OPERATING SLOW MOVING VEHICLES
ON TROLLEY ASSIST RAMPS
Personnel operating any vehicle on a trolley assist
ramp that is moving slower than trolley assisted
trucks should be aware of the following general
safety considerations:
1. Trucks traveling on trolley assist will travel
approximately 15 mph. Whenever a trolley
assisted truck is capable of overtaking slower
moving vehicles, the slower moving vehicle (if
possible) should take the required action to
allow the faster moving truck to travel up the
trolley ramps without interruption.
2. It may not always be possible to take the action
required to allow a trolley assisted haulage
trucks to overtake a slower moving vehicle. Per-
sonnel will not jeopardize the safety of them-
selves or others if conditions to not permit
overtaking.
3. Permitting a trolley assisted truck to overtake a
slower moving vehicle helps the trolley system
become more efficient and cost effective. It is
not absolutely necessary for a trolley assisted
truck to be able to overtake all slower moving
vehicles. The trolley assisted truck can travel
slower up the ramp under diesel generated
power, if necessary, to maintain safe traffic pat-
terns or traffic flows.

TRUCK FAILURE WHILE ON TROLLEY

If the truck fails while on trolley, perform the following:
1. Stop the truck using the service brakes and
apply the parking brake.
2. Move the master control lever to the DIESEL
mode.
3. Lower the pantograph.
4. Contact a supervisor.
In the event that the pantograph remains attached:
1. Remain in the cab and warn personnel not to
approach or touch the truck.
If the pantograph is attached to the trolley line,
DO NOT touch the truck while standing on the
ground.
2. Contact a supervisor on the radio. Inform the
supervisor of the situation. DO NOT allow any-
one to approach the truck until the trolley line
has been de-energized and grounded.
