WreckMaster - Towing and Recovery Training

A loaded tractor trailer with a gross vehicle weight of 74,952 lbs has become stuck in a rest area after parking on the off-ramp shoulder. The left side of the unit is on the concrete shoulder.

Upon your arrival, you park your wrecker out of the way. Once, you locate the driver, you introduce yourself advising them you will perform a walk around then come back to talk about the recovery process. You ask them if they have a scale ticket for the unit with the current load in it. The driver hands you the scale ticket advising you that the load is a sealed load which will prevent the trailer doors from being opened. The load is a mixed load of general freight.

The front axle weighs 10,972 lbs with the right side on gravel. When the driver parked, they had to make sure the whole unit was on the other side of the white painted line. Both of the drive axles on the trailer weigh 15,870 lbs. While performing your walk around you noticed the right side of the drive axles there is mud to the center of the tire. The trailer axles weigh 16,120 lbs which you noted had mud covering to just below the center of the hub.

When you complete your survey, you ask the driver if the unit still runs? does the tractor still have air pressure? will the tractor and trailer brakes release?

The driver informs you that the unit does run which allows it to build up air pressure which will allow the brakes to be released on the semi and trailer.
