How Do Non-sparking Chain Hoists Work?

08th. May, 2024

What are non-sparking chain hoists?

There are lots of methods used in moving heavy loads but one of the oldest used is a hoist. Hoists come in many guises and can be used to successfully and safely move heavy items, however, they do need to be set up correctly and used properly. If set up and used correctly, a non-sparking chain hoist is one of the easiest and most efficient ways of lifting a load.

A chain hoist is operated by hand. An operator will pull down on one of the chain loops on one side of the chain. This will turn a pulley mechanism inside the chain hoist housing. When this pulley turns, it will lift up the end of the other chain which usually has a hook on the end. By pulling down on one chain, the manual hoist is actually able to increase the mechanical work that is being done. This is caused by the gear ratio inside the manual chain hoist.

How does a chain hoist work?

Inside the chain hoist housing are two gears. One is smaller than the other. Most non-sparking chain hoists use a 20cm and 25cm gear. The two gears are attached, so when one moves, the other moves. The chain is looped over the smaller gear and then hangs down in a loop (the loop you pull on). The chain then continues on over the larger gear and down to a point or another loop, depending on the type of hoist you are using. The operator pulls on the section of the chain which is looped over the smaller gear.


What are the uses of non-sparking chain hoists?

A chain hoist is considered by many to be the most basic form of lifting tool. They can be used in a multitude of different ways, not just to perform vertical lifts but also can be used to drag or position a heavy load. Manual non-sparking chain hoists can also be used below the hook of a larger crane to allow for final, precise adjustments. non-sparking chain hoists are often purchased with ancillary equipment, such as beam clamps, shackles, or slings to assist connection to the load.

Non-sparking chain hoists have three uses:

  • Lifting an object

  • Pulling an object

  • Load equalization

Applications are varied and include:

  • Ship wharfs

  • Slaughterhouses

  • Paper mills

  • Steel mills

  • Production plants

  • Maintenance works

  • Renewable energy installations

  • Vehicle & aircraft workshops

  • In fact, there are hundreds more.

Examples of items lifted or shifted by a chain hoist:

  • Engines or motors

  • Transformers

  • Dies

  • Injection mold tools

  • Turbines

  • Steel coils
