China Suppliers Factory Manual Chain Hoist - Electric Hoist for 1 Ton, 3 Tons, 5 Tons Loading Capacities
Working Principle
The working principle of a triangular chain hoist is similar to that of a circular chain hoist, mainly by manually operating the chain to lift heavy objects. Specifically, a chain hoist is mainly composed of manual chains, hand chain wheels, ratchet wheels, gear sets, and other components. When the operator pulls the manual chain, the hand chain wheel rotates accordingly, and through the transmission effect of the gear set, the lifting chain wheel is driven to rotate, thereby driving the lifting chain to lift heavy objects.
The advantage of triangular chain hoists over circular chain hoists is that their structure is more stable and durable. The triangular design makes the shell and internal parts more compact, reduces gaps, lowers the chance of dust entering, and is less likely to deform under external impact, thus better protecting the internal parts.
In addition, the triangular chain hoist is more labor-saving, operates more smoothly, and has a longer service life during use.
Scope of Use
The triangular chain hoist has a wide range of applications, mainly used in the following fields:
■
Factories, mines, docks, warehouses, construction sites, and agricultural production: In these places, triangular chain hoists are commonly used for lifting goods and hoisting equipment, especially in situations where there is no power supply or the site is small, demonstrating superiority.
■
Flammable and explosive places: In petroleum, chemical, refining, gas extraction, oil transportation, and mining operations, triangular chain hoists are widely used due to their explosion-proof design.
■
Outdoor workplaces: Without power supply, such as buildings, bridges, paving and road construction projects, triangular chain hoists are frequently used due to their manual operation characteristics.
Key Advantages of a Triangular Chain Hoist:
✔
More stable structure: The compact design reduces internal gaps, minimizing external damage to the interior.
✔
Longer service life: Internal parts are well-protected and not easily damaged.
✔
Effortless operation: Smoother movement, less pulling force, and reduced risk of chain jamming.

Frequently Asked Questions
Q
How does a triangular chain hoist work?
It operates by manually pulling the hand chain to rotate the hand chain wheel. Through a transmission gear set, the lifting chain wheel is driven to rotate, which subsequently moves the lifting chain to raise or lower heavy objects.
Q
What are the design advantages of a triangular chain hoist over a circular one?
The triangular design offers a more compact and stable structure. It minimizes internal gaps to reduce dust accumulation, is highly resistant to external impact deformation, operates more smoothly, and requires less pulling force.
Q
Can the triangular chain hoist be used in hazardous environments?
Yes, because of its manual operation and specialized design, it is widely utilized in flammable and explosive sites such as oil transportation, refining, gas extraction, chemical plants, and mines.
Q
Is it suitable for outdoor use without power supply?
Absolutely. Since it is completely manually operated, it is ideal for outdoor workplaces lacking power sources, including bridges, buildings, road construction, and paving projects.
Q
What capacity models are available under the national standard?
We offer standard models ranging from 1 Ton, 2 Tons, 3 Tons, 5 Tons, 10 Tons, up to 20 Tons capacity, with standard lift heights of 3m, 6m, and 9m.
