Truck body

Abstract

A truck body includes a front wall, side walls, and a floor. The floor has panels disposed at predetermined angles from the horizontal that, with the other parts of the body, form a payload volume within the body. The floor also includes a tail panel disposed at a lesser angle from the horizontal to facilitate the shedding of the payload when dumping, and further to maintain the center of mass of the payload in a generally forward position during dumping.

1 . A mining dump truck combination body for the transport of materials of different densities, the body having a front wall, opposed side walls, and a longitudinal floor and the body being mountable to a truck chassis at pivot points under the body, the floor comprising:
 a first transverse forward section disposed to create an angle of between 5 and 26 degrees from the horizontal when the body is in a payload transporting orientation;   a second transverse intermediate section disposed to create an angle of between 6 and 26 degrees from the horizontal when the body is in a payload transporting orientation, the first and second sections together with the side walls and the forward wall thereby forming a payload volume in which a payload being transported has a center of mass forward of the pivot points when the body is pivoted upward to dispense the payload; and   a transverse tail panel affixed to the intermediate section, the tail panel being disposed to create an angle of between 0 and 15 degrees from the horizontal when the body is in a payload transporting orientation, thereby enabling the tail panel to act as a partial support for a volume of a low density payload, the tail panel forming a spillway for a payload so that the center of mass of the load remains forward of the pivot points when the body is pivoted upward to dispense the payload.   
     
     
         2 . A truck body having a front wall, opposed side walls, and a longitudinal floor, the floor comprising:
 a first transverse forward section disposed to create a first predetermined angle from the horizontal when the body is in a payload transporting orientation;   a second transverse intermediate section disposed to create a second predetermined angle from the horizontal when the body is in a payload transporting orientation; and   a transverse tail panel affixed to the intermediate section, the tail panel being disposed to create a third predetermined angle from the horizontal when the body is in a payload transporting orientation, the tail panel forming a spillway for a payload so that the center of mass of the load remains forward of the pivot points when the body is pivoted upward to dispense the payload.   
     
     
         3 . The truck body of  claim 2  in which the first predetermined angle is between 5 and 26 degrees. 
     
     
         4 . The truck body of  claim 2  in which the second predetermined angle is between 6 and 26 degrees. 
     
     
         5 . The truck body of  claim 2  in which the third predetermined angle is between 0 and 15 degrees. 
     
     
         6 . The truck body of  claim 2  in which the tail panel may act as a partial support for a volume of a low density payload. 
     
     
         7 . The truck body of  claim 2  further comprising at least one pivot point under the body for mounting the body to a truck chassis. 
     
     
         8 . The truck body of  claim 7  in which the floor, side walls and forward wall form a payload volume in which a payload has a center of mass forward of the pivot point when the body is pivoted upward to dispense the payload. 
     
     
         9 . A dump truck body for the transport of materials of different densities, the dump truck body configured to be mounted on a truck chassis having at least one front axle having a center point and at least one back axle having a center point, the center point of the at least one front axle and the center point of the at least one back axle thereby defining a reference line, the dump truck body having a longitudinal floor with a pair of laterally opposed spaced upwardly extending side walls coupled to the floor and a forward upwardly extending front wall coupled thereto between the side walls to create a volume for carrying a payload having a center of mass, the dump truck body further comprising at least one pivot point at which the truck body may be pivotally mountable to the truck chassis, the longitudinal floor comprising:
 a first transverse forward section disposed to create an angle of between 5 and 26 degrees as compared to the reference line when the body is in a payload transporting orientation;   a second transverse intermediate section disposed to create an angle of between 6 and 26 degrees as compared to the reference line when the body is in a payload transporting orientation; and   a transverse tail panel affixed to the intermediate section, the tail panel being disposed to create an angle of between 0 and 15 degrees as compared to the reference line when the body is in a payload transporting orientation, thereby enabling the tail panel to act as a partial support for a volume of a low density payload, the tail panel forming a spillway for a payload so that the center of mass of the load remains forward of the pivot point when the body is pivoted upward to dispense the payload.   
     
     
         10 . The truck body of  claim 9  in which the tail panel forms a spillway for a payload so that the center of mass of the payload remains forward of the pivot point when the truck body is pivoted upward to dispense the payload.
