ALLOY SLINGS AND CHAIN

The only grade of chain recommended for overhead lifting is chain that has been fabricated from alloy steel. This chain may be purchased in lengths, or as a complete sling assembly to meet your requirements.

We supply chain manufactured from AISI Alloy grade steel. This is the standard of most Canadian manufacturers of alloy chain. The links of alloy chain are easily identified by an embossed symbol (A8, C8, HA8 or T) referring to grade 800 or (T) which is the international symbol for alloy chain. If neither of these symbols appear on your chain it is not recommended for overhead lifting. (Symbols should appear at least once per every foot).

Every length of alloy chain leaving the manufacturers plant is proof-tested to twice its safe working load. Every manufactured sling leaving our warehouse is also tested to double their safe working load and a numbered test certificate corresponding to the sling number is supplied.

KEEPING SLING RECORDS
Ask our representative to explain our sling and inspection program designed to improve your safety standards and lower your chain replacement costs.
