Abstract
A crane includes: a machine body; a tiltable body having a tiltable body proximal end supported on the machine body and being turnable in a tilting direction; a counterweight; a base weight having a placement surface that allows placement of the counterweight and being detachably attached to the machine body in either at least a front position or a rear position located behind the front position with the base weight projecting rearward further from the machine body than in the front position; and an auxiliary coupling member for coupling a portion of the base weight located in the rear position and the machine body to each other, the portion projecting rearward from the machine body.
Claims7
A crane comprising:
- a machine body;
- a tiltable body having a tiltable body proximal end supported on the machine body and being turnable in a tilting direction;
- a counterweight;
- a base weight having a placement surface that allows placement of the counterweight and being selectably attachable to the machine body in both;
- a front position and a rear position located behind the front position with the base weight projecting rearward further from the machine body than in the front position, when attached the base weight is located below the machine body in the front position and the rear position;
- and
- an auxiliary coupling member for coupling a portion of the base weight located in the rear position and the machine body to each other, the portion being located below and projecting rearward from the machine body.
A crane comprising:
- a machine body:
- a tiltable body having a tiltable body proximal end supported on the machine body and being turnable in a tilting direction:
- a counterweight:
- a base weight having a placement surface that allows placement of the counterweight and being selectably attachable to the machine body in both a front position and a rear position located behind the front position with the base weight projecting rearward further from the machine body than in the front position;
- and
- an auxiliary coupling member for coupling a portion of the base weight located in the rear position and the machine body to each other, the portion projecting rearward from the machine body, wherein
- the machine body includes
- a frame,
- a plurality of pairs of frame coupling portions provided on the frame behind the tiltable body, the pairs of frame coupling portions including a pair of right and left frame front coupling portions and a pair of right and left frame rear coupling portions provided behind the pair of right and left frame front coupling portions, and
- a frame auxiliary coupling portion provided on a rear end portion of the frame, the base weight includes
- a pair of right and left weight front coupling portions that is selectively coupled to one of the pair of right and left frame front coupling portions and the pair of right and left frame rear coupling portions, and
- a pair of right and left weight rear coupling portions that is located behind the pair of right and left weight front coupling portions so as to be couplable to the pair of right and left frame rear coupling portions in a front coupling state where the pair of right and left weight front coupling portions is coupled to the pair of right and left frame front coupling portions, and is located behind the frame in a rear coupling state where the pair of right and left weight front coupling portions is coupled to the pair of right and left frame rear coupling portions, and
- the auxiliary coupling member is for coupling the frame auxiliary coupling portion and the pair of right and left weight rear coupling portions to each other in the rear coupling state.
