The invention relates to a cleaning device for the dry cleaning of a tunnel, comprising a feeding device for feeding a flow of air to a surface being cleaned, wherein the feeding device has an exit opening, through which the flow of air emerges from the feeding device, and a removal device comprising at least one removal pipe with a free end with an opening for suctioning away direct or trash from the surface with the opening of the free end in a first direction. The feeding device is arranged such that the flow of air from the exit opening emerges from the feeding device in a second direction toward the opening of the free end of the removal pipe and impinges on the surface. The first direction is oriented at an angle between 45 and 80 to the second direction.

A sweeping machine for mounting to a blower is adapted for sweeping debris, e.g., snow, from an area around an obstacle, e.g., fire hydrant. The sweeping machine comprises a rotating brush having an axis of rotation which is horizontal, a frame for the rotating brush, an arm extending from a proximal end to a distal end to which the frame is secured, a blower, and a pivoting mechanism secured to the blower. The pivoting mechanism is adapted to swivel the arm upwardly to lift the rotating brush and to swivel the arm within a horizontal plane to move the rotating brush horizontally relative to the blower. Thereby, the sweeping machine is adapted to sweep debris from the area around the obstacle by the rotating brush toward the blower which is itself adapted to blow the debris away from the obstacle.

A mat washer includes: a body adapted for highway transport; a loading platform adapted to receive a stacked pair of mats from, for example, a forklift, and adapted to pivot the pair of mats to an upright position; a splitter adapted to receive the mats from the loading platform and to separate the mats from one another; a transporter adapted to transport each of the mats longitudinally relative to the body from the splitter; a uniter adapted to receive the mats from the transporter and urge them together; an unloading platform adapted to receive the pair of mats from the uniter and pivot them downwardly for retrieval by, for example, the forklift; and a washing facility disposed between the loading and the unloading platform and adapted to wash the mats.

The invention discloses a traffic road fence cleaning device, comprising a U-shaped main body support frame, the U-shaped main body support frame is composed of a first main body beam, a first main body beam, and a second main body beam, and the first body A first cleaning column and a second cleaning column are provided on the lower side of the side member, a first power system is provided on the upper side of the U-shaped main body, support frame, and a second power system is provided on the upper side of the third body side member. The front side of the U-shaped main body support frame is provided with a drum cleaning system, and a water supply system is provided above the third main body longitudinal beam. The dirt on the surface comes off. The suction pipe collects and treats part of the water mist and dust to prevent secondary pollution. The cleaning roller is responsible for the final wiping and secondary cleaning functions to ensure the cleaning quality of the traffic fence. Efficient and fast cleaning of traffic fences.

The invention discloses a large-scale quick-cleaning device for a display screen, which includes a storage box fixed on a truck, and an upper end surface of the storage box is provided with a lifting cavity with an upward opening, and the lifting cavity is provided with a lifting device for lifting. The device comprises a first motor fixedly arranged at the center of the lower wall of the lifting cavity, and a lifting platform can be slid up and down above the first motor, and a support block is fixedly arranged on the rear side of the upper end surface of the lifting platform. The upper end surface is provided with a turning groove, and a turning plate is rotatably provided between the left and right walls of the turning groove.

A boarding sweeper comprises a cleaning working unit capable of executing cleaning work, a seat portion for seating a user, an operation input unit that allows the user to input a driving operation, a suction unit provided in a vicinity of the cleaning working unit, a battery holder that detachably holds a battery unit, and an air guiding mechanism that guides suction air from the suction unit so that the suction air passes through the battery holder.

The present disclosure provides a material collection system. The material collection system includes a conduit, a vacuum generator coupled to the conduit, an engine powering the vacuum generator, and a container mounted to a chassis of a vehicle. The vacuum generator generates airflow for drawing material into a material inlet of the conduit. The container receives collected material from the conduit. The conduit, vacuum generator, the engine, and the container are supported on a hook-lift frame.

A material collection system is provided. The system can include a vehicle, a conduit, a vacuum generator mounted to the vehicle to develop an airflow and to draw material into the conduit, and a moveable boom mounted to the vehicle to support the conduit. The system can include a control system to control a speed of the vacuum generator.

Systems and methods for a selectively-activated magnetic strip under a vehicle chassis that is powered to pick up nails and other metal debris. The magnetic strip can be selectively activated using an electromagnet powered by the vehicle and controlled by an onboard computer. The magnetic strip can generally be powered on while the vehicle is driving and selectively deactivated based on mapping data to avoid interactions with metallic infrastructure. The magnetic strip can be selectively deactivated based on vehicle parameters, such as vehicle speed.

A material collection system is provided. The system can include a vehicle, a conduit, a vacuum generator mounted to the vehicle to develop an airflow and to draw material into the conduit, and a moveable boom mounted to the vehicle to support the conduit. The system can include a control system to control a speed of the vacuum generator.
