Chain block is suitable for production of factory, miners, agriculture, electric power, building, goods lifting, vehicle loading and unloading, etc. And lever hoist may be applied to any small, portable lifting device which relies on the manual operation to lift o lower heavy loads. Lever hoists fall into two main categories: cable or rope hoists and chain hoists.
A manual chain hoist is operated by hand when a chain loop on one side of the hoist housing unit is pulled down.
This turns a pulley mechanism of two gears lifting the other end of the chain, which has a hook on its end and attached to the load. Pulling down on the chain with the action of the two gears lifts the load. Hoists can be operated manually, electrically or pneumatically.
The term lever hoist may be applied to any small, portable lifting device which relies on the manual operation to lift lower heavy loads. Lever hoists fall into two main categories: cable or rope hoists and chain hoists. Both variants rely on a ratchet and pawl system to rotate a gear or pulley a pre-set distance that lifts the load. The ratchet and lever mechanism is equipped with a hook or fastener which is used to suspend the lever hoist from a suitable support.
Both lever hoist types may be used in any orientation for lifting, tensioning, or pulling operations although chain type hoists are generally more suited to vertical lifting.
It is suitable for production of factory, miners, agriculture, electric power, building, goods lifting, vehicle loading and unloading, etc., especially for open and no power area, more important function. Except can be separately used, can be together with hand monorail car to be hand lifting transportation vehicles, can realize the function of lift heavy things through walking around.
The lever hoist is driven, not use hand chain, but with a handle, the palm gourd has neutral position. When you turn the braking of the lever hoist to braking to neutral gear, and use hand to pull, the lifting chain will be very easy to pull down, or to pull back to convenient adjustment the lever hoist and traction distance, convenient to rapid traction or lifting.
Compared with the same lifting volume chain block, lever hoist is much smaller than chain block, whereas, it is more efficient and widely applied.
