Technical Data and Specifications

The test chain assembly is available in two components: the test chain and the reel.

Test Chain Design and Features

Chains are configured as single width or double width roll sets in pitches of 4” (10 
cm) or 6” (15 cm) between adjacent rolls.

Chain rollers are provided with oil impregnated bronze bushings.

Side plates, pins, and end shackles are made from C1018 and C1020 cold rolled steel.

End Shackles are fitted with Eye links for attachment of wire rope.

Rollers are made from C1010 hot rolled steel.

Roll bars/Cotter pins are made from 304 stainless steel.

Connection links are retained by stainless steel roll bars.

A brass plate bearing the calibrated weight in lb/ft or kg/m is fixed to the end 
shackle.

The chain is sprayed with a rust inhibitor.

Nickel plated chains are available on special request.
