When the forklift 7 uses one support shaft instead of the upper and lower horizontal members 11 and 12 for mounting a so-called fork, the locking portion 6 is formed as a hole through which the support shaft passes. It can be modified in various ways.

The fork portion 3 is, in this example, the side plates 19 and 19 having a small height and a long length, and the side plates 19 and 19.
It has a plurality of vertical connecting plates 27, 27 connecting the spaces at a right angle, thereby forming a long frame body 30 having a fork shape. Further, in order to withstand a large load, the side plates 19 of the long frame body 30 are connected by a support shaft 31A, and a large number of wheels 31 such as nylon rollers and urethane rollers for traveling are connected by the support shaft 31A. The upper edge does not protrude from the upper end of the side plate 19, and the lower edge of the wheel 31 protrudes from the lower end of the side plate 19 for pivotal attachment. Note that the fork portion 3 may have a length that is, for example, approximately the same as the length of the container C or even a length that exceeds the length of the container C for the convenience of loading and unloading the heavy work W. In this example, for example, 80-150 cm
The length is about the same as a normal fork. Further, the minimum height of the fork portion 3, that is, the upper surface height of the load receiving frame 5 at the lowered position is made as small as possible.

The wheels 31 may be caster wheels that can be turned around in a plane.

Further, the fork unit 3 includes a lifting drive 32.
Is installed. In this example, the lifting drive 32 is a hydraulic cylinder having a small stroke, for example, a stroke of about 30 to 50 mm, which is attached to each of the connecting plates 27, 27 and has a large lifting force, and the rod is fixed upward. .

The load receiving frame 5 is fixed to the rod end. The load receiving frame 5 is provided with side plates on both sides of a long strip-like horizontal and tapered upper plate 40 extending from the vicinity of the base portion 2 to the front end of the fork portion 3 on the long frame body 30 along the fork portion 3. 19 hanging pieces 41, 41 are provided along the outer surface. The load receiving frame 5 is fixed to the rod end of the lifting drive machine 32 by a mounting portion on the lower surface of the upper board 40, and the heavy work W on the upper board 40 is operated by the operation of the lifting drives 32, 32.
