An operating assembly is provided for advancing and withdrawing the locking collar from the corresponding cylinder rod.

Abstract: A filter vent system and method for separating entrained airborne particulate matter from the conveying fluid is disclosed, particularly as it relates to filling a storage vessel. The filter system employs a simplified, yet more efficient filter cleaning arrangement, in which the entire clean air plenum on the downstream side of a filter array of one or more filter units is periodically pulsed with a large burst or pulse of relatively high pressure air from a single source which rapidly raises the plenum pressure to, in turn, produce a temporary pulsed flow reversal in the filter units which blasts through the filter pores to displace particulate matter collected on the upstream side of all of the filter units alike thereby cleaning or re-generating the filter surfaces.

Abstract: A tailgate system is disclosed that relates generally to vehicles for collecting, transporting and unloading several sorted classes of materials, that may include recyclable materials, in which the truck body is in the form of a generally hollow container mounted on a truck chassis and having an internal volume partitioned into two or more horizontally extending compartments, each equipped to receive, store and discharge or eject materials. The tailgate system is a split system that enables totally separate operation of a tailgate door for each compartment, but which includes automatic latching and maintains a relatively low center of gravity with reference to the vehicle regardless of the position of the doors.

Abstract: A swing-frame auxiliary axle system for a work vehicle having a main frame including spaced chassis rails is disclosed which includes a pivot frame having a pair of spaced pivot arms connected by a common torque tube and each of which is pivotally mounted to a vehicle chassis rail, the spaced pivot arms including at least one tag axle and wheel and a cross member at the other end. An operating system is provided for moving the auxiliary axle assembly between a stowed and a support position. An independent modular arm pivot joint and attachment system pivotally mount each of the spaced pivot arms to a corresponding one chassis rails. The operating system also has a tag lever fixed to the torque tube and a hydraulic operating cylinder having a rod end journaled about an independent modular tag lever pivot joint and attachment system, connected between the rod end and the tag lever removably attaching the cylinder rod to operate the tag lever.

Abstract: A versatile system for seizing, tilting and dumping refuse containers is disclosed that includes a maneuverable, multi-position container grasping device attached to a refuse collection vehicle for handling curbside containers during collection efforts and emptying the containers at a plurality of positions relative to the vehicle charging hopper. A container grabbing mechanism is also disclosed.

Abstract: A container handling system is disclosed, including subsystems for accessing, grabbing, lifting and tipping collection containers into the charging compartment of a collection vehicle, or the like, and thereafter returning emptied containers to their pick up locations. The invention includes an automated, short radius pivot arm capable of operation in close quarters which may further be mounted to and operated by means of a hydraulic rotary actuator. Electronic control is also provided.

Abstract: Side-loading refuse vehicles are disclosed including an offset or recessed hopper section having at least one recessed side which accommodates a loading bin or bucket which is moveable between a lowered position and a raised dumping position. Followers attached to the bucket on each end are engaged in candy cane shaped guide channels situated at the front and rear of the hopper. The guide channels are angled away from the base of the hopper and curved into the top of the hopper to guide the bucket in an angled and arcuate path over the sidewall of the hopper which is built to accommodate the bucket. In some embodiments, a bin handler is built in to the bucket or an automated arm is provided for dumping refuse cans or containers directly into the hopper. The refuse vehicles may have side-loading buckets on one or both sides of the vehicle and the vehicles may be single or multiple compartment vehicles.

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: An auxiliary axle system for a work vehicle is disclosed including a pair of spaced arms pivotally mounted to the vehicle, at least one tag axle and wheel and a cross member and a latch pin carried on one arm. An operating system for moving the auxiliary axle assembly between a raised stowed position and a ground engaging support position is provided with a modular latch mechanism for retaining the auxiliary axle assembly in the elevated position by containing the latch pin. The modular latch mechanism is carried on a base plate mounted as a unit through adjustable bolt slots behind an existing vehicle metal structure so that only a hook device extends beyond the plate.

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.
