2066600 9201612 PCTABS00010 The bin grabbing nipper (22) of a refuse loader arm is held at a constant angle to limb (15) by a parallelogram linkage having pivots (26, 17, 19, 25). Thus, pivotting of limb (15) leads directly to inversion of the raised bin and no separate operation of a special bin tilting ram is required to bring a bin to dumping position. The nipper consists of two opposed, jointed fingers which are separately pivotted to a wrist member (21). All finger joints and wrist joints of the nipper are pivotted by separate hydraulic cylinders supplied by a common source. By sensing back-pressure in each cylinder they can be made to exert equal force. Pivotting at limb joints (17) and (19) is by opposed hydraulic cylinders acting on a rack meshing with a gear wheel. Both these joints may be controlled by a single joystick.
