In addition, it has a structure that enables compact storage by removing a screwing part and an expansion / contraction adjustment mechanism that can be adjusted to a length that is easy to use according to the state of attachment and detachment of the gutter.

A lifting hook (5) for attaching / detaching a hanging bracket (6) is mounted on a front portion of the main frame (3), and a pair of wheels (4) are mounted on a lower portion. A support bar (5A) is fixed to the lifting hook (5).

[0010] A detachable mounting portion (6B) detachably attached to the lifting hook is fixed to one end of the two hanging metal frames (6C) of the lifting bracket (6). A hook claw (6D) for holding a heavy object is fixed to the other outer end. It has a mechanism that can adjust the width of the hanging bracket frame (6C) according to the length of the heavy object.

FIG. 2 shows an embodiment in which a hanging bracket (6) is attached to a bar-shaped lifting hook (5) facing upward, and a gutter cover is held.

FIG. 3 shows a hanging attachment for a narrow place (7).
Was inserted into the lifting hook (5), the hanging fitting (6) having the hook (6A) for attaching the one-touch clamp was attached via the connecting fitting (8), and the side groove lid was held by the hook claw (6D). It is an example.

FIG. 4 shows an embodiment in which the hook (6A) for the one-touch clamp device is lifted on the hook (5) and the groove cover on the hook side is unclamped.

FIG. 5 shows that the operation handle (1) is swung right and left to remove the hook (6A) for the one-touch clamp device from the lifting hook (5), and then the side groove cover is hooked to the hook claw (6).
This is an embodiment in which the clamp state is set in D).

FIG. 6 shows an embodiment which can be used not only as a lifting and moving device but also as a transporter by mounting an attachment of the transport receiver (9).

FIG. 7 shows an embodiment which can be used even when the work is difficult due to accumulation of sand, mud, etc. by mounting the crowbar attachment (10).

FIG. 8 shows an embodiment in which the burl attachment (10) is mounted and the side groove cover is detached. As described above, the present invention has been described with reference to the preferred embodiments.
The present invention is not limited to this embodiment, and it goes without saying that many modifications can be made without departing from the spirit of the invention.

[0018]

According to the present invention constructed as described above, the position of the operation handle (1) by the telescopic adjustment frame (2) can be adjusted to a position that is easy for the operator to work. Fatigue can be reduced.

Also, a hanging attachment for a narrow place (7)
By attaching a gutter, a gutter cover or the like can be attached or detached in accordance with a work place, and work in a narrow place, which was conventionally only possible by manual work, becomes possible.

At the time of attaching / detaching the side groove cover or the like, the clamp / unclamp of the suspension fitting (6) having the hook (6A) for the one-touch clamp device can be operated with one touch, can be easily moved, and the next operation can be quickly performed.

When attaching and detaching the gutter cover, etc., even if sand, mud, etc. are accumulated in a place where cleaning is not performed for a long time and the work is difficult due to clogging, a plurality of tools are not required and one-touch operation is possible. Can be used as a tool with a crowbar structure

Since it also has a transporting cart function, a plurality of operations
It is possible with a table.
