A chain block (also called a manual chain hoist) is a hand-operated lifting device used to raise and lower heavy loads by pulling on a hand chain.
Unlike electric hoists, a chain block does not require power supply, which makes it highly versatile for construction sites, workshops, warehouses, shipyards, and maintenance work.
The working principle is based on a mechanical gear system: when the operator pulls the hand chain, the internal gears multiply the pulling force, enabling a single person to lift several tons of weight safely and easily. This is why the chain block is a standard lifting tool in many industries.
2. Chain Block vs Manual Chain Hoist vs Lever Chain Hoist
Although the terms are sometimes mixed, they are not identical. Here is a simple comparison:
Device | Description | Best Use Case |
Chain Block (main keyword) | Vertical lifting using a hand chain and gearbox | Stationary lifting of heavy loads |
Manual Chain Hoist | Another name for chain block (most people search either term) | General industrial lifting |
Lever Chain Hoist | Uses a lever handle instead of hand chain, can pull horizontally | Tensioning, pulling, positioning, limited space |
Conclusion:
All chain blocks are a type of manual chain hoist, but lever chain hoists are more suitable for pulling and positioning, while chain blocks are optimized for straight vertical lifting.
A chain block is popular worldwide because it offers three key advantages:
No electricity, no hydraulic system — it works anywhere.
Even a 2 ton hoist can be operated by a single worker with minimal effort.
Lower maintenance and lower risk compared to powered hoists.
Additional reasons:
Easy to install on I-beams or trolleys
Lightweight and portable
Reduced operating cost
Long service life due to alloy steel chain
Among all load capacities, the 2 ton hoist is the most commonly purchased specification.
It provides an ideal balance between lifting power and portability. It is widely used in small factories, repair workshops, construction sites, and warehouse operations.
Why 2 Ton Chain Block Is So Popular:
✔ Sufficient capacity for most industrial loads
✔ Easy for one person to operate
✔ Compact size and simple installation
✔ Lower purchase cost compared to electric hoists
✔ Reliable and low-maintenance design
Many buyers search “2 ton hoist” when they are looking specifically for a chain block, which means this capacity also carries strong commercial keyword intent in Google search.
A chain block is suitable for a wide variety of lifting operations:
Application | Description |
Construction | Lifting steel beams, precast concrete, scaffolding |
Manufacturing | Installing machines, moving heavy components |
Shipbuilding | Positioning ship sections and marine parts |
Mining | Maintenance of heavy mining equipment |
Warehouses | Loading/unloading materials |
Maintenance Work | Equipment repair and assembly |
Chain blocks are also used in tight or remote locations where electricity or compressed air is not available — this is one of their biggest competitive advantages.

When selecting a chain block, consider the following factors:
Choose based on maximum working load (2 ton hoist, 3 ton, 5 ton, etc.).
Standard lifting height is 2.5m to 3m, but can be customized.
Alloy steel load chain (G80) is recommended for durability.
For dusty, outdoor, or wet areas, select anti-rust coated models.
Choose between fixed suspension or trolley-mounted units.
Make sure the chain block complies with EN, CE, or ASME standards.
A properly selected chain block can last for many years with minimal maintenance.

Q1: Is a chain block the same as a manual chain hoist?
Yes. A chain block is a type of manual chain hoist used for vertical lifting.
Q2: What capacity should I choose?
For general lifting work, a 2 ton hoist is the most popular choice.
Q3: Can a chain block be used horizontally?
Not recommended. For horizontal pulling, use a lever chain hoist instead.
Q4: How often should a chain block be inspected?
Before each use visually, and periodically according to EN or ASME inspection guidelines.
Below is the standard parameter table for a chain block, including the most popular 2 ton hoist model:
Capacity | Standard Lift (m) | Hand-Pull Force (N) | Load Chain Dia. (mm) | No. of Falls | Net Weight (kg) |
0.5 Ton | 2.5 – 3 m | 220 | 6 mm | 1 | 8 |
1 Ton | 2.5 – 3 m | 250 | 6 / 7.1 mm | 1 | 10 |
2 Ton (Popular) | 2.5 – 3 m | 320 | 8 mm | 2 | 12 |
3 Ton | 3 m | 340 | 10 mm | 2 | 20 |
5 Ton | 3 m | 360 | 10 mm | 3 | 28 |
10 Ton | 3 m | 380 | 10 mm | 4 | 48 |
✔ Lifting height can be custom-made (3m / 6m / 9m / 12m / 18m)
✔ Extra long chain available for warehouse / marine applications
✔ Optional stainless steel hooks for anti-corrosion environments
