Overview of NJ Series Crane Hydraulic Winch
1. Series Name: NJ Series (or understood as a simplification/variation of the DYNJ series, given the context of the conversation)
2. Application Areas:
• Widely used in marine engineering, construction, water conservancy projects, forestry, mining, docks, and other fields for material lifting or horizontal dragging operations.
• Specifically suitable for cranes as a key component for lifting and traction.
3. Main Components:
• Hydraulic Motor: Typically adopts low-speed or high-speed motors with high mechanical efficiency and large starting torque.
• Brake: Hydraulic normally closed multi-disk brake to ensure the winch can brake quickly and reliably when needed.
• Planetary Gearbox: Provides necessary reduction and torque amplification to adapt to different workloads.
• Drum: Used for winding wire ropes or other lifting media, with sufficient strength and rigidity.
• Frame and Support Structure: Supports the entire winch unit, ensuring stability and durability.
4. Performance Characteristics:
• Compact Structure: The overall design is compact, with a small volume and light weight, facilitating installation and maintenance.
• Efficient and Safe: The hydraulic transmission system is efficient and safe, effectively preventing overload and secondary slipping.
• Easy Operation: Infinite variable speed control from zero to maximum speed can be achieved, with easy reversing and flexible operation.
• Strong Adaptability: Can be customized according to user needs, such as equipping with different valve groups, clutches, and other options.
5. Model Examples:
• DYNJ20-15-13 Hydraulic Winch (or corresponding NJ series variant)
• DYNJ25-15-12 Hydraulic Winch
• DYNJ30-15-14 Hydraulic Winch
• The numbers in the model may represent specific technical parameters such as tensile force, drum diameter, gear ratio, etc., but the specific meaning needs to be determined according to the manufacturer's specifications.
