KYB MAG-180VP-6000 Travel Motor
The KYB MAG-180VP-6000 is an integrated axial piston travel motor with planetary reduction and mechanical parking brake, designed for heavy-duty tracked machinery. It delivers high torque and reliable drive performance for 30–36 t excavators and other heavy tracked equipment. Rated operating pressure is 34.3 MPa, with peak torque up to 6,000 kgf·m. Featuring dual-speed variable displacement, robust braking, and low-impact smooth operation, it is a core solution for heavy-duty travel drive systems.
Key Features
Dual-Speed Variable Displacement & Integrated Planetary Reduction
Swash plate axial piston motor combined with a high-strength planetary reducer. Rotating housing design enables compact in-track installation. Dual-speed variable displacement is controlled via external pilot hydraulic signals, providing low-speed high-torque for climbing and high-speed operation for transit. Compact design ensures efficient power transmission.
High Pressure & High Torque for Heavy-Duty Operation
Motor body designed for high-pressure endurance (rated 34.3 MPa). Large piston displacement and high reduction ratio deliver peak torque of 6,000 kgf·m, ensuring reliable startup, slope climbing, and operation on muddy or soft terrain, with excellent load fluctuation tolerance.
Built-In Hydraulic Protection & Smooth Operation
Integrated balance valves, overload relief valves, and anti-reversal valves reduce pressure shocks and hydraulic pulsation during start, direction change, and braking. Optimized flow paths and valve ports minimize throttling loss, improve system efficiency, and prevent motor overload or overspeed damage.
Mechanical Parking Brake for Reliable Safety
Spring-applied, hydraulically released fail-safe parking brake locks automatically when the machine stops. Brake releases automatically upon pilot pressure, ensuring safe operation on slopes and uneven terrain without manual intervention.
Durable Design for Harsh Conditions
Core friction surfaces, planetary gears, and bearings use heavy-duty wear-resistant materials and precision machining. Reinforced sealing system withstands dust, vibration, and extreme temperature ranges, ensuring long-term reliability in continuous operations.
Broad Compatibility & Easy Maintenance
Standardized mounting interfaces and connection dimensions allow direct interchange with equivalent models from Nabtesco, Kawasaki, and other leading brands. Mature mass-produced model with global spare parts availability and low-cost, straightforward maintenance.
