Towing; Safe Parking Procedures - Komatsu 730E Operation & Maintenance Manual

Operation - Section 3
Page 3-10
Prior to towing a truck, many factors must be carefully considered. Serious personal injury and/or significant prop-
erty damage may result if important safety practices, procedures and preparation for moving heavy equipment are
not observed.
Do not tow the truck any faster than 5 MPH (8 kph).
A disabled machine may be towed after the following MINIMUM precautions have been taken.
1. Shut down engine.
2. If truck is equipped, install hydraulic connections for steering and dumping between towing and towed vehi-
cles. Check towed vehicle for braking system.
3. Inspect tow bar for adequacy (approximately 1.5 times the gross vehicle weight of truck being towed).
4. Determine that towing vehicle has adequate capacity to both move and stop the towed truck under all condi-
tions.
5. Protect both operators in the event of tow bar failure.
6. Block disabled truck to prevent movement while attaching tow bar.
7. Release disabled truck brakes and remove blocking.
8. Sudden movement may cause tow bar failure. Smooth and gradual truck movement is preferred.
9. Minimize tow angle at all times - NEVER EXCEED 30
tow bar.
The operator must continue the use of safety precautions when preparing for parking and engine shutdown.
In the event that the equipment is being worked in consecutive shifts, any questionable truck performance the
operator may have noticed must be checked by maintenance personnel before the truck is released to another
operator.
1. The truck should be parked on level ground, if at all possible. If parking must be done on a grade, the truck
should be positioned at right angles to the grade.
2. The parking brake must be applied and/or chocks placed fore/aft of wheels so that the truck cannot roll. Each
truck should be parked at a reasonable distance from another.
3. Haul roads are not safe parking areas. In an emergency, pick the safest spot most visible to other machines in
the area. If the truck becomes disabled where traffic is heavy, mark the truck with warning flags in daylight or
flares at night.
