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.

A method for the operation of a cleaning vehicle, in particular a street sweeper capable of being operated in automated fashion, by a control device. A trajectory is calculated and control commands are produced for a longitudinal guiding and transverse guiding of the cleaning vehicle during travel of the calculated trajectory. Measurement data are received from at least one sensor in order to ascertain a cleaning region. At least one actuator is controlled, based on the received measurement data, in order to position a cleaning device of the cleaning vehicle in the longitudinal direction and/or transverse direction relative to a direction of travel of the cleaning vehicle, in order to clean the cleaning region. A control device, a computer program, and a machine-readable storage medium are also described.

A cleaning vehicle comprises a rolling chassis and a primary power source (13) in the form of a combustion engine which is able and configured to drive the vehicle. A suction installation (30) is provided which has an underpressure chamber (20) and a pump device (31,32,33) coupled thereto. The pump device comprises a primary pump unit (31,32) which draws its input power from the primary power source (13). In addition, the pump device comprises a secondary pump unit (33) which is optionally driven directly by a secondary power source in the form of an electric motor. The secondary power source (33) is supplied independently of the primary power source (13) by an electrical power supply.

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.

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 material collection vehicle may include a vehicle body and a mounting system including a turret sealingly coupled to a boom mounting joint. The mounting system may be used for mounting a telescopic boom assembly. The boom assembly may include a bearing seal to provide for sealed fluid communication through the boom assembly. The mounting system and boom assembly may form a sealed fluid flow path from the boom assembly to the vehicle body through the mounting system.

An apparatus for clearing around an associated stationary object includes a housing having a top wall, a side wall, and at least one opening extending through the side wall. At least one paddle member is mounted to and extends radially outward from an exterior surface of the housing. The paddle member is adapted to clear around the associated stationary object. The apparatus further includes a plurality of elongated cables mounted to a support that is selectively secured to an interior surface of the housing. The elongated cables are adapted to clean around the associated stationary object.

The present document describes a device for clearing an area around an elevated object. The device comprises: a main frame; a blower device operably mounted on the main frame for blowing high flow air towards the area around the elevated object; and a sweeping device operably mounted to and extending from the main frame for clearing the area around the elevated object. The present document further describes a method for clearing the area around an elevated object.

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.

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.
