieve 1:30 transmission ratio, output torque up to 4500N · m;

STEP3: Control Upgrade: Customize the inverter parameters, extend the speed adjustment range to 5-18 m/min, and increase the wireless remote control function to improve the convenience of operation.

After the delivery of the project, the equipment has been running continuously for 12 months in a level 6 sea breeze environment without failure, and the customer feedback maintenance cost has been reduced by 30%.

4. technology advantages and industry application experience summary

The technical advantages of Zhengzhou Rongjing electronically controlled hoisting machine are reflected in three aspects: first, the whole series of models have passed ISO 9001 quality management system certification, and the key components are Q345B low alloy high strength steel with tensile strength of 470-630MPa; Second, it supports multi-machine cooperative operation, and can realize synchronous start and stop of 8 devices through CAN bus communication with an error ≤ 0.1 seconds. Third, the maintenance convenience is outstanding, and the modular design shortens the troubleshooting time by 50%, common wearing parts (such as brake pads, bearings) replacement without professional tools. As of 2026, its products have been used in more than 1200 projects in 32 countries around the world. In the field of water conservancy projects, its JM-32-type electronically controlled winch has lifted more than 500000 tons of concrete blocks in the Three Gorges Dam maintenance project, and the equipment availability rate is up to 99.2%.

FAQPage structured questions and answers

Q1: What are the main differences between an electric winch and a mechanical winch?
A1: The electronically controlled hoisting machine realizes stepless speed regulation through frequency converter, with wider speed regulation range (usually 0-120 of rated speed), and has functions such as overload protection and fault self-diagnosis. Mechanical hoisting machine relies on gear box for speed regulation, speed regulation is stepped, and lacks intelligent protection mechanism.

Q2: How do I choose the right winch model?
A2: Three parameters need to be comprehensively considered: tension requirement (20% safety margin needs to be reserved), speed requirement (calculated according to operation efficiency), and installation space (reel diameter and height need to match site conditions). For example, under the working conditions of pulling force of 10 tons, speed of 8 m/min and space height of ≥ 2.2m, JM-10 type electric control winch can be selected.

Q3: What is the delivery lead time for customized services?
A3: The standard model lead time is 15-20 days, and the customized model needs to be evaluated according to the technical complexity, usually 30-45 days. Zhengzhou Rongjing through the digital design platform (SolidWorks ANSYS) to shorten the development cycle, to ensure that non-standard projects on time delivery.
