- Dec 18, 2018-

In the process of driving the load, the ratchet lever block mainly pulls the handle manually by means of manpower, and uses the principle of lever to obtain the linear traction force matched with the load, and rotates to act on a caliper body in the movement of the movement to realize the operation. . The lever hoist has the advantages of compact structure, light weight, small size, convenient and labor-saving, safe and reliable, long service life, small hand pulling force and small wear on the wire rope.

 

For the user, the lever hoist can be used for lifting, pulling, lowering and calibration. If used in conjunction with other special devices, it is also convenient to choose the appropriate operating position, or to expand the load capacity by a small tonnage machine. For larger tonnage loads, several tools can be used in parallel.

 

It should be noted that when using the hoist, you should select the appropriate size and no overload. Before use, the ratchet lever block should be checked for safety, and the hoist should be tested for no-load test. The position of the hook can be adjusted according to the actual requirements. After the adjustment is completed, the heavy object is hung in the middle position of the lower hook, and the lifting of the handle can realize the lifting of the heavy object.
