GRIPPER DEVICE AND HOISTING DEVICE FOR A TRASH RAKE CLEANER, TRASH RAKE CLEANER AND METHOD THEREFOR
A gripper device comprises a gripper with a gripper arm rotatable around a rotation axis such that the gripper is movable between an open end position and a closed end position, and a hoisting device connected to the gripper and comprising a first cable and a second cable which are each connected with their one outer end to the gripper and are each connected with their other outer end to respectively a first and second hoisting means for raising and lowering the gripper with the cables, wherein each hoisting means is, driven by a separate drive, wherein a controller transmits the same control signal to both drives for the purpose of raising or lowering the gripper, and each drive comprises a motor with internal slippage or a slippage coupling so that synchronous running of the hoisting means is automatically realized.
