Hand chain hoist and lever hoist are both part of the classification of manual hoist, but there are great differences in performance.
 1、Differences in working principles:
 By dragging the hand sprocket wheel and the hand chain, pressing the friction disc ratchet wheel and the brake pedestal into one body to rotate together, the hand chain hoist rotates. The 5-tooth long axle rotates the disc gear, the 4-tooth short axle and the spline hole gear. Then the lifting sprocket installed on the spline hole gear drives the lifting chain, wherefore lifting the weight smoothly. Ratchet friction disc type one-way brake is adopted by the product, and this can brake itself under load. To ensure the safe operation of the brake, the ratchet claw meshes with the ratchet wheel under the action of spring. It has the features of reliability, safety, portable, simple maintenance, high mechanical efficiency, small Bracelet tension, light self-weight, beautiful appearance, small size and durable. Hand Chain Hoist and Lever Hoist are used in Factories, mines, construction sites, docks, warehouses, etc. as installation machines and lifting cargo, especially for open-air and power-free operations are suitable. for flammable and explosive places Hand Chain Hoist and Lever Hoist also play important roles.
       Through the manual wrench handle, the lever hoist obtains the linear traction force matching the load by means of the lever principle, which plays an important role on a clamp body of the load in the machine core in turn, and drives the load to run. The utility model has the advantages of compact structure, light  weight, small size, convenient carrying, safety and reliability, long service life, small spanner force, and small wear and tear to the steel wire rope. Lever hoist is able to carry out lifting, traction, descent, calibration and other operations. If equipped with special devices, not only non-linear traction operation can be done, but also suitable operation position can be conveniently selected, or the load capacity of smaller tonnage machines can be multiplied. Therefore, several lever hoists can be used in parallel operation for larger tonnage loads.
 2、What's the biggest difference between the hand chain hoist and the lever host?
 When comparing with the same lifting volume hand chain bock, lever hoist is much smaller than hand chain hoist, thus it is more efficient and widely  used.
 3、Which is more economical when using hand chain hoist and lever hoist?
       Generally speaking, the design of lever hoist is mainly used when there is no good pulling posture or the space is small, which is used as horizontal pulling force, which saves labor horizontally, and hand chain hoist is used vertically. Hand chain hoist is not driven by hand zipper, but by rocker.
 4、When to use hand chain hoist and the lever hoist?
 The lever hoist is driven with a handle instead of hand chain, the lever hoist has neutral position. The lifting chain will be very easy to pull down, or to pull back to convenient adjustment the lever hoist and traction distance, if you turn the braking of the lever hoist to braking to neutral gear, and use hand to pull, convenient to rapid traction or lifting.
 5、Which is more widely used for hand chain hoist and lever hoist?
        The lever hoist has space. When you pull the brake of the lever hoist into  space, you can easily pull down the weight with your hand, or pull back to adjust the distance between the hand chain hoist and lever hoist, and this is convenient for quick traction or lifting. In addition, It is more efficient and wider for its function and the volume of the lever hoist.
 Above are generally the differences and competition between Hand Chain Hoist and Lever Hoist.
