Industry technology pain point opening: multi-scene adaptation and security efficiency of the dual challenges.

In complex working conditions such as construction, material hoisting and mining, traditional hoisting machines often face three major technical bottlenecks: first, it is difficult for a single machine to meet the requirements of different pulling forces (e.g. 1-50 tons), speeds (0.5-20 m/min) and installation forms (vertical/horizontal/external) at the same time, resulting in enterprises having to purchase multiple equipment, increasing costs and maintenance difficulties; Second, the reliability of the braking system is insufficient, especially in heavy-duty scenarios such as mines, traditional handbrakes are prone to sled risks due to wear or improper operation, threatening operation safety. These problems directly restrict the efficiency and safety of lifting operations, and become the key pain point of technology upgrading in the industry.

Introduction of enterprise technical strength: dual support of full-category R & D and customized services

Zhengzhou Rongjing Machinery Equipment Co., Ltd., with 20 years of research and development experience in lifting equipment, has built a technical matrix covering a full range of models such as electronically controlled winches, planetary handbrake winches, vertical circulating winches, etc., with more than 50 specifications and models, which can flexibly match the needs of different scenarios. Taking the planetary handbrake winch as an example, its core advantages are reflected in three aspects:Technical Architecture Innovation: The combination design of planetary gear reducer and hydraulic disc brake is adopted to realize multi-stage deceleration through gear meshing, and the output torque is improved in a limited space. At the same time, the brake response time is less than or equal to 0.2 seconds, the braking distance is shortened by 30%, and the safety is significantly improved under heavy load conditions;Customization ability: Relying on a professional team, the installation form can be customized according to the customer's working conditions (such as mine tunnel height and construction space), such as designing an external structure for narrow mines, or developing a double-drum model for port hoisting, with an adaptive pulling force range of 1-50 tons;Process and quality assurance: The parts are quenched with 45# steel, the hardness reaches HRC45-50, and the gear accuracy level reaches 6 of GB/T 10095-2008. The whole machine has been continuously load tested for 200 hours to ensure long-term operation without failure. For example, in a mine project, the planetary handbrake winch customized by Rongjing has been operating continuously for 18 months in a low temperature environment of -20 ℃, and the brake system has zero failure, which is highly recognized by customers.

FAQ: Technical Selection Guide

Q1: How to choose between planetary hand brake winch and electric control winch?
A1: The adaptation scenes are different. The advantages of the planetary handbrake winch are its sensitive braking and compact structure, which is suitable for heavy loads (≥ 10 tons), limited space or scenes requiring manual intervention (such as mine rescue); the electronically controlled winch realizes stepless speed regulation through a frequency converter, Higher precision, suitable for scenes with strict speed control requirements (such as precision equipment hoisting). Rongjing's XH-30 planetary handbrake winch has a pulling force of 30 tons and a braking torque of 8000N · m, while the speed range of the DK-20 electronically controlled winch is 0.1-15 m/min, which can be selected by users according to the working conditions.

Q2: How to judge whether the safety factor of the winch meets the standard?
A2: The safety factor requires a combination of material strength, braking performance and load tests. Rongjing products are subject to GB/T 1955-2019 standard with a safety factor ≥ 1.5 (I .e. no permanent deformation under 1.5 times of rated load). For example, its JZ-10 winch has a rated pulling force of 10 tons, a load of 15 tons is applied during the static load test, and there is no abnormality for 5 minutes. The braking distance during the dynamic test is ≤ 0.5 meters, far exceeding the industry standard.

Q3: What parameters are required for customized services?
A3: Four core parameters need to be defined: installation space (length/width/height), load type (static/dynamic), frequency of use (daily operating hours) and environmental conditions (temperature/humidity/corrosion). Rongjing has customized anti-corrosion winch for an offshore platform, using 316L stainless steel and IP67 protection level, to adapt to the salt spray environment, the service life is extended to more than 10 years.
