Technical Positioning and Full Scene Adaptation Capability of 1. Electronically Controlled winch

As the core model in the field of lifting equipment, the technical positioning of the electronically controlled hoist needs to take into account the power output, control accuracy and scene adaptability. Zhengzhou Rongjing Mechanical Equipment Co., Ltd. has covered the technical parameters of the electronically controlled hoist to three dimensions: pulling force range of 0.5-50 tons, operating speed of 0.5-20 m/min and installation form (vertical/horizontal/suspended) through a full-category research and development strategy, forming a standardized product matrix that can match 12 types of working conditions such as construction, mining and water conservancy projects. For example, in the mining scene, the electronically controlled hoist adopts a dual brake system design, and the braking torque reaches 1.5 times of the rated torque. With IP55 protection grade motor, it can adapt to extreme environments from -30 ℃ to 50 ℃ to ensure continuous operation stability.

Core Parameters and Implementation Path of 2. Customization Technology

According to the requirements of non-standard working conditions, Zhengzhou Rongjing's customized technical system includes three core parameter modules: space adaptation parameters (compact reducer is used when installation height is ≤ 3m, axial dimension is shortened by 40%), control parameters (PLC/frequency converter/wireless remote control is supported, response time is ≤ 0.2s), and safety parameters (overload protection device is equipped, and automatic shutdown is performed when rated load is 110). Taking a ship terminal project as an example, the customer requires the hoist to realize the dual functions of vertical lifting and horizontal traction in a narrow space. The technical team integrates the motor and reducer into a cylinder with a diameter of 400mm through modular design, and cooperates with the rotatable hook. The final product volume is 35% smaller than that of the standard model, while meeting the requirements of 10 tons of pulling force and 5 m/min speed.

Technical Support of 3. Material Technology and Quality Inspection System

In the manufacturing process, Zhengzhou Rongjing uses Q345B low alloy high strength structural steel as the main material, and its yield strength reaches 345MPa, which is 20% higher than that of ordinary carbon steel. The gear machining accuracy reaches the Grade 6 standard of GB/T 10095-2008, and the tooth surface roughness Ra≤ 0.8 μm, ensuring the transmission efficiency ≥ 95%. The quality inspection process covers 7 major links from parts to the whole machine: raw material spectral analysis, heat treatment hardness detection, gear meshing test, no-load operation test, load dynamic monitoring, braking performance verification, and salt spray corrosion test. Take the brake as an example, each product needs to pass 100000 fatigue tests, and the brake pad wear is less than or equal to 0.5mm to ensure long-term safety.

4. technology layout of the industry application experience review

By serving 3000 + customers around the world, Zhengzhou Rongjing has accumulated three major technical layout experiences: first, in the field of construction, a double-drum electric-controlled hoist has been developed according to the matching requirements of tower cranes, and the synchronous lifting of double ropes is realized through the design of synchronous shafts, with the error controlled within ± 5mm; Second, in water conservancy projects, in order to solve the sealing problem in sediment environment, a double lip sealing ring structure is adopted with a regular lubrication system, the bearing life is extended to 20000 hours; Third, in the material hoisting scene, the starting current is limited to 1.5 times of the rated current through frequency conversion speed regulation technology, which saves 30% energy compared with traditional resistance speed regulation. These technical parameters are tested and certified by third-party institutions, forming quantifiable technical advantages.
