Chain Block vs Lever Block: Difference and Applicable Scenarios

In the field of lifting equipment, Chain Block and Lever Block are two common types of manual hoists. Although they are both used for heavy lifting, there are significant differences in how they work, how they operate and the scenarios in which they are used. This article will provide an in-depth comparison of the core differences between the two to help you choose the most appropriate tool for your needs and provide an efficient solution for your project.

Core Differences between Chain Block and Lever Block

1. Comparison of working principle

Chain Block (Chain Manual Hoist)

Vertical lifting of heavy loads is achieved by pulling a vertical chain to drive an internal gear system. Its chain structure allows 360° rotating operation, which is suitable for scenarios that require precise positioning.

Advantages: Large lifting height (usually 3-12 m), high load capacity (0.5-20 tons), stable operation.

Lever Block (lever type manual hoist)

The lever is pulled horizontally back and forth, driving the internal ratchet mechanism to realize short-distance movement of heavy loads (usually no more than 1.5 m).

Advantages: compact size, suitable for narrow spaces, flexible and fast operation.

2. Comparison of operation mode

Chain Block: Both hands are needed to pull the chain, and the operator needs to work underneath or on the side of the equipment.

Ratchet Chain Lever Block: Lever can be operated with one hand, supports horizontal, vertical and inclined angle operation, more flexible.

3. Comparison of application scenarios

Hand chain hoists are more suitable for lifting operations. Hand chain hoists can realize different functions such as traction, wire tightening, lifting and so on.

Typical applications: heavy equipment installation in factories, high level lifting in warehouses; equipment maintenance, vehicle traction, narrow space operation.

Mobility requirements: vertical lifting and lowering at fixed points, short-distance horizontal/vertical adjustments.

How to choose the right manual hoist? Analysis of key factors

1. Choose according to the load demand

Heavy duty (≥3 tons): Priority is given to Chain Block, whose gear structure is more resistant to high pressure and suitable for long time high load operation.

Light duty (≤3 tons): Lever Block is more economical and efficient, especially suitable for frequent short-distance adjustments.

2. Selection according to space constraints

Confined space: The compact design of the Lever Block (e.g. 360° swivel handle) avoids operating dead spots.

Working in open spaces: The long chain of the Chain Block has obvious advantages, e.g. in the lifting of high shelves in warehouses.

3. Safety and maintenance costs

Chain Block: Equipped with double braking system (load brake + emergency brake), it is safer, but the maintenance cost is higher.

Lever Block: Simple structure, easy maintenance, but need to regularly check the wear of the lever pawl.

Characteristics of use

1. Differentiated advantages of Chain Block

High-precision control: Suitable for precision equipment installations that require millimeter-level positioning.

Long life design: alloy steel chain + galvanized anti-corrosion treatment, life expectancy increased by 30%.

Recommended products: [XX Brand Chain Block] supports customized chain length to meet diversified scenario needs.

2. Competitive highlights of Lever Block

Portable and flexible: the weight is only 50% of the same tonnage Chain Block, which can be carried by one hand.

Multi-functional adaptation: standard with universal hooks, support lateral traction, equipment calibration and other composite operations.

Recommended: [XX brand Lever Block] provides 3 years long warranty, no worries after sale.

User Frequently Asked Questions (FAQ)

Q1: Can Chain Block replace Lever Block?

No. Chain Block is suitable for vertical long-distance lifting, while Mini Lever Hoist is better at short-distance precision adjustment, and the two functions complement each other.

Q2: Is it better to have a bigger load for manual hoists?

No. The choice should be based on actual needs. Over-specification of load will accelerate the wear and tear of the equipment, and even lead to potential safety hazards.

Q3: How to extend the service life of manual hoists?

Lubricate the chain/lever joints regularly.

Avoid overloading and lateral pulling force.

Store in a dry environment to prevent rust and corrosion.
