Throughout this article we are going to be discussing ratchet lever hoists. We are going to look at necessary safety usage tips, together with their core advantages and how they actually operate.

There are a few additional names a ratchet lever hoist could be referred to as; they are a lever hoist or perhaps a puller hoist. They are a frequently utilised piece of equipment for lifting and tensioning tasks.

So where is a ratchet lever hoist normally used? Frequently utility businesses will use them for tensioning power cables or setting pipes down trenches or manholes. Forestry workers may use them for pulling out tree stumps, and large industrial companies may use them for the placement of heavy plant machinery, they may also be used for lifting and holding object in a specific position so they may be repaired etc.

Let us now look more closely at the basic workings of a lever hoist. Ratchet and pawl systems are normally used within a lever hoist, the ratchet is the wheel or gear that the chain rolls over and the pawl is either a hinged or pivoted catch (usually spring controlled) which engages about the teeth of the gear/ratchet to prevent it slipping in the other direction to which it is being pulled. The lever or control handle is pushed and pulled up then down which turns the chain over the gear wheel to lift the load little by little; the more you crank the handle the more it will raise up. By the flip of a switch the process is reversed and thus will lower the load.

A ratchet lever hoist will usually have a chain release device enabling the chain to be pulled out freely to the length needed to fasten to a load. They'll also have a top hook to fix the hoist to some secure fixing point, and you will have a hook with safety catch at the end of the chain to connect on to the load itself.

Using a ratchet lever hoist could have many benefits, their lightweight design means they are easy to move about, and the small versions will easily fit into a large tool box. Lever hoists are easy to use and maintain and re-chain if needed. Ratchet lever hoists are an extremely versatile device as they can be utilized in virtually any position, with pretty much any length of chain, they are also beneficial where there is no electricity. Normally found with lifting capacities up to 10,000 kgs they are ideal for many operations.

Here is a step-by-step guide to using a ratchet lever hoist;

1, attach the hoist to a suitable and secure anchor point via its top hook.
2; Advance out the chain to the length needed to attach to the load by using the free chaining facility
3; Using the bottom chain hook, you may attach the load, ensuring the centre of gravity is retained as closely as possible to ensure an evenly balanced load.
4; Push the lever setting to the up or raise setting
5; The handle / lever should now be pushed fully up then down in a continuous motion until the load is at the height required.
6, to lower the load, place the lever/switch to the down/lower position, then crank as before and your load will be slowly lowered.
7, when safely and entirely lowered you are able to remove the chain, and the job is complete.

As with all types of lifting gear you will find manufacturers user manuals to follow and standard safety codes of practice to adhere to at all times, listed below are the most important (but not all ) aspects to follow;

ALWAYS:
Check the brake before each use, and inspect the entire unit for defects frequently.
Make sure the bottom chain hook will reach the lowest position required without totally running out.
Keep the brake free from any oil or grease, but the chain ought to be well lubricated.
You must On no account;
Extend the lever/handle
Replace the chain for a longer one before consulting the provider
Use if any chain links are damaged or distorted in any way, Use if the safe working load markings are unreadable.
One of the most significant things to always remember is that your ratchet lever hoist is inspected by a specialist at regular intervals, usually 6 monthly.

We can conclude from the above that a ratchet lever hoist, if used correctly, will provide a safe, portable and versatile lifting tool, a perfect addition to any workers kit.
