โ๏ธ Working Principle
Drive the rotation of the hand chain wheel by manually operating the chain. Specifically, when pulling the manual chain, the hand chain wheel rotates, which in turn drives the friction plate ratchet, brake seat, as well as the plate gear, short shaft, and spline hole gear on the long shaft to rotate together. The lifting sprocket installed on the spline hole gear rotates accordingly, pulling the lifting chain to achieve the goal of smoothly lifting heavy objects.
The structure of a circular chain hoist includes components such as a bracelet strip, bracelet wheel, ratchet wheel, toothed short shaft, spline hole gear, toothed long shaft, etc. The core lies in the design of the gear set, where the small gear rotates twice to drive the large gear to rotate once. Through the pulling of the chain, the torque is amplified twice through the long and short shafts of the gear, making it easy to lift several tons of heavy objects.
The characteristics of a circular chain hoist include simple use, easy portability, and suitability for short distance lifting of small equipment items. Its lifting capacity is generally around 10 tons, and the lifting height is usually 6 meters. Hand pulled hoists also have the advantages of labor-saving and low cost, and are widely used in factories, mines, buildings, and other fields, especially in areas without power and with narrow spaces where operations have obvious advantages.

๐ Scope of Use
Circular chain hoists are mainly used for lifting and transporting heavy objects, suitable for various scenarios including construction sites, logistics and warehousing, agricultural production, and industrial production.
Construction Site
In construction site construction, circular chain hoists are commonly used to transport various heavy objects and solve lifting and handling problems during construction.
Logistics & Warehousing
In logistics warehousing scenarios, chain hoists can help transport goods and improve work efficiency.
Agricultural Production
Hand pulled hoists are widely used in agricultural production, such as the hand pulled hoists of tractors, which can drag large agricultural machinery and equipment.
Industrial Production
In the industrial production process, chain hoists are used to transport heavy objects such as machinery and equipment and are a good helper for workers.
โ Frequently Asked Questions
What is the maximum lifting capacity of a round chain hoist?
Our round chain hoists are available in specifications ranging from 1 ton to 100 tons, with standard models commonly used at capacities around 10 tons. Custom options are available based on customer requirements.
What is the standard lifting height of the circular chain hoist?
The standard lifting height ranges from 3 meters to 12 meters. The minimum distance between the two hooks is 185 mm, and the increase speed is 3 m per operation cycle.
What material is the chain made of?
The chain is made of G80 manganese steel, which offers excellent tensile strength and impact resistance. The quenched manganese steel hooks feature thickened tongue plates to prevent accidental disengagement during operation.
Does the round chain hoist require electricity to operate?
No. The circular chain hoist is a fully manual device. It operates by hand-pulling the chain, making it ideal for use in locations without access to electricity or in confined spaces where powered equipment cannot be used.
What industries or environments is this hoist suitable for?
The round chain hoist is widely used across construction sites, logistics and warehousing facilities, agricultural production environments, industrial workshops, and truck loading/unloading operations. It is especially advantageous in narrow or power-restricted areas.
What packaging and customization options are available?
Products are packaged in wooden packaging to ensure safe transportation. The hoists are made from forged alloy steel and are available in multiple specifications from 1T to 100T. Custom configurations can be arranged according to specific customer needs.
