What is a lever hoist?
Lever hoists are portable devices used to manually lift, lower or pull a load. A lever hoist can also be used for tensioning and lashing loads for transport. Lever hoists have the advantage of being able to lift in most positions, including horizontally and vertically, where chain hoists can typically only be used vertically.
How does a lever hoist work?
Lever hoist's (also known as blocks) have a handle on the side of the block which houses an internal gearing and ratchet system fitted with load chain. A lever block works by cranking the lever up and down to engage the ratchet and pawl system, which causes the load to move a set distance per crank. The direction of the internal gear can be easily switched, to move the load up or down as needed. There is a hook on the end of the load chain for easy attachment to a load, and a hook attached to the housing of the lever block for attachment to secure support (e.g. steel beam).
The load chain on a lever hoist comes in standard lengths of 1.5 or 3 meters, with working load limits available from 250kg ' 9 tonne. Other sizes available at request.
What is a chain block?
Chain blocks are portable devices used to manually lift or lower a load. A hand-operated chain hoist is usually smaller and more compact compared to an electric hoist of the same size. Chain blocks are able to lift in a vertical position only. If they are side loaded or used horizontally it is possible for the mechanism to jam.
How does a chain block work?
A chain block is operated manually, made from a combination of internal geared pulleys fitted with chain. The user will pull down on the hand chain, this will turn a pulley mechanism inside the hoist to move the load. There is a hook on the end of the load chain for ease of attachment to the load and a hook on top to secure the chain hoist to a suitable support.
Chain blocks are available in either a manual or electric mechanism, with sizes available from 250kg ' 20t in 3 and 6metre heights of lift. Other sizes are available at request.
If you have a load to move, a chain block or chain hoist can handle it. It may seem like both have the same features visually looking at the operation, yet they differ in many ways. Let me satisfy that curiosity by sharing What Is The Difference Between A Chain Hoist And A Chain Block?
What differentiates chain hoists from chain blocks is their usage. Chain hoists use rotating motions of the lever to navigate heavy objects, while chain blocks operate by pulling the hand chain to lift cargo off the ground. A chain hoist operates manually, and a chain block works mechanically.
Chain hosts and chain blocks have similar functions, yet they differ in many ways. To understand their differences, you will first need to know how they work and the benefits and disadvantages of each. Join me on this discovery.
A chain hoist operates as a pulley system to lift heavy objects. They are attached to the horizontal beam of the crane and connected to the trolley. They move the load backward and forwards on the trolley. Instead of working automatically, they operate manually.

It can be operated in two ways manually or with electricity. The load lifts by a rope or wire reeled around a drum. The load is attached to the hook. The chain, fiber, and wire are lifting mediums. The electric chain hoists have a motor and a brake to ensure that the load holds when raised.
Manual Chain Hoist ' One of the significant disadvantages of manual chain hoists is that they have a limited lifting capacity, usually under five tons; hence, they serve no purpose to lift large loads.
Electric Chain Hoists- Although electric change hoists have some excellent benefits, the additional outlay for electric costs and the replacement costs of hydraulics can work against them.
There are two types of chain hoists;
Manual chain hoists are a more cost-effective solution. A manual chain hoist is operated manually and does not require any electricity or power supply. They are easier to maintain with no complex wires or hydraulic systems to consider. Chain Hoists are also compact and quite portable for easy transportation.
Manual chain hosts can come in two styles;
These hand chains require both hands in the operation process. As you pull one chain, a second chain is needed to navigate the lifting of the load.
Apart from having the lifting mechanism control most of the workload, there is also a braking system that enables you to prevent the load from slipping back. Despite the submersion of the cargo in the air, you can still operate the chain from the ground.
Unlike hand chain hoists, they only require one hand in the operation process. They are ideal for horizontal, low vertical, and angle loads. Their operation process is similar; required is the cranking of a side lever attached to the lifting mechanism. Due to the lever's location, you will need to be close to the hook to ensure smooth operation.
The electric chain hoist operates by a power supply and electricity, which often means their usage can increase the cost of electricity bills. The electrical hydraulic systems can often be time-consuming and tricky to maintain, considering the price of repairs to complex motors and wires. Investing in an electric chain hoist can be costly.
A chain block is a mechanical device used to lift heavy loads. By pulling the hand chain, the load moves. Chain blocks work in the agricultural, manufacturing, building, and mining industry. The cargo is attached to the hook's end; lifting occurs when the chain block winds the chain around. Chain blocks can lift heavy loads of up to 30 000 kg with minimal effort.
The components of a chain block include a lifting chain, a base hook, and a hand chain. When a load needs to be lifted or dropped, it connects to the base hook via the chain block. The pulling of the hand chain causes the gears and inside loops to tighten. The tightening causes tensions, which causes the load to lift off the ground.
Before lifting the goods, it is advisable to raise them a short distance from the ground to confirm that the load is adequately balanced and that the equipment is working at its optimum. During the lifting process, ensure that the chain pulls to avoid any jolting or tangling during the process.
Although chain hoist and chain block's primary function is lifting, one significant difference is the operation process. If you explore which would be the more suitable choice, perhaps you should consider the three most essential factors, cost, operation, and flexibility, to help guide you in making an informed decision.
