Product details
I. Product Overview
TheIYJ Series General Hydraulic Winchesare patented products independently developed byYining Hydraulic Co., Ltd.Featuring an integrated design, they combine core components such as a valve block (incorporating a one-way balancing valve and a high-pressure shuttle valve for brake control), a hydraulic motor, a brake, a planetary gear reducer, a drum, a frame, and a clutch. Users only need to equip a hydraulic power unit and directional control valve to complete system setup, significantly simplifying external hydraulic piping while enhancing the reliability of the transmission system.

II. Technical Features
1. High Efficiency & Energy Savings
• Delivers high efficiency during startup and operation with superior power density, consuming significantly less energy than traditional winches.
• The integrated valve block reduces hydraulic system pressure losses, further lowering energy consumption.
2. Compact Structure
• Modular layout ensures a small footprint and lightweight design, facilitating installation in space-constrained environments.
• Example: TheIYJ-N Series Internal Hydraulic Winchesintegrate the motor, brake, and reducer inside the drum, reducing length by over 30%.
3. Smooth Operation
• Matched planetary gear reducer and hydraulic motor ensure stable low-speed performance, minimizing vibration and noise.
• Typical noise levels are below75 dB(A), meeting industrial noise control standards.
4. Safety & Reliability
• Equipped with aZ-type hydraulic normally closed multi-disc brake, providing high braking torque and rapid response to secure loads.
• Integrated safety devices such as balancing valves and overload valves prevent load slippage or system overpressure.
5. Easy Maintenance
• Open structure simplifies routine inspections and upkeep. Standardized critical components (e.g., bearings, seals) offer long replacement intervals and low costs.

III. Key Parameters & Model Selection
1. Model Naming Convention
• Example:IYJ334-75-88-22-ZPG
• 334: Planetary gear reducer module numbers (3, 3, 4 for three stages).
• 75: Rated pulling force of 75 kN for the first rope layer.
• 88: Rope capacity of 88 meters.
• 22: Wire rope diameter of 22 mm.
• ZPG: Configuration with multi-disc brake and one-way balancing valve.
2. Critical Performance Metrics
• Total Displacement: Oil supply volume per drum revolution (mL/r), determining system flow requirements.
• Oil Supply Flow: Theoretical pump flow (L/min), accounting for volumetric efficiency (90–94%).
• Rope Capacity: Theoretical value must reserve 3 safety rope turns to prevent rope end detachment.
• Operating Pressure Differential: Pressure difference between hydraulic motor inlet and outlet (MPa), affecting output torque.
3. Selection Guidelines
• Choose models based on load weight, lifting height, and operating frequency.
• Example:IYJ22-20-55-10-ZPNDsuits light-duty applications with 20 kN rated pulling force and 55 m rope capacity.

IV. Applications
1. Construction Engineering: Material lifting, equipment installation, aerial work platforms.
2. Oil & Gas: Drilling rig hoisting, workover operations, pipeline laying.
3. Mining Machinery: Mine shaft lifting, open-pit mining equipment traction.
4. Marine Deck: Anchor winches, mooring systems, lifeboat deployment.
5. Geological Exploration: Drill rig feed, core sampling.

V. Derivative Models & Extended Functions
1. IYJ-L Series Free-Fall Hydraulic Winches
• Adds free-fall functionality for rapid load lowering (e.g., rescue equipment).
2. IYJ-ZZ Series Dual-Brake Personnel-Carrying Hydraulic Winches
• Features dual braking systems to meet personnel safety standards (e.g., construction hoists, aerial work vehicles).
3. ISYJ(HW) Series Vehicle-Mounted Hydraulic Winches
• Designed for vehicles like off-road trucks and military vehicles for self-recovery or towing.
4. I*J Series Mooring Winches
• Complies withGB4446-84standards for ship mooring, equipped with constant tension (CT) control.
5. Optional Accessories
• Rope guides, anti-rope-detachment alarms, rope aligners, speed measurement shafts, clutches, etc., customizable per application.
