Description of Lifting Process of Double Plate Lifting Clamp

- Apr 08, 2018-

In the process of using the double plate lifting clamp, the relative devices of the hinges of the toothed claws, the supporting plates, the pull rods and the small pull rods connected thereto are determined after trial and comparison by coordinate mapping and will directly determine the tooth jaws. The direction of the force and the size of the jaw travel.

 

When the object is dropped, the jaws of the double-plate lifting pliers should be removed from the grasped weight so that when the lifting clamp is lifted, clamping is performed again. When the double-plate lifting clamp lifts the thin plate, the rotation angle of the pull rod is larger, and the horizontal component force exerted by the heavy arm is also large, and the claws are strongly grasped.

 

When the double-plate lifting clamp lifts the thick plate, although the rotation angle of the pull rod is small, the horizontal force exerted by the heavy arm is small, but due to the leverage of the claw itself, the heavy object still has a strong grasping force. Therefore, the double-plate lifting pliers can work normally and reliably within the lifting range of 1-60 mm.

 

In fact, the double-plate lifting pliers can be used for lifting work in addition to lifting weights, such as pulling out a steel bar stuck in an iron shell. Other angle steels, I-beams, etc. that are pulled out of the building site are also applicable, making the whole process more convenient.

 

The small hook on the double plate lifting pliers shell can be used for not grasping the heavy object; and when the jaws are in the open state, when the heavy object is clamped into the jaws, the small hook is opened, and the lifting can be performed by lifting upwards; After the shipment is completed, hang the small hook and the crane can lift the tongs without manpower.

 

When the lifting plate is lifted by the double plate lifting clamp, it can be lifted horizontally and vertically, and it is better to insert the clamp completely. From the horizontal position to the vertical position, the claws gradually grasp the steel plate. When the steel plate is in the upright position, there is no danger of falling down, as the tongs will be gripped as soon as the center of gravity is exceeded.
