Product Introduction
The GM2-2700 hydraulic motor is one of the hatch cover hydraulic motors used in bulk carriers, consisting of a gear reducer, hydraulic motor and control valve group. Displacement 2700cm3/r, rated pressure 210bar.
GM2-2700 hydraulic motor is a high-speed, high-torque axial piston hydraulic motor designed for industrial applications requiring efficient power transmission and precise control. Its high torque, fast response, and reliable performance provide efficient power solutions in heavy-duty industrial scenarios. It is an ideal alternative to traditional electric motors or low-speed motors which is commonly used in construction machinery, agricultural machinery, metallurgical machinery, and other fields.
GM2: Series designation (SAI crankshaft radial piston motor)
2700: Frame size, commonly named for marine hatch cover application
Full model often marked as GM2-2700R24; R24 means port arrangement, shaft and integrated brake valve assembly for ship hatch cover.
Inner five-star radial piston structure, fixed displacement, high starting torque, stable low-speed rotation.
Compact integrated design, most versions come with built-in brake and shuttle valve, specially designed for marine hatch cover opening/closing.
Strong anti-shock performance, suitable for marine harsh environment.
Multiple shaft, flange and port options available; aftermarket replacements are common.
Marine: ship hatch cover driving system (MacGregor hatch cover)
Heavy duty swing and winch drives on vessels
Fixed displacement only, no two-speed shift function, unlike HMC series.
The GM2-2700 with suffix R24 is the standard hatch cover version with integrated brake valve.
