  • Patent number: 5868543
    Abstract: A multi-compartment collection vehicle having a packing apparatus and a multi-compartment storage body wherein the packing apparatus includes a charging hopper divided into upper and lower portions each having corresponding dual linear packers. The upper charging hopper and upper compartment of the multi-compartment storage body are connected by a ramped floor. The dividing floor of the multi-compartment storage body is ramped from a relatively lower level aligned with the upper charging portion to a higher level defining the major longitudinal portion of the dividing floor. The ramped floor arrangement increases the holding capacity of the upper portion of the charging hopper, without significantly decreasing the holding capacity of the lower storage compartment.

  • Patent number: 5833429
    Abstract: Vehicle mounted container handling devices including a rotating swivel mount and an articulated arm connected to the swivel mount are disclosed. The swivel mount includes a housing operable to rotate about a shaft in a first plane. The articulated arm is attached at one end to the housing and disposed to pivot in a second plane which intersects the first plane. A grasping device is pivotally connected to the free end of the articulated arm for pivoting in the second plane. In operation, with the grasping device opened, the articulated arm is extended to reach out toward a container of interest. The swivel mount is operated to pivot the articulated arm as required for the grasping device to engage the container. The articulated arm is operated further to lift and dump the container in the vehicle above the swivel mount addressing a variety of dumping locations.

  • Patent number: 5785487
    Abstract: A compound packing and ejecting device for a front or slide loading refuse vehicle for packing refuse from a charging hopper into an associated storage body and later ejecting the refuse from a rearward portion of the storage body without tilting the storage body. A loading device may be used to load refuse or recyclables from the front or side of the vehicle into the charging hopper. A plurality of compound packing and ejecting devices may be mounted within the charging hopper. The packing and ejecting device includes packing cylinders and ejecting cylinders coupled to a packer panel, wherein the expansion of the packing cylinders, with the ejecting cylinders retracted, linearly displaces the packer panel through a first longitudinal portion of the storage body and expansion of the ejecting cylinders, together with expansion of the packing cylinders, displaces the packer panel through the remainder of the storage body.

  • Patent number: 5056641
    Abstract: An improved discharge chute assembly for use with a concrete mixing truck includes improved chute components which are fabricated from a high strength, lightweight polymeric material. The polymeric material tends to remain smooth during wear, and permits chutes according to the invention to be manufactured much lighter than those heretofore known. According to a second aspect of the invention, an improved connecting joint structure is provided which is simple to connect and disconnect, and will not become jammed with wet concrete. Both the chute components and joint structure are constructed with smooth outer surfaces to avoid catching on clothing or other fabric. The combination of lightweight chute components and the improved joint structure yields a discharge chute assembly which is safer and more efficient to deploy at a construction site.

  • Patent number: 4762421
    Abstract: An auxiliary tag axle assembly for a work vehicle such as a ready-mix concrete truck which is positionable via actuation of a linear actuator to extend the wheel assembly from the rear end of the vehicle's frame to a ground engaging disposition and retractable to a stowed position where the wheels straddle the rear end of the frame and with the auxiliary axle elevated to a position above the level of the bottom of the frame. The need for plural actuators is obviated by utilizing a flexible cable of a predetermined length to effect desired movement of the working parts upon extension and retraction of the main linear actuator.
