Abstract
A mud flap lifting system specifically for a live bottom type trailer vehicle in which asphalt or similar is dispensed from the rear of the trailer load box for a paving operation using a paving machine in tandem with the trailer. Pneumatic lift cylinders on each side of the trailer load box are used to retract and extend cables running rearwardly from the cylinders to and through cable guides positioned vertically above the mud flaps. The cables are operable to pull or lift the lower portions of the mud flaps upwardly and outwardly into curved configurations located above a paving machine roller as it engages the rear wheels of the trailer, and at a height designed to engage the paving machine hopper as it engages the trailer.
