Manual chain hoists are typically constructed from structural carbon steel ST37 or ST52 with tensile strength of 370 to 520 MPa. Their standard lifting capacity ranges from 0.5 to 20 tonnes. The main boom is often telescopic with a maximum length of 6 meters. The lifting system consists of a gear and an alloy steel chain, Grade 8, with a minimum breaking strength of 800 MPa. The gear ratio in the manual mechanism is designed between 1:15 and 1:30 for mechanical advantage. The base is equipped with cast iron wheels, 150 to 300 mm in diameter. These wheels can withstand a static load up to 4 times the rated capacity.
The hoist structure features a welded H-shaped or triangular frame base. The boom angle is typically adjustable up to 75 degrees. Safety is ensured by mechanical locks at joints and an automatic load brake on the drum. The steel wire rope is of type 6x19 with a steel core and a minimum safety factor of 5:1. The units self-weight ranges from 50 to 400 kg depending on capacity. An epoxy or galvanized coating increases corrosion resistance to over 500 hours in salt spray test. Ideal load positioning accuracy is within ±2 cm.You can order and buy HAND CHAIN BLOCK from Iran by contacting us through whatsaap and email.

Key Differences Between Manual and Electric Hoists
Manual hoists operate using human power lever or chain. They are characterized by low speed, limited capacity typically up to 20 tons, and the need for manpower. They have a lower purchase and maintenance cost and do not require electricity. They are suitable for temporary applications, environments without power access, or low-frequency operations. Electric hoists are powered by an electric motor. Their advantages include high speed and efficiency, wide capacity range up to several hundred tons, and precise control. They enable automation and integration with production lines. They have a higher initial capital cost and energy consumption. They require industrial electrical infrastructure and specialized periodic maintenance. The choice between the two depends on budget, frequency of use, required capacity, and existing infrastructure.
