Komatsu — TRUCK FAILURE WHILE ON TROLLEY

Operation - Section 30 OM3070 Page 30-24 Operating Instructions OPERATING SLOW MOVING VEHICLES ON TROLLEY ASSIST RAMPS TRUCK FAILURE WHILE ON TROLLEY If the truck fails while on trolley, perform the following: 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. Stop the truck using the service brakes and apply the parking brake. 2. Move the master control lever to the DIESEL mode. 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. 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. 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. 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.
