Dump Truck Operations & Spotter Use
Spotter in the Dump Area
The purpose of a spotter in the dump area is to guide trucks, ensure stable dumping, and watch for overhead obstructions and drop-offs. Dump areas present multiple hazards including unstable edges, overhead power lines, uneven ground, and other equipment. The spotter positions themselves where the driver can see them and directs the truck to the dump point safely.
Avoid Overloading Dump Trucks
Avoid overloading dump trucks for reasons of compliance, brake and stability limits, and road laws. Overloaded trucks exceed their braking capacity, stress the frame and suspension, damage haul roads, and violate DOT weight limits. Operators loading trucks must know the truck's capacity and avoid overfilling.
Keep Dump Body Down During Travel
Keep the dump body down during travel to lower the center of gravity, prevent tipping, and avoid overhead strikes. A raised or partially raised dump body dramatically raises the machine's center of gravity and can contact overhead lines, bridges, or structures. Always verify the body is fully lowered before traveling.
Dump Body Hazard
Traveling with the dump body raised is a leading cause of tip-overs and overhead contact. Always verify the body is fully lowered before leaving the dump area.
Spotters guide trucks, ensure stable dumping, and watch for overhead hazards. Avoid overloading for compliance and stability. Keep the dump body down during travel to lower the center of gravity and prevent overhead strikes.
