Abstract: A wireless hoist system including a first hoist device having a first motor and a first wireless transceiver and a second hoist device having a second motor and a second wireless transceiver. The wireless hoist system includes a controller in wireless communication with the first wireless transceiver and the second wireless. The controller is configured to receive a user input and determine a first operation parameter and a second operation parameter based on the user input. The controller is also configured to provide, wirelessly, a first control signal indicative of the first operation parameter to the first hoist device and provide, wirelessly, a second control signal indicative of the second operation parameter to the second hoist device. The first hoist device operates based on the first control signal and the second hoist device operates based on the second control signal.

Abstract: A mixing fin assembly adapted to mix and guide materials in a rotatable mixing drum of a type used in a transit concrete mixing vehicle includes a spiral mixing fin designed to extend transversely into the drum constructed of a lightweight, moldable polymeric material which is flexible and resistant to abrasion, the mixing fin includes a plurality of conjoined sections that are fit together, preferably utilizing fin locking tabs and mating fin locking sockets. A preferred way of mounting the mixing fin into mixing drums uses a spiral fin mount rail track adapted to be fixed to the interior surface of the mixing drum. A locking tab locks the upper part of the rail track into the fin structure.

Abstract: The disclosure describes a packing control system for a rear loading, rear discharge refuse packing body that enables adjustability in the overall weight distribution of the packed refuse. The packing density control system involves controlling the resistance of the packing/ejection panel against which refuse is packed in a rear loading refuse collection truck body so that the force necessary to cause the panel to retreat toward the front of the truck as refuse is packed in front of it can be varied in accordance with the desired density profile of the load as it is packed.

Abstract: An automated auxiliary axle deployment control system for a load-hauling vehicle having a time-variable payload and one or more fluid-operated auxiliary support axles comprising one or more load sensing devices for determining the payload distribution of the vehicle in real-time. One or more automatically operable pressure modulation valves adjusts the pressure applied to the one or more auxiliary axles to adjust the load carrying capacity thereof based on payload distribution. A signal processing system receives input signals from the one or more load sensing devices and produces output control signals for operating the pressure modulation valve(s).

Abstract: A collection vehicle including a material handling system, storage body, compaction system, storage system, and dump system all of which have contact surface areas, wherein the surface areas are self-lubricating. The surface areas may be found in the vehicle's fluid biased cylinder bushings, tailgate hinges, storage body pivot joints, articulated joints, rotation joints, and slides. The self-lubricating, low friction, surface areas reduce wear and repair associated with conventional collection vehicle.

Abstract: Loading mechanisms for front loading refuse trucks provided with fluid cylinder operated lift arms and associated fluid cylinder operated lift forks are provided with an improved operating system which allows the lift forks to attain one working position limit for tipping containers and an additional stowage position limit allowing the truck to travel with the arms fully raised.

Abstract: A control and safety system for coordinating movement of multiple hydraulic cylinders to reciprocally rotate a truck-mounted refuse compacting arm. The system includes a logic board controller in communication with a cam and switch arrangement mechanically linked to the rotating arm. Signals from the switches indicate the position of the arm to the logic board which responds by operating directional control valves to regulate movement of the cylinders. A pressure switch is activated to rotate the arm in the opposite direction if the arm is prevented from reaching a limit switch.

Abstract: Steerable tag axle assemblies include an axle mounting lever carrying a wheel on a stub axle and either a kingpin pivot or a spherical bearing pivot for laterally turning the wheel. The lever pivots between a stowed position and a deployed position where lateral forces from the ground urge the wheel to follow the vehicle. In one embodiment, a kingpin pivot connects the stub axle to the lever and a tie rod maintains alignment of the pair of stub axles. In another embodiment, a kingpin pivot connects the lever to a pivoting shaft attached to the vehicle. The shaft turns as the lever moves between the deployed and stowed positions, and the lever pivots laterally at the kingpin pivot to turn the wheels. In another embodiment, a spherical bearing is carried by a spherical bearing mount securely attached to the vehicle. The bearing engages the lever in a bearing cavity, such that the lever pivots laterally and between the stowed and deployed positions on the bearing.

Abstract: A vehicle mounted hydraulic system is provided with a flow control system that allows and maintains sufficient fluid flow through the pump, regardless of pump speed or fluid usage requirements by the hydraulically operated devices, to prevent cavitation or undue pump wear.

Abstract: An internal safety valve for preventing the discharge chute from rapidly falling due a sudden loss of hydraulic fluid pressure. A safety valve assembly for use in a hydraulic cylinder consisting of a safety valve located in the barrel of a hydraulic cylinder. The moveable piston of the hydraulic cylinder has a cavity for receiving the safety valve therein. The safety valve is actuated when the flow leaving the chute lift cylinder exceeds a predetermined flow. The valve immediately stops the hydraulic fluid from leaving the chute lift cylinder maintaining the position of the discharge chute.
