Abstract

Disclosed herein is a work implement for a machine designed to grip material or an object, the work implement comprising a frame (6), a first gripper component (2) and a second gripper component (4), a master actuator (10) having a first master port (40) on a piston side and a second master port (42) on a rod side and a slave actuator (12) having a first slave port (44) on a piston side and a second slave port (46) on a rod side and a hydraulic arrangement (8, 8'), the first gripper component (2) being coupled to the frame (6) in a pivotable manner, the second gripper component (4) being coupled to the frame (6) in a pivotable manner, the master actuator (10) being coupled to the frame (6) and the first gripper component (2) for pivoting the first gripper component (2) from an open position (36) to a closed position (38) and back. The slave actuator (12) is coupled to the frame (6) and the second gripper component (4) for pivoting the second gripper component (4) from an open position (36) to a closed position (38) and back. The hydraulic arrangement (8, 8') comprises a first side (28), a second side (30) and hydraulic conduits (26) for interconnecting the first side (28) to the first master port (40) and the second master port (42), the first slave port (44) and the second slave port (46) and the second side (30). The hydraulic arrangement further comprises a first pressure relief valve (18) having a first relief pressure (p1 ) and a second pressure relief valve (20) having a second relief pressure (p2). The master actuator (10) and the first pressure relief valve (18) are coupled in parallel, the slave actuator (12) and the second pressure relief valve (20) are coupled in parallel and the master actuator (10) and the first pressure relief valve (18) are coupled in series with the slave actuator (12) and the second pressure relief valve (20), whereby the first pressure relief valve (18) and the second pressure relief valve (20) are arranged to open up in a same direction either from the first side (28) to the second side (30) or from the second side (30) to the first side (28).
