Grade 80 Medium Link Chain

The size of TOPONE® Medium Link Chain is designed according to DIN764. The working load and breaking load are produced according to Grade 80 chain. The use of alloy steel makes the chain performance more stable and reliable. However, due to the problem of chain size, we do not recommend using it for lifting work.

Grade 80 Medium Link Chain
Introduction

TOPONE® industrial chain is suitable for various industrial, agricultural, forestry and animal husbandry scenarios. It can be used for transmission and lashing. It has the size of ordinary industrial chains and the working load of high-strength lifting chains. It is particularly suitable for high-load transmission.

  • 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 factor of safety.
  • 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%.


Standards

!This product is not recommended for overhead lifting. It is strictly prohibited to use it in excess of the working load (WLL).

!Any surface coating will affect the mechanical properties of the chain.Please ask staff for details.

!Do not weld other accessories directly to the chain when used on deck.

We follow standards:

EN 818-1

EN 818-2

DIN 764


Optional surface treatment: natural black, powder coating, black electrophoresis, electro-galvanizing, hot-dip galvanizing, Dacromet.




Ambient temperature during use:

Min.: -40 ℃

Max.: 200 ℃

If the application scenario exceeds or is lower than the recommended operating temperature, please consult the staff to see if it is feasible.
