Abstract: A refuse vehicle includes a chassis, an energy storage device supported by the chassis and configured to provide electrical power to a prime mover, wherein activation of the prime mover selectively drives the refuse vehicle, a body for storing refuse therein supported by the chassis, a first hydraulic pump configured to convert electrical power into hydraulic power, a second first hydraulic pump configured to convert electrical power into hydraulic power, and a motor coupled to at least one of the body or the chassis and configured to drive the first hydraulic pump and drive the second hydraulic pump.

Abstract: One exemplary fluid ejection device includes a substrate having one or more layers positioned thereon. The fluid ejection device also includes a fluid-feed path extending through a space which is defined, at least in part, by the one or more layers. The fluid ejection device including methods and structures for managing air and amongst other things gas bubble formation.

Abstract: A locking mechanism for an elevatable lift platform, having a work platform, a scissor-jack and a locking mechanism, is utilized to elevate a chassis for straightening or other repairs. The scissor-jack is contracted by a power actuator, thereby increasing the scissor-jacks' vertical height and elevating the platform. The locking mechanism is comprised of a herringbone lock arm and a lock actuator assembly. The lock assembly is positioned on the power actuator and comprises a two locks, a pneumatic cylinder for extending and contracting the locks vertically, and a lock retainer bar for restricting the extension of the locks. The locks incrementally move along the lock arm horizontally as the jacks are contracted or extended. The locks engage grooves located between teeth on the lock arm that prevent the jacks from contracting or expanding. The locks can disengage the grooves if the pneumatic cylinder is activated to release the locks.

Abstract: A vehicle-straightening bench (20) is utilized to apply pulling forces to a damaged vehicle chassis to restore the damaged chassis to an original configuration. The bench includes a vehicle platform (22) with a carriage track (24) having a plurality of carriage assemblies (100) movably received by the carriage track (24). Each carriage assembly (100) supports a pulling assembly (200) for applying the pulling forces. A trapezoidal carriage body (102) of the carriage assembly (100) rolls in the carriage track (24), and the carriage assembly also includes a tower positioning mechanism (104) to hold the pulling assemblies (200) in place while the carriage body (102) is are rolled on the track (24). The carriage assembly (100) also includes a locking mechanism (106) to lock them in place during a vehicle a pull.

Abstract: An expandable handle for a rotational tool having two end segments of a handle. The end segments are rotatably attached to the body of the handle. In one embodiment, the end segments rotate in the same plane. In a second embodiment, the end segments rotate in parallel planes. The first embodiment preferably employs magnets in the end segments to keep such end segments aligned when an expansion of the handle is not desired. The second embodiment preferably achieves this goal by having a channel channel on a first end segment and a complementary extension on a second end segment.
