Toshiba SG20 MFB250 hydraulic motor specifications
Toshiba SG20 is a heavy-duty hydraulic gear motor designed to drive the slewing mechanisms of large quarry excavators. This unit is the pinnacle of engineering in its class, combining a large-volume axial piston motor and a massive planetary gearbox. Its key task is to create a colossal torque to rotate the multi-ton platform of the largest excavators, while ensuring accuracy, reliability and safety in the most difficult operating conditions.
Technical specifications of the Toshiba SG20 MFB250 hydraulic motor:
- Type: Hydraulic motor-reducer for platform rotation
- Design: It is a single monolithic unit consisting of:
- Hydraulic motor: Axial piston motor with swash plate, designed to operate with extremely high pressure and high flow rates of hydraulic fluid.
- Gearbox: Integrated multi-stage planetary gearbox with reinforced design for maximum torque transmission.
- Valve block: An integrated block containing safety and brake valves to protect against peak loads and ensure smooth braking.
- Displacement: 250 cm3/rev.
- Nominal working pressure: 320-350 bar (32 - 35 MPa).
- Maximum peak pressure: 400 bar (40 MPa).
- Output speed: 8-10 rpm (for example, for Kobelco SK480D the speed is 9.0 rpm).
- Weight: approximately 380-450 kg.
- Application: The SG20 gear motor is installed on heavy quarry excavators weighing from 45 to 55 tons.
Cross numbers of hydraulic motors: VOE14645001, VOE14625697, VOE14535293, VOE14622007, VOE14645005
Installed in the equipment model:
- Volvo EC360, EC700B
