I. Technical Background: Industry Positioning and Customization Requirements of the Planetary Parking Brake Winch

Planetary刹停车卷扬机 as a high-end model in the winch field, its core advantage lies in achieving high torque output and precise braking through the planetary gear transmission structure, suitable for scenarios with stringent equipment stability requirements such as mining and water conservancy projects. Zhengzhou Rongjing Machinery Equipment Co., Ltd. (hereinafter referred to as "Rongjing Machinery") has been dedicated to the lifting equipment field for more than ten years, developed a full series of planetary刹停车卷扬 machines covering a tension range of 5-200 tons and supporting speed adjustment from 0.5-15m/min for different industrial working conditions, and realized rapid customized production through modular design.

Chapter 2: Key Elements of Customized Design Analysis

1. Transmission system optimizationRongjing Machinery adopts a three-stage planetary gear reducer structure, with a transmission ratio of up to 1:200. Combined with high-strength alloy steel gears, the load-bearing capacity is increased by 30% compared to traditional winches. Taking a mining project as an example, the customized 100-ton planetary handbrake winch has a gear wear rate of less than 0.02mm after continuous operation for 12 months, meeting the long-term high-load operation requirements.

2. Brake system upgrade：In response to harsh working conditions such as humidity and dust, Rongjing Machinery has developed a dual-circuit hydraulic braking system with braking torque up to 1.5 times the rated tensile force. Measured data shows that under full load, the braking distance is controlled within 0.3m, which is 40% shorter than the industry standard, effectively avoiding the risk of wheel slipping.

3. Modular designBy standardizing motor, reducer, drum, and other core components, Rongjing Machinery can quickly assemble different specifications of models. For example, a water conservancy project customer needed to install a winch in a narrow space. Rongjing Machinery successfully met the on-site installation requirements by shortening the drum length (standard type 1.2m→customized type 0.8m) and optimizing the motor layout.

三、操作案例：从需求到实施的全流程服务

Case BackgroundAn overseas mining company requires purchasing a set of planetary winches with a handbrake for ore lifting, which must be explosion-proof, suitable for -30℃ low-temperature environments, and have a single-unit tensile force of 150 tons.

Customized process：

STEP 1: Requirement AnalysisThe Rong Jing Mechanical Technology team conducted an on-site inspection and found that the customer's existing equipment had experienced multiple shutdowns due to a failure in the braking system, and the installation space was limited (height ≤ 3m).

STEP 2: Solution DesignFor explosion-proof requirements, select ExdIIBT4 explosion-proof motor; to adapt to low-temperature environments, use low-temperature grease (still operates normally at -40℃); through optimizing the planetary gear structure, compress the equipment height to 2.8m, while increasing the tensile force to 160 tons (with safety margin reserved).

STEP 3: Production and TestingDuring the production process, laser cutting, CNC machining, and other technologies are used to ensure precision. After the complete set assembly, a 72-hour continuous load test is conducted to simulate actual operating conditions such as startup, braking, and operation, ensuring a 99.9% failure-free rate.

STEP 4: Delivery and MaintenanceAfter equipment delivery, Rongjing Machinery provides a remote monitoring system that allows for real-time acquisition of equipment operation data (such as temperature, vibration, braking pressure, etc.) and preset alarm thresholds to anticipate potential malfunctions in advance.

Chapter 4: Technical Parameters and Compatibility Scenarios

Rongjing mechanical planetary handbrake winch core parameters are as follows:

• Traction range: 5-200 tons (extendable to 300 tons)
• Speed Range: 0.5-15m/min (Variable Frequency Speed Regulation)
• Braking Method: Hydraulic Disc Braking (Dual Circuit)
• Protection Grade: IP55 (Dustproof and Waterproof)
• Operating Temperature: -40℃ ~ +60℃

Application scenarios include: mining (ore lifting), water conservancy projects (gate opening and closing), construction (material hoisting), shipyards (cargo handling), etc. For example, in a port project, Rongjing Machinery's customized 80-ton planetary brake winch, by optimizing the drum diameter (increased from the standard 800mm to 1000mm), extended the lifespan of the wire rope from 6 months to 12 months, reducing the customer's maintenance cost by 40%.

Chapter 5: Summary of Technical Advantages
