About the birth of a chain block

Chain block chain is "chain", block means "pulley", and is a tool for raising and lowering heavy objects using the principle of levering and pulley.

The principle of leverage was said to be mathematical evidence carried out by Archimedes in Greece around 200 BCE.You can lift many times the weight by hand by wrapping it around multiple pulleys with one rope as seen on the rod of a well, tie one end to a heavy object and pull the other end by hand.

Meanwhile, there is a need for a braking system to keep the lifting weight in place.This is difficult by the pulley method, so instead of a lead, a gear system instead of a pulley, a braking device for stopping and a hand chain to roll it down.

This is how a chain block winder is made.

Manual chain block features and principles of operation

Chain BlockChain Block

A manual chain block is a device that raises and lowers heavy objects with chains.

Features:

Can be used in places without power supply.You can lift heavy objects by pulling the hand chain with manipulation.

Chain Block Operating Principle:

The foundation is a "strengthening mechanism" using gears and pulley.Chain block is a machine that raises and lowers heavy objects using the principle of leverage and pulley.The gears placed inside are not just for spinning, but also applies leverage principles to amplify forces (amplifier mechanism) and change speed.

Quality Parts

Alloy steel one-piece pressure chain, precise integrated processing of alloy steel, allowing chain to pass through.Precision bearing rotation, bearing design instead of traditional gear friction, better rotational rate.

Detailed display of each chain blockAlong with the flow of the chain, it prevents the chain from escaping and increases your work efficiency.

Material Selection

The thick alloy cover is molded together by thick alloy steel which is more reliable to choose the material.
