KYB MAG-170VP Traveling Motor Assembly: Detailed Specification
Core Positioning & Technical Characteristics
• Brand & Model: Manufactured by Japan's KYB (a specialist in hydraulic equipment/deck winches), part of the "MAG Series" traveling motor assembly family. Specific models include MAG-170VP-2400/3000/5000-10, featuring dual-speed capability (switchable high/low torque modes).
• Key Parameters:
• Power: 90,000W (rated), torque 45,000Nm, displacement 270cc, operating pressure 34MPa, weight 410kg.
• Medium & Load: Compatible with hydraulic oil, designed to withstand combined axial/radial loads, suitable for high-pressure environments (30-34MPa).
• Dual-Speed Functionality: Achieves high/low-speed switching via built-in dual-speed valves or external control modules, adapting to diverse operating conditions (e.g., low-speed high-torque for climbing, high-speed low-torque for flat-terrain movement).
Application Scenarios & Equipment Compatibility
• Construction Machinery:
• Excavators: Compatible with models such as Volvo 210, Sumitomo SH240, Case CX210, Sany 360, Zoomlion 360, serving as the core drive unit for tracked movement.
• Rotary Drilling Rigs/Marine Equipment: Used in rotary drill powerheads, marine winches, cranes (e.g., MAG-230VP-5000), supporting high-torque output.
• Cranes & Special Vehicles: Fits models like LiuGong 360, Yuchai 360, and engineering vehicles/tow trucks requiring hydraulic winches.
• Specialized Environments:
• Marine deck winches, down-the-hole drills, mining machinery (e.g., road rollers), and industrial winches requiring low-speed high-torque performance.
Structural Integration & System Design
• Assembly Components: Includes hydraulic motor body, reduction gear (e.g., MAG-230VP-3600), drive shaft, brake module (optional), dual-speed control valve, and shuttle valve.
• Installation Compatibility:
• Dimensions: Mounting hole sizes must match equipment specifications (e.g., Sumitomo 360 uses 18×26mm holes), requiring reference to device manuals.
• Interfaces: Hydraulic oil ports and electrical control interfaces (e.g., 24V relay modules) must align with the host system's hydraulic circuit.
• Hydraulic System Requirements:
• Requires high-pressure hydraulic circuits (≥30MPa) paired with proportional speed control valves and pressure sensors for precise operation.
• Certain models need external dual-speed valves (e.g., VPC-WTL5) or electronic control units (ECUs) for gear shifting.
Performance Advantages & Industry Standing
• Technical Highlights: KYB's patented dual-speed hydraulic five-star motor design, integrated with planetary gear reduction mechanisms, ensures high efficiency and low wear.
• Reliability: Utilizes wear-resistant alloy materials (e.g., QPQ surface hardening technology) for operation in harsh conditions (high temperature, dust, heavy loads).
• Market Recognition: Widely adopted by Japanese, European, American, and Chinese construction machinery brands, regarded as a premium alternative to imported hydraulic motors, particularly dominating excavator travel drive systems.
Critical Considerations
• Model Variants: Suffixes (-2400/-3000/-5000) denote variations in displacement and torque characteristics; selection must align with equipment power requirements.
• Maintenance Requirements: Regular checks for hydraulic oil cleanliness and seal wear are essential to prevent motor failures caused by contamination.
• Parts Compatibility: Replacement/repair parts (e.g., reduction gears, control valves) must be genuine or compatible models to maintain performance and safety standards.
