LSW & SRW Series

This series has been developed for use where there is a greater requirement for safety. These units have dual micro switches syncronized to operate at the same time providing greater security since either switch will perform the cut out sequence.   

The switches can be wired in series providing extra security should a switch fail in service.

Alternatively the unit could be connected to a safety PLC where each switch can be constantly monitored.

These units carry CE marking and satisfy the requirements of BS EN12077-2 & BS EN13849-2

The standard range cover rope loads up to 100kN (10.2 tonnes) and rope diameters up to 24mm.
