Description

A kind of from breaking off relations

[technical field]

The utility model relates to hoist tool technical field, especially relates to a kind of from breaking off relations.

[background technology]

Known, usually need when lift cargo to use hook, catch on hawser by hook goods is lifted, then the place of specifying is transported to, but present hook use very inconvenient, after goods handling to given place, need artificial the hawser of hook from goods to be got on, but when the goods of handling is very high, very large, or bad for goods handling to go to the place of hook time, people's strength that waste is very large when removing hook will being made like this, greatly reducing work efficiency.

[utility model content]

In order to overcome the deficiency in background technology, the utility model discloses a kind of from breaking off relations, the utility model passes through to arrange S. A. on upper boom, and arranges hook at upper boom two ends, reaches the object of hook Automatic-falling with this.

In order to realize described utility model object, the utility model adopts following technical scheme:

A kind of from breaking off relations, comprise upper boom, S. A. and hook, upper boom is provided with S. A., the two ends of upper boom are respectively equipped with hook.

Described S. A. is arranged on the middle part of upper boom.

Described upper boom is column type or prismatic structure, and upper boom bottom faces is arcuate structure.

The hook structure at described upper boom two ends is identical, at the hook of the quantity such as upper boom two ends are equipped with.

Owing to have employed technique scheme, the utility model has following beneficial effect:

One described in the utility model, from breaking off relations, comprising upper boom, S. A. and hook, by arranging S. A. on upper boom, and arranging hook at upper boom two ends, reaches the object of hook Automatic-falling with this; The utility model is practical, uses and installs all fairly simple, can lift goods very easily, and makes hook separate automatically after allocation and transportation are complete, thus facilitates daily transport.

[accompanying drawing explanation]

Fig. 1 is perspective view of the present utility model.

In figure: 1, upper boom; 2, S. A.; 3, link up with.

[detailed description of the invention]

By explanation the utility model that the following examples can be detailed, open the purpose of this utility model is intended to protect all technological improvements within the scope of the utility model.

One by reference to the accompanying drawings described in 1 is from breaking off relations, and comprise upper boom 1, S. A. 2 and hook 3, upper boom 1 is provided with S. A. 2, and the two ends of upper boom 1 are respectively equipped with hook 3; Described S. A. 2 is arranged on the middle part of upper boom 1; Described upper boom 1 is column type or prismatic structure, and upper boom 1 bottom faces is arcuate structure; Hook 3 structure at described upper boom 1 two ends is identical, at the hook 3 of the quantity such as upper boom 1 two ends are equipped with.

Implement one described in the utility model from breaking off relations, in use, first autospasy hook block is got up by the S. A. 2 above upper boom 1 by shackle and chain sling, because S. A. 2 is arranged on the middle part of upper boom 1, and the quantity and weight of upper boom 1 two ends hook 3 is identical, material is thus formed certainly breaking off relations of a weight balancing structure, and S. A. 2 is the equal of a pivot shaft, when allocation and transportation goods, first hang goods with the hook 3 of upper boom 1 one sections, and the hook 3 of upper boom 1 other end does not stress, after goods hangs and delivers to appointed place, goods is put on ground, then continue to decline from breaking off relations, like this under the principle of weight balancing, upper boom 1 is made to return to level attitude, such hook 3 is just buckled Automatic-falling got off from being unloaded, thus reach the effect of autospasy.

The non-detailed portion of the utility model is prior art.
