5 ton chinese vital chain block , Iran
This hoist is designed for vertical lifting of loads up to 5 tons by hand. The load chain has a minimum safety factor of 4 to 1. The chain is made from Grade 8 alloy steel with a tensile strength of 800 N/mm². Gears are made from hardened steel with precision machined teeth. The design provides a standard gear reduction ratio of 30 to 1. This ratio reduces required user force to approximately 34 kgf. The body is constructed from quality cast steel with minimum tensile strength of 400 MPa. The hook is forged steel, proof-tested to 12.5 tons per standard.
The automatic brake system is mechanical and load-sensitive. It prevents uncontrolled descent even if the lever is released. Galvanized roller bearings are used for smooth operation in harsh environments. Unit weight typically ranges from 20 to 25 kg depending on chain length. The standard chain length is 3 meters. Options for 6 and 9 meters are also available. This hoist is suitable for use in temperatures from -20°C to +150°C. Periodic lubrication of all moving parts is essential for optimal performance.You can order and buy 5 ton chinese vital chain block from Iran by contacting us through whatsaap and email.

Key Considerations When Purchasing a Manual Chain Hoist
Purchasing a manual chain hoist requires attention to load capacity, lifting height, and build quality. The hoists rated capacity should be selected at least 25% more than the maximum intended load. The chain material must be made of heat-treated alloy steel with a Grade 80 or higher certificate. The gear mechanism system should operate smoothly without excessive play. The hoist hook must be equipped with a safety latch and load-tested. The chain length should be appropriate for the lifting height and workspace. The hoist body should be constructed from sufficiently thick steel with high-quality welds. A valid standard certificate such as CE, ISO 9001, or ASME B30.16 is mandatory. The devices weight and dimensions are important for portability and easy installation. After-sales service and spare parts availability are key decision-making factors.
