Safety - Section 20 9/11 OM2041 Page 20-8 Driving Near High Voltage Cables When Loading Driving near high-voltage cables can cause electric shock. Always maintain safe distances between the truck and the electric cable as listed below. Make sure that the surrounding area is safe. Stop the truck in the correct loading position, then load the body uniformly. Do not leave the operator's seat during the loading operation. Parking The Truck Choose a flat, level surface to park the truck. If the truck has to be parked on a slope, put blocks behind all the wheels to prevent truck movement. The following actions are effective in preventing accidents while working near high voltages:
When parking on public roads, provide fences and signs, such as flags or lights, on the truck to warn pedestrians and other vehicles. Make sure that the truck, flags or lights do not obstruct traffic. Wear shoes with rubber or leather soles. Use a signalman to give warning if the truck approaches an electric cable. If the work equipment touches an electric cable, the operator should not leave the cab. Before leaving the truck, lower the dump body fully, move the directional control lever to PARK, stop the engine and lock everything. Always take the key with you. When performing operations near high voltage cables, do not allow anyone to approach the truck.
Check with the electrical maintenance department about the voltage of the cables before starting operations. Do not activate the wheel brake lock when parking the truck. Bleed down of hydraulic pressure may occur, causing the truck to roll away. Always shift to PARK to apply the parking brake. Working On Loose Ground Avoid operating the truck near cliffs, overhangs and deep ditches. If these areas collapse, the truck could fall or tip over and result in serious injury or death. Remember that ground surfaces in these areas may be weakened after heavy rain or blasting. Towing Improper towing methods may lead to serious personal injury and/or damage.
Freshly laid soil and the soil near ditches is loose. It can collapse under the weight or vibration of the truck. Avoid these areas whenever possible. Tow with a solid tow bar. DO NOT tow with a cable. Use a towing device with ample strength for the weight of this truck. Never tow a truck on a slope. When Dumping Inspect towing components, such as tow bars and couplings, for any signs of damage. Never use damaged or worn components to tow a disabled vehicle. Before starting the dumping operation, make sure that there are no persons or objects behind the truck. Keep a safe distance from the trucks and towing apparatus while towing a vehicle. Stop the truck in the desired location.
Check again for persons or objects behind the truck. Give the determined signal, then slowly operate the dump body. If necessary, use blocks for the wheels or position a flagman. When connecting a truck that is to be towed, do not allow anyone to go between the tow vehicle and the disabled vehicle. When dumping on slopes, truck stability is poor and there is danger of tipping over. Always use extreme care when performing such operations. Set the coupling of the truck being towed in a straight line with the towing portion of the tow truck, and secure it in position. For towing methods, refer to Operating Instructions - Section 30, Towing. Never travel with the dump body raised.
