What is a chain block?

The Chain Block is a mechanism used to raise or lower heavy loads with relative ease. The internal gears of the Chain Block wind the chains around, lifting the object that is attached to the end or hook. This means that very little force is required to lift large, heavy loads of up to 30,000 kg.

The role of the chain block

A chain block, also known as a hand chain hoist or manual hoist, is a mechanical device that is used to lift, lower, and move heavy objects. It consists of a chain that is passed through a pulley system, and it is operated using a hand crank or lever. The chain block is attached to the object that needs to be moved using a hook or other type of fastener, and it is used to lift and move the object by pulling on the chain.

Chain blocks are commonly used in a variety of industries, including construction, manufacturing, and shipping. They are particularly useful for handling heavy loads that are difficult to move using other methods, and they are often used to lift and move objects such as engines, machinery, and building materials.

Chain blocks are designed to be strong and durable, and they are typically made of high-quality materials such as steel or alloy. They are available in a range of sizes and styles to suit different types of loads and applications. Some chain blocks are designed for use with specific types of chains, such as alloy chain or high-test chain, while others are compatible with multiple types of chain.

In order to use a chain block, the load must first be attached to the hook or other fastener. The chain is then passed through the pulley system and the hand crank or lever is used to lift or lower the load. The speed at which the load is moved can be controlled by adjusting the hand crank or lever, and the position of the load can be adjusted by moving the chain block to a different location.

It is important to use chain blocks safely in order to avoid accidents and injuries. This includes following the manufacturer's instructions and guidelines, as well as ensuring that the load is properly balanced and secured. It is also important to regularly inspect the chain block for signs of wear or damage, and to replace it as needed.

In summary, a chain block is a valuable tool for handling heavy loads. It is strong, durable, and versatile, and it is essential for a variety of industries that rely on the movement of heavy objects.

Frequently Asked Question

Do you have any question?

Put it in simple words, a Chain Block is a lifting device operated by pulling a hand chain. A Lever Block is a lifting device operated by rotation of a handle/ lever.

Also known as chain blocks or chain pulley blocks, chain hoists are used extensively to move heavy loads through chain pulling. While most chain hoists are operated by hand, lever blocks (or ratchet lever hoists) are operated by pulling a manual lever either forward or backward.

Chain block gives you the ability to lift huge loads up to 50 tonnes with ease by using mechanical advantage. Its working load limit (WLL) is greater than a lever hoist which lifts a load up to 10,000 kg.

The chain block contains two wheels or cogs in which the chain is wrapped around. Both electric chain blocks and manual chain blocks have the same fundamental functions - when the chain is pulled, it wraps around the wheels which adds torque to the lifting mechanism, pulling the item that is on the other end of the chain (usually with a strong hook) and lifting it off the ground - the wheels inside the block are how they are able to lift heavy loads - even when operated manually.

A chain block has a strong chain for lifting objects and attaching hooks to, manual lifting blocks have a hand chain which can be used for pulling by hand to bring the load up (these are powered by motors in electric chain blocks), they also have a grabbing hook for applying the lifting load. Electric chain blocks are the most common method, however, manual chain blocks are commonly used to lift lighter loads as they aren’t as expensive and are easier to move.
