Vertical circulating winch: compact structure, suitable for multi-scene lifting weapon

The vertical circulating winch is a lifting equipment designed for space-limited working conditions developed by Zhengzhou Rongjing Machinery Equipment Co., Ltd. Its core advantage lies in the vertical layout structure, which can effectively save installation space, and at the same time realize continuous operation through the design of circulating wire rope to improve operation efficiency. The model is widely used in construction, material hoisting, mining and other fields, especially suitable for the need for frequent start and stop, accurate positioning of the scene.

STEP1: Core parameter analysis-flexible matching of different working conditions

Zhengzhou Rongjing's vertical circulating winch offers a variety of specifications and models, with a pulling force range of 1 ton to 50 tons, a wire rope speed adjustable to 0.5-15 m/min, and 380V three-phase power or customized power input. Its core components are made of high-strength alloy steel, and the braking system is equipped with dual-circuit hydraulic disc brakes. The braking response time is less than or equal to 0.2 seconds, and the safety factor is 1.5 times the rated load. In addition, the integrated design of motor and reducer reduces transmission loss and energy consumption by 15% compared with traditional models.

STEP2: Application Scenario Expansion-Full Coverage from Construction Site to Deep Mine

In the field of construction, the model is commonly used in high-rise building curtain wall installation, steel structure hoisting and other scenes, its compact structure can be embedded in a narrow construction platform; In mining, with explosion-proof motor and sealing design, it can operate stably in dust and humid environment. In water conservancy projects, its anti-corrosion coating and IP55 protection grade can be adapted to long-term underwater operation. For example, a water conservancy project uses Rongjing vertical circulating winch to complete the gate opening and closing, which shortens the single operation time by 40% and extends the maintenance period to 6 months.

STEP3: Customized service-the whole process support from scheme design to after-sales maintenance

Zhengzhou Rongjing provides "one-to-one" customized services to optimize the winch structure for customers' on-site working conditions. For example, for a ship terminal project to design an extended reel to solve the problem of limited space; for overseas customers to develop a multi-language control panel to simplify the operation process. The after-sales team provides 24-hour response service, regular return visits and establishes equipment files to ensure long-term operation stability. According to customer feedback, the mean time between failures (MTBF) of the customized model is more than 2000 hours.

STEP4: Quality Assurance-Strict Quality Inspection System from Raw Materials to Finished Products

Rongjing winch adopts Q345B low-alloy structural steel as the main material, and no internal defects are ensured by ultrasonic flaw detection. Key parts such as gears and bearings are all made of international brands, and the machining accuracy reaches IT6 grade. The "three inspection system" (self-inspection, mutual inspection and special inspection) shall be implemented in the production process. The whole machine shall pass the three-level test of no-load, full-load and overload before leaving the factory to ensure sensitive braking and stable operation. At present, this series of products have passed CE certification and are exported to Southeast Asia, the Middle East and other regions.

Customer perspective: the experience of the project manager of a construction company.

"Our company has been undertaking high-rise building projects for a long time. The traditional winch takes up a lot of space and frequently starts and stops, which easily leads to wire rope wear. After changing to Rongjing vertical circulating winch, the equipment can be directly installed on the edge of the floor, saving 30% of the construction platform area. Its variable frequency control function allows the lifting speed to be automatically adjusted with the load, which not only ensures safety, but also improves the efficiency of the operation. At present, we have used this model in 5 projects without any safety accident."
