Main advantages and scope of application of Nabtesco GM series hydraulic motors
The GM series from Nabtesco are compact hydraulic motors designed to drive slewing mechanisms and crawler running systems of construction equipment. They provide high reliability, smooth operation and efficient torque transmission under high load conditions. Due to their modular design and wide model range, the GM series is actively used in excavators, cranes, drilling and other mobile machines.
The main advantages of Nabtesco GM series hydraulic motors:
- Unified modular design
The hydraulic motor, gearbox, parking brake and hydraulic valves are assembled in one housing, which simplifies installation and reduces the need for additional external elements.
- High reliability in harsh conditions
GM series components withstand heavy loads, water hammer and operation at high pressure (up to 35 MPa), which ensures a long service life even in difficult operating conditions (construction, mining, road works).
- Two-speed operation mode
The presence of speed switching (Low/High speed) allows you to adapt the motor to different driving or turning modes - a convenience for equipment with variable load.
- Smooth and safe operation
Built-in counterbalance valves and shockless relief valves provide pressure control, reducing the risk of water hammer and ensuring safe braking.
- Wide model range
Models are available for equipment from 2 to 50+ tons, including mini excavators, standard construction machines and heavy quarry equipment.
- Easy service support
In many countries (including Ukraine), there is access to spare parts, repair kits, and service for the GM series, which reduces downtime.
- Optimal price-quality ratio
Nabtesco GM are engines that have proven themselves well among special equipment manufacturers (Hitachi, Komatsu, Doosan, etc.) due to their stable quality at a reasonable price.
Scope of application of Nabtesco GM motors: slewing drives, crawler drives (travel motors), winches and other special equipment - excavators, cranes, drilling rigs, road machines.
