Detailed explanation of chain length specifications of hand chain hoist

1. Calculation method of chain hoist chain length

The chain length of a chain hoist generally refers to half of the sprocket diameter. Common chain length specifications are 0.25 inches, 0.375 inches, 0.5 inches, 0.625 inches, 0.75 inches, 1 inch, etc. For example, a chain hoist with a sprocket diameter of 200 mm should have a chain length of 100 mm.

2. Classification of chain hoist chain specifications

The chain specifications of a chain hoist can be divided into the following categories:

1. G80 chain: G80 chain is a type of high-strength chain with high tensile strength, better wear resistance, and better heat resistance. It is commonly used in hoisting, chain hanging, tension testing and other fields.

2. G70 chain: G70 chain is also a type of high-strength chain, but its strength is slightly lower than that of G80 chain. It is commonly used in trailers, traction, transportation and other fields.

3. G43 chain: G43 chain is a general strength chain, commonly used in light applications such as pastures, fields, and construction.

3. Hand chain hoist chain material

Hand chain hoist chains are usually made of steel, stainless steel, galvanized, etc. Among them, steel chains have high strength but are prone to rust; stainless steel chains do not require plating and have good corrosion resistance; galvanized chains are plated with a layer of zinc on the surface, which has good corrosion resistance.

4. Matters to note when purchasing hand chain hoist chains

1. Determine the working load and chain length of the hand chain hoist, and choose the appropriate chain specifications.

2. Check whether there are obvious defects and deformations on the surface of the chain to ensure that the chain quality is reliable.

3. When purchasing hand chain hoists, products produced by regular manufacturers should be selected to avoid using inferior products.

In short, the correct selection of hand chain hoist chain length specifications is very important for the use of hand chain hoists. It is hoped that readers can better understand the knowledge related to the chain length specifications of hand chain hoists through the introduction of this article, so as to avoid problems when purchasing and using hand chain hoists.
