The Differences Between Lever Hoists and Chain Hoists

When it comes to lifting heavy loads, understanding the difference between a lever hoist (or lever block) and a chain hoist (or chain block) is crucial for choosing the right tool for the job.

Lever Hoist (Lever Block)

• Operated by cranking a lever/handle, suitable for various positions including horizontal, vertical, and angled pulling.
• Commonly used for pulling, dragging, stretching, and positioning heavy loads.
• Capacity is generally lower than chain hoists, moving loads up to 10,000 kg.
• Ideal for machinery alignment, maintenance, and repair in confined spaces.

Chain Hoist (Chain Block)

• Mechanical device with hand and lifting chains.
• Typically used vertically to raise or lower heavy materials by pulling the hand chain.
• Capable of lifting very large loads up to 50,000 kg.
• Ideal for high vertical loads and applications where speed is not a requirement.

How Does a Lever Hoist Work?

A lever block features a lever (handle) attached to a block with an internal gear system that powers the chain movement. To lift the load, the user needs to move the lever up and down to power the gear system. Each lever hoist is equipped with a heavy-duty safety cap attached to the load, along with a swivel at the top, allowing for lifting at various angles. Additionally, a handwheel lets the user release or retract the chain to the desired length before lifting.

When using a lever hoist, it is crucial to follow work safety rules. The lever block has a specific working load limit based on the type. Users must not exceed this limit, as it can cause the chain to snap, posing risks to both the user and others nearby. The working load limit is typically stated on the side of the hoist.

Safety Guidelines for Using a Lever Hoist

Proper use and storage of a lever hoist are essential to ensure safe operations, particularly in industrial environments. There are some safety guidelines that need to be followed when using and storing the tool, which include:

Dos:

• Always inspect the lever hoist and its accessories before use.
• Ensure the hook and support are properly aligned to avoid unnecessary side force.
• Check the condition of the brake and ensure the bottom hook reaches its lowest point without obstruction.
• Follow safe slinging techniques and follow manufacturer’s guidelines.
• Use only manufacturer-approved chains.

Don’ts:

• Avoid exposing the lever hoist to extreme temperatures, chemicals, or moisture.
• Do not use inappropriate replacement chains or apply excessive force to operate the hoist.
• Never drop, drag, or subject the hoist to unnecessary rough handling.

Storage and Handling:

• Damaged hoists should be discarded/inspeccted/repaired immediately.
• Store lever hoists hanging from the suspension hook, ensuring the chains don’t touch the ground.
• Ensure the hoist is clean, dry, and protected from corrosion.
• Always inspect the lifting setup to prevent accidents and ensure smooth operation.

By following these safety measures, you can protect both the lever hoist and its operator, ensuring reliable and safe lifting every time.
