PROBLEM TO BE SOLVED: To provide a multi-joint front with a crane function which has a configuration advantageous in terms of lifting height and speed not only in cargo handling operation to the underground but in unloading and loading operation from a truck.SOLUTION: A multi-joint front with a crane function comprises: a sheave 21 which is mounted to a tip part 16 and hooks a wire rope 19 to be wound and delivered by a winch; and a hook block 23 which is supported by the wire rope 19 suspended from the sheave 21. The tip arm 16 comprises a connection part 36 for connecting the hook block 23 detachably. By the hoisting of the hook block 23 by the winch, the hoisting and lowering of the hook block 23 is performed. As another cargo handling form, the hook block 23 is connected to the connection part 36 provided in the tip arm 16, thereby enabling cargo handling operation by the actuation of the multi-joint front. |
