Description

Can be hung on the crane

The invention relates to a spreader, and more particularly to a spreader that can be hung on a crane.

The applicant's spare crane suction cup was originally stored in the position where the sky crane was easy to be lifted. After the scene space was insufficient and the spare crane suction cup was easily damaged by the steel plate accidentally dropped during the lifting, the plan was to store the crane suction cup. The position is moved to the marginal area of the plant. However, this area is not the ability of the existing cranes and can not be directly hoisted, and the stacker is not readily available, which causes the trouble of selecting the storage location of the spare trolley suction cup.

In view of this, there is a need to propose a solution to solve the above problems.

It is an object of the present invention to provide a spreader that can be hung from a crane.

In order to achieve the above object, the spreader for hanging on a crane of the present invention comprises: a boom; at least one first sling is attached to the boom for pulling up the boom; at least one second crane a cable attached to the boom for pulling up a weight; and at least one weight member movably disposed on the boom, wherein the weight is when the boom pulls the weight Used to balance the boom.

According to the present invention, the spreader can be hung on a crane, wherein the boom is fastened with at least one lifting lug, and the first sling is tied to the lifting lug.

According to the present invention, a spreader that can be hung on a crane, wherein the first sling is locked to the lifting lug with a buckle.

According to the present invention, a spreader that can be hung on a crane, wherein the weight is fixed to the boom by a bolt.

According to the present invention, the crane can be hung on a crane, wherein the weight has a hollow structure and is sleeved on the hanger.

According to the present invention, the spreader that can be hung on the crane, wherein the system includes two first The sling is attached to the boom.

The spreader that can be hung from a crane according to the present invention includes two second slings attached to the boom.

According to the present invention, the crane can be hung on a crane, wherein the first sling is used to hang on the hook of a one-day vehicle.

According to the spreader of the crane which can be hung on the crane, the operator can quickly and easily use the crane to lift the assembled special tool on the steel cable to shorten the preparation time. When storing heavy objects, the operator can use the mobile counterweight to adjust the tilt angle of the boom, so that the driver can safely and smoothly move the crane and lift the heavy object to the proper position. In addition, when the heavy object is hung, the side of the heavy object can be lifted by the angle iron to make the sling naturally loose, and the bolt on the heavy object can be easily taken out, and the crane can be safely and quickly removed.

The above and other objects, features, and advantages of the present invention will become more apparent from the accompanying drawings. In the description of the present invention, the same components are denoted by the same reference numerals and will be described.

Figure 2 is a schematic view of the weight of the hanger of the crane of the present invention.

Figure 3 shows the use of the spreader of the present invention that can be hung from a crane to lift a heavy object.

Referring to Figures 1 and 2, the spreader 100 of the present invention can be suspended from a crane. The utility model comprises a hollow boom 110, which is provided with two lifting ears 112. At least one end of the hanging rod 110 is also suspended, for example. It is two slings 120. The spreader 100 also includes at least one hollow weight 130 that can be placed over the boom 110. When the weight 130 is placed over the boom 110, the latch 140 can be inserted into the pin hole 114 of the boom 110, thereby restricting the movement of the weight 130.

Referring to Fig. 3, when the spreader 100 of the present invention is used to lift a heavy object, one end of the sling 180 is locked with a buckle 182 to the lifting lug 112 of the boom 110 to which the weight 130 is assembled. On the other hand, the other end of the sling 180 is hung on the hook of the crane (not shown). Then, the crane is operated, the boom 110 is lifted, moved to the position of the weight 190 to be lifted, and the position of the weight 130 is appropriately adjusted, and then the weight 190 is attached to the sling 120 (please See Figure 4). When the weight 190 is hung, the crane can be operated to move the weight 190 to the appropriate place.

According to the present invention, the crane 100 can be hung from the crane, wherein the weight 130 functions to balance the boom 110 to prevent the boom 110 from being excessively tilted after the weight 190 is lifted. Therefore, as the weight of the weight 190 is larger, the position of the weight 130 is farther away from the weight 190 to maintain the balance of the boom 110. In addition, the weight and quantity of the weight 130 can be adjusted according to actual use conditions.

According to the present invention, the crane 100 can be hung from a crane, wherein the slings 120, 180 can be steel cables or chains, and are basically capable of withstanding the weight of the weight 190 and the boom 110.

According to the spreader of the crane which can be hung on the crane, the operator can quickly and easily use the crane to lift the assembled special tool on the steel cable to shorten the preparation time. When storing heavy objects, the operator can use the mobile counterweight to adjust the tilt angle of the boom, so that the driver can safely and smoothly move the crane and lift the heavy object to the proper position. In addition, when the heavy object is hung, the side of the heavy object can be lifted by the angle iron to make the sling naturally loose, and the bolt on the heavy object can be easily taken out, and the crane can be safely and quickly removed.

While the present invention has been disclosed by the foregoing examples, it is not intended to be construed as limiting the scope of the invention, and the invention may be modified and modified without departing from the spirit and scope of the invention. Therefore, the scope of the invention is defined by the scope of the appended claims.
