Terminal 5 switched on to safety
June 1st 2007 Man-machine safety specialist,
Schmersal has supplied bidirectional
position limit switches
to Alternative Access to be fitted
to over 30 bespoke powered
access platforms in Heathrow's
new T5 building.
In all 35 remote controlled
powered access gantries are being
installed – each measuring 15m
long.The 31 internal gantries are
used to maintain the terminal's
soffits and the external ones for
window cleaning and general
maintenance.
Each internal gantry is fitted with
two Schmersal T4VH 355 bidirectional
switches – one at either
end - to prevent them from being
operated under excess load.The
switches are also used to prevent
any conflict in the direction of the
cross-travel crab, i.e. if the gantry is
moving left to right, the switch
isolates the signal to prevent it from
moving right-to-left. More articles from Schmersal UK Ltd: |
