Grade 80 Hoist Chain for Hand Chain Hoist and Lever Hoist EN 818-7

Description

Hoist Chain:

Function: A hoist chain is an essential part of a hoisting system, designed specifically for use with hoisting equipment such as chain hoists, electric hoists, or other lifting devices.
Construction: Hoist chains are required to flawlessly fit into the hoist sprocket drive wheel pockets and are engineered to meet much tighter dimensional tolerances than Sling Chains. They are also surface hardened to withstand continuous link-to-link abrasion demands when transferring lifting forces by running over sprocket wheels. They are often made of alloy steel and need to be made by precision manufacturing procedures to ensure reliability during lifting operations.
Features: Hoist chains may have load hooks, attachments, or other components that make them compatible with the specific design of the hoisting equipment. They are optimized for controlled lifting and lowering of loads, but should not be used like a lifting chain, e.g. choking the hoist hook back to the hoist chain.
Applications: Commonly used in manufacturing, construction, and various industries where precise lifting and positioning of heavy loads are necessary.

Grade 80 lifting chain is manufactured from high tensile alloy steel, and is heat treated for tensile strength and resistance to wear whilst also allowing for shock absorption.
Work Load Limit (WLL) is the maximum load which the chains are designed to sustain in lifting use. The mean stress at this load is 200n/mm2 (MPA) and is based on a 4:1 safety factor.
Manufacturing Proof Force (MPF) is the force to which during manufacture the chain is subjected to. The mean stress at this load is 500n/mm2 (MPA) which is 2.5 times the working load limit.
Minimum Breaking Load (MBL) is the minimum force of which the chain must withstand before failure. The mean stress at this load is 800n/mm2 (MPA). The minimum elongation before failure is 20%.
Suitable for overhead lifting applications.
