BS EN 818-7:2002+A1:2008 Short link chain for lifting purposes. Safety. Fine tolerance hoist chain, Grade T (Types T, DAT and DT)

BS EN 818-7 specifies the requirements related to safety for hoist chain, Grade T (type T quenched and tempered and types DAT and DT case hardened), for use in serial chain hoists manual and power driven.

Type DAT and type DT hoist chains possess surface hardnesses greater than core hardness and are used for power driven chain hoists to offer greater resistance to wear.

Type DT hoist chain differs from DAT hoist chain in having higher surface hardness and/or greater case depth to optimise wear resistance.

BS EN 818-7 applies to electrically welded round steel short link hoist chains conforming to BS EN 818-1.
The range of nominal size of hoist chains covered by BS EN 818-7 is from 4 mm to 22 mm.

The chains covered in BS EN 818-7 are intended for use in serial hoists. The multiple pitch is fine toleranced.

BS EN 818-7 has been prepared to be a harmonized standard to provide one means of conforming with the essential safety requirements of the Machinery Directive and associated EFTA regulations.
