A sweeper including a mat for sweeping a ground surface by moving the mat over the ground surface in a direction of travel substantially transverse to a leading edge of the mat, the mat having at least one slot extending therethrough and disposed transversely relative to the direction of travel whereby in use of the mat debris can pass through the slot over a trailing edge of the slot to collect on an upper surface of the mat, wherein the sweeper includes a cover over the mat for trapping debris on said upper surface of the mat.

A self-propelled object-gathering apparatus includes a chassis, a drive system coupled to the chassis and configured to traverse the apparatus over a surface, and a receptacle coupled to the chassis. The apparatus also includes a sweep assembly coupled to the chassis and rotatable with respect to the chassis. The sweep assembly is configured to transfer objects from the surface into the receptacle by mechanical action on the objects, and without the use of negative pressure or vacuum suction acting on the objects during the transfer, in response to rotation of the sweep assembly.

A vehicle includes a frame and a debris hopper including a door disposed along a side of the vehicle. The vehicle also includes front and rear lift assemblies supporting the debris hopper on the frame and configured to lift and tilt the debris hopper relative to the frame. Each lift assembly includes a transverse support mounted across the frame. A lift arm including a first end and an opposite second end, with the first end of the lift arm pivotably coupled to one end of the transverse support. A leg extending below the debris hopper and disposed proximate the door, with the second end of the lift arm pivotably coupled to one end of the leg opposite of the debris hopper. A first fluid actuator extending between the transverse support and the lift arm, and a second fluid actuator extending between the lift arm and the leg.

A mechanical sweeping mechanism removably affixed to existing ground service equipment (GSE) for the collection and removal of foreign object debris (FOD) in a removable hopper. Movement of a GSE vehicle rotates the independently suspended drive wheels, transmitted by gears/pulleys and chain/belts to power a cylindrical bristle, spinning in the opposite direction of travel, to collect and funnel FOD via a ramp into a removable hopper. Bristle height is adjustable. At least one magnet and skid plate remove metallic FOD.

A raised pavement markers removal vehicle system and method for the removal of raised pavement markers from a roadway. As the vehicle is driven along a roadway, a grinder unit alongside the forward portion of the vehicle grinds away the raised pavement markers to be removed. A sensing unit senses the relative lateral positions of the grinder unit and the upcoming raised pavement markers to be removed. A controller receives position information from the sensing unit and sends appropriate commands to an alignment adjuster to match the lateral position of the grinder unit to the lateral position of the upcoming pavement markers to be removed. After removal by grinding, the debris from the removed raised pavement markers is swept from the roadway into a sweeper-hopper unit for transport to a suitable unloading place. A warning board mounted at the rear of the sweeper-hopper unit provides a visual warning to other users of the road.

A first work tool arm is rotatably attached to a frame or reference structure, a second work tool arm rotatably attached to the first work tool arm, and a work tool attached to an end of the second work tool arm. An actuator and a spring are each rotatably attached to the second work tool arm and configured such that separate movement of the first work tool arm relative to the frame or reference structure and movement of the second work tool arm and work tool relative to the first work tool arm are achieved with actuation of the actuator.

A self-propelled object-gathering apparatus includes a chassis, a drive system coupled to the chassis and configured to traverse the apparatus over a surface, and a control system coupled to the chassis. The control system is programmed to detect a bounded operational area, and to guide the apparatus within the bounded operational area. The apparatus also includes a receptacle coupled to the chassis, and a sweep assembly coupled to the chassis and rotatable with respect to the chassis. The sweep assembly is configured to transfer objects from the surface into the receptacle by mechanical action on the objects in response to rotation of the sweep assembly.
