Setting up – ‘RAMP’ signs
Many portable signals are radio controlled, but some are connected by cable. If the signals are on
the near side of the road, cables may have to cross the shuttle lane. Cables crossing a road, should
not be placed where vehicles are turning, or accelerating/ decelerating.
Where vehicles have to pass over the cable, use a cable crossing protector.
These are designed to prevent damage to the cable and to allow vehicles,
particularly those with two wheels, to cross safely.
‘RAMP’ and ‘RAMP AHEAD’ signs must be used, and it may be necessary to
weight the cable crossing protector at each end to prevent lifting or twisting.
It should not be necessary for cables to cross the footway.
