Hydraulic rotator GRI series

Hydraulic continuous rotators for truck cranes and excavators. A really complete line. Idrobenne gear motors provide precision positioning of devices attached to truck loading cranes and excavators. These motors are the standard slewing gears for all ancillary equipment – whether these are orange peel grabs or polyp grabs, clamshell buckets, log grapples, etc. They’re available in more than 30 versions to suit a very large range of applications. State of the art design. The design-dependent braking effect when releasing pressure provides precise control. Proven gear motor drives provide constant, high torque and stable, low rpm even at high oil temperatures. A strong shaft and two tapered roller bearings absorb the axial and transverse loads produced in the most severe loading conditions. Powerful torque and stable rpm’s adapted to the application are the main characteristics of the carefully designed drive, based on the Gerotor principle. Continuous rotation. The unlimited turning angle and controlled pressure relief valves ensure that Idrobenne gear motors harmonise to the torque and braking moments demanded by the load.
