Terms and definitions of hardware for fall arrest system

1. termination connector (class T)

self-closing connector designed to allow the fixing as an element of a sub-system in such a way that the loading is in a predetermined direction.

2.anchor connector (class A)

connector which closes automatically, designed to be linked directly to a specific type of anchor as a component.

3.screwlink connector (class Q)

connector which is closed by a screw-motion gate, which is a load bearing part of the connector when fully screwed up (see Figure 4), intended to be used only for long-term or permanent connections

4. gate

part of the connector which can be moved to open it

NOTE The gate can, for example, move by pivoting about a hinge (hinged gate), or by a sliding motion (sliding gate) or by a screw motion (screw-motion gate).

5. self-closing gate

gate which moves automatically to the closed position when released from any open position

There critical steps to ensure the quality

Ø spectrographic analysis

Ensure proper metallurgy content of all raw materials.

Ø Proof load Testing

All safety harness connecting components are 100% proof loaded to 3600IBS/16KN.

Ø Ultimate breaking Load Test

Connecting and adjusting components are batch tested for ultimate breaking strength.
