Hand Chain block Introduction

Hand chain block is one of the most economical material handling equipment. It has the advantages of manual operation, simple structure, high cost performance and wide application. In addition, there are stainless steel, bronze hooks, chain and other anti-flaming features. Wheels, etc., can be used for bracelet blocks. 

The lifting capacity of hand chain block is 0.5 to 100 ton, The main parameters are as follow:

Applications of Hand chain block

■   Manual chain hoist/ Hand chain block is usually used to install machine or to handle good in short distance in the applications, such as, factory, mine, building site, dock, shipyard, warehouse, etc.  

■   Hand chain block shows its advantage when handling materials in open air or when the power supply is in short.

■   Hand chain block also can be applied to lift and transport cars, matched with monorail car, manual single girder overhead crane and suspension crane.

Advantages of Hand Chain Block

■   High safety performance.

Working Principle of Hand Chain Block

To lift good upside, pull the chain clockwise and then sprocket runs, pressing ratchet wheel and brake base as a body to rotate together, long axis rotating teeth gear, short axis and spline hole gear. Thus the lifting sprocket on the spline hole gear will drive the lifting chain to lifting goods stably.

Lifting goods down, anticlockwise pulling the chain, the brake base will separate from the brake pad, ratchet wheel will stop under the influence of ratchet pawl, five long shaft lifting sprocket driven gear in the opposite direction, then lifting goods stably. 

The chain block adopts ratchet friction chip one-way brake, can brake under load condition, ratchet pawl mesh with the ratchet wheel under the influence of spring, make the brake work safely.
