STEP1: Understanding the core value of external variable frequency winch

External variable frequency hoist is a special lifting equipment developed by Zhengzhou Rongjing Machinery Equipment Co., Ltd. for construction, material hoisting, mining and other scenes. Its core advantage lies in the precise adjustment of tension and speed through frequency conversion technology, and with modular design, it can flexibly match the needs of different working conditions. For example, in water conservancy projects, the equipment can adapt to the lifting of the sediment mixture by adjusting the operating frequency, avoiding the jam or overload problems caused by the fixed parameters of the traditional winch.

STEP2: Full category coverage to meet diverse needs

Zhengzhou Rongjing Machinery Equipment Co., Ltd. provides a full range of models including external variable frequency winch, covering various types of electric control, planetary handbrake, vertical circulation, etc. Take a ship terminal project as an example, the customer needs to meet the needs of hoisting 5 tons of cargo and fast positioning at the same time, the company through customized configuration of external variable frequency models, the lifting speed will be increased to 12 m/min, at the same time through the dual brake system to ensure the safety of the operation, and finally achieve a daily operation volume of 30%.

STEP3: Personalized Customization Service: Full Process Support from Scheme to Landing

For special conditions, the company's technical team can provide "one-to-one" customized services. For example, a mining enterprise needs to install the winch on the side wall due to the narrow roadway space, and the traditional model cannot be adapted. By optimizing the transmission structure, reducing the volume of the equipment and adopting explosion-proof motors, the Rongjing team finally delivered the variable frequency winch not only to meet the space limitation, but also to adapt to the humid environment of the mine through IP55 protection grade, and to run for two years without failure.

STEP4: Quality assurance: strict control from raw materials to finished products

Rongjing winch adopts the main structure of high-strength alloy steel, with heat treatment process to improve wear resistance. Take a water conservancy project as an example, the equipment needs to be soaked in chlorine ion water for a long time, the company through the selection of 316L stainless steel material and special coating, so that the equipment in the corrosive environment still maintain stable performance, compared to the ordinary model life extension of 2 times. At the same time, each equipment must pass the static load test of 200% rated load and the dynamic load test of 120% before leaving the factory to ensure that the safety factor meets the standard.

STEP5: Service Upgrade: Full Cycle Support Reduces Customer Costs

In addition to the product itself, Rongjing provides full-process services from pre-sales consultation to after-sales maintenance. For example, an overseas customer encountered difficulties in the equipment debugging stage due to language and time difference problems. The company sends engineers to the scene within 48 hours through remote video guidance to quickly solve parameter setting problems and train local operators to avoid daily losses of more than 50000 yuan due to downtime. At present, the customer has ordered 10 additional devices of the same model.
