Abstract
A refuse collection vehicle having a vehicle chassis including a vehicle cab and frame with a vehicle body mounted on top of the frame. The vehicle body has a front receiving hopper separated from a rear storage compartment by means of a partition having an aperture for passage of refuse. A pendular packing device having a refuse engaging face is pivotally mounted within the receiving hopper and arcuately swings to rapidly transfer refuse through the aperture. In order to empty the storage compartment, a rear door is opened to permit egress of refuse and the partition moves longitudinally along the vehicle body to displace refuse out of the storage compartment.
Claims18
A refuse collection vehicle body having a rear and a front, comprising:
- a refuse storage compartment at the rear of the vehicle body having no front wall, but having a rear wall, two side walls, a floor and an interior cross-section, and having a rear door in the rear wall operable to open to permit egress of refuse;
- a refuse receiving hopper at the front of the vehicle body having a front wall, rear wall, two side walls and a floor separate from the rear wall, side walls and floor of the storage compartment, the rear wall of the receiving hopper profiled to match the interior cross-section of the storage compartment and having an aperture for passage of refuse to the storage compartment, the entire receiving hopper operable to longitudinally move within the storage compartment toward the rear door of the storage compartment to thereby displace refuse in the storage compartment out through the rear door;
- a pendular packing means pivotally mounted to the receiving hopper having a refuse engaging face, the packing means operable to arcuately swing within the receiving hopper, thereby transferring refuse to the storage compartment through the aperture;
- and,
- a hydraulic cylinder located below the floor of the receiving hopper for longitudinally moving the entire receiving hopper within the storage compartment.
A refuse collection vehicle comprising:
- (a) a vehicle frame having front and rear sets of road engaging wheels mounted thereunder and motive means for rotating at least one of the sets of wheels;
- (b) a vehicle cab mounted on the vehicle frame;
- and,
- (c) a vehicle body having a rear and a front longitudinally mounted on the vehicle frame rearward of the vehicle cab, the vehicle body comprising
- a refuse storage compartment at the rear of the vehicle body having no front wall, but having a rear wall, two side walls, a floor and an interior cross-section, and having a rear door in the rear wall operable to open to permit egress of refuse,
- a refuse receiving hopper at the front of the vehicle body having a front wall, rear wall, two side walls and a floor separate from the rear wall, side walls and floor of the storage compartment, the rear wall of the receiving hopper profiled to match the interior cross-section of the storage compartment and having an aperture for passage of refuse to the storage compartment, the entire receiving hopper operable to longitudinally move within the storage compartment toward the rear door of the storage compartment to thereby displace refuse in the storage compartment out through the rear door,
- a pendular packing means pivotally mounted to the receiving hopper having a refuse engaging face, the packing means operable to arcuately swing within the receiving hopper, thereby transferring refuse to the storage compartment through the aperture, and
- a hydraulic cylinder located below the floor of the receiving hopper for longitudinally moving the entire receiving hopper within the storage compartment.
