Lever hoists have a lot of advantages:without power resources, the products are small in size, light in weight and easy to carry.Therefore, it has not very high requirements for the workplace. It can be widely used in shipbuilding, transportation and other fields. In addition, safety problems, lever hoists also solved this problem well.
The lever hoist is a straight-line traction force that matches the load through the lever principle by the lever principle, and the rotated ground acts on a clamp body loaded in the core to drive the load operation. It has the advantages of compact structure, light weight, small size, convenient and convenient carrying, safe and reliable, long service life, small hand pulling force, small wear to wire rope and so on. It can carry out lifting, traction, descent, calibration and other operations. If a special device is configured, it can not only be a non linear traction operation, but also can easily select the appropriate operating position, or doubly expand its load capacity with a smaller tonnage machine. Several machines can be used in parallel operation for a large tonnage load.
Safety requirements for use:
(1) when using the lever hoist, the lifting capacity is not allowed to exceed the allowable load, and should be used according to the marked weight.
(2) the handle can not be used arbitrarily, because the weight of the lever hoist is limited and the force of the two hand wrenching also has a certain size. The lengthening handle will cause the overloading of the lever hoist, causing the parts to be damaged.
(3) hand pull gourd should be thoroughly checked and tested before use. After use, it should be maintained.
The safety and reliability of the lever hoist is worth affirming, plus the safe use method and the maintenance, it is believed that it can guarantee the safety of our work to a great extent.
