Safe access
October 1st 2005

In conjunction with its partner-distributor Parmley Graham, Schmersal has supplied bi-directional position limit switches to Alternative Access for fitting to powered access platforms in Heathrow’s Terminal 5.

Each of 31 internal gantries has two Schmersal T4VH 355 bi-directional switches, one at either end, to prevent them being operated while under excess load. Switches also prevent any conflict in the direction of the cross-travel crab.
