In control of loading bay safety
February 1st 2011 The new Hörmann Dock
Control is a safety control
system for loading bays that
links the loading door and
dock leveller controls to
proximity sensors and
warning traffic light
systems.
A dock buffer with an
integrated proximity sensor
guides a vehicle onto a
loading bay via the external traffic light
system. Once on the bay a wheel chock,
also with an integrated sensor, needs to
be correctly positioned before the
loading bay controls will operate.
When the vehicle is docked securely
the internal red traffic light flashes to
indicate that the door can be opened,
allowing the dock leveller controls to
operate. The dock leveller then controls
the traffic light system.
Should the vehicle move
or the wheel chock become
displaced an alarm sounds
and the loading lights turn
to red immediately.
Additionally, if the vehicle
pulls off the bay whilst there
is a load on the dock leveller
platform the emergency stop
valve will automatically lock
the platform in position.
The sequence reverses after loading
with the door only able to operate once
the dock leveller is correctly parked.
When the door is closed the external
amber light flashes to indicate that the
wheel chock can be removed, turning
green once it is secure. More articles from Hormann UK Ltd: |
