steel wire rope winch
A chain hoist utilizes a gear mechanism and an alloy steel chain, Grade 8. The chain has a minimum tensile strength of 800 N/mm². Standard lifting capacity ranges from 250 kg to 10 tonnes. The gear reduction ratio is typically designed between 1:15 and 1:30. This ratio multiplies the manual input force 15 to 30 times. The housing is made from cast or forged steel with a yield strength of 350 MPa. The hook is manufactured from alloy steel with precise load rating. Each hook undergoes magnetic particle non-destructive testing. This process detects any surface-level flaws.
An automatic load brake with an integrated pressure disc design is used. This brake engages automatically when input force stops. Ideal load positioning accuracy is within ±3 mm. Unit weight for a 1-tonne model is approximately 15 to 20 kg. Periodic lubrication with Lithium-based grease EP-2 is essential. Safety standards like ISO 9001 and DIN 15020 govern its production. An epoxy coating enhances scratch and corrosion resistance. This device is ideal for precise and controlled lifting operations.
