A brush (1) intended for industrial use comprises one or more bristle bunches formed by a plurality of elongated bristles, one or more cassette elements having said bristle bunches, and a cassette element holding member (3) at which said cassette elements may be removably secured. At least one of said cassette elements comprises a body, one or more recesses configured to receive said bristle bunches therein, and a securing wire configured to secure said bristle bunches in said recesses. Said at least one cassette element further comprises means configured to counteract movement of the bristles of a bristle bunch with respect to each other and/or with respect to the securing wire.

An apparatus is provided which includes a processing circuit and a plurality of sensors connected to a vehicle, where at least one of the plurality of sensors is positioned on an undercarriage of the vehicle. The plurality of sensors can detect variations in a road on which the vehicle is traveling. The plurality of sensors can also generate information corresponding to the variations of the road. The plurality of sensors can also transmit the information corresponding to the variations in the road to the processing circuit. The information collected by the plurality of sensors may then be used to augment a driving capability of the vehicle.

A vehicular sweeping machine includes a frame and a broom assembly that is mounted to the frame. The broom assembly includes a broom enclosure and a broom that is mounted within the broom enclosure. A plurality of links are pivotally mounted between the frame and the broom assembly. These links are adapted to permit the broom assembly to move upwardly and downwardly with respect to the frame. The vehicular sweeping machine also includes a broom conveyor having a lower end that is disposed within the broom enclosure.

Apparatus and techniques for indicating loading of filters are described. The apparatus and techniques are especially (although not necessarily exclusively) useful in connection with automatic pool cleaners with on-board filters and pumps. Indicators identifying clogging of the filters may be included in or on the cleaners or transmitted as information to users for further action.

An apparatus is provided for cleaning a floor, and in particular a barn floor having a lower portion and an elevated portion that intersect to form a curb. The apparatus is attached to a vehicle that travels in a longitudinal direction. The apparatus includes a scraper for scraping the lower portion of the floor. The scraper is pivotally attached to the vehicle for adjusting a transverse position of an end of the scraper into abutment with the curb. The apparatus also includes a cleaning head for moving material from the elevated portion of the floor. The cleaning head is attached to an arm. The arm is pivotally attached to the scraper for adjusting a transverse position of the cleaning head into alignment with the elevated portion of the floor. The cleaning head is actuated to sweep material transversely into the path of the scraper as the vehicle moves in the longitudinal direction.

A vehicular sweeping machine includes a frame and a broom assembly that is mounted to the frame. The broom assembly includes a broom enclosure and a broom having a generally cylindrical tube with attached bristles that is mounted in the broom enclosure and adapted to rotate about a generally horizontal axis. The broom assembly also includes a material presentation system that is adapted to move material on the roadway into contact with the broom in the form of a windrow that is located generally in front of the center of the broom assembly. The sweeping machine also includes a broom conveyor having a lower end that is disposed within the broom enclosure.

A mobile vehicle, a ground treating equipment and an orientation adjusting method thereof are provided. The ground treating equipment includes a frame, a ground treating unit, a connecting rod set, a connecting rod driving unit, a rotation driving unit, two pressure sensors and a controller. The ground treating unit is mounted at the frame. Two ends of the connecting rod set are connected to the frame and the mobile vehicle. The connecting rod driving unit is mounted at the connecting rod set for adjusting the orientation of the connecting rod set. The rotation driving unit is mounted between the frame and the connecting rod set for driving the frame to rotate relative to the connecting rod set. The pressure sensors are mounted at the frame for sensing two pressure values between the frame and ground, or the pressure sensors are mounted at the rotation driving unit for sensing two pressure values while the frame is driven to rotate clockwise and counter-clockwise. The controller is configured to control the connecting rod driving unit and the rotation driving unit for changing the two pressure values.

This invention relates to multi-purpose self propelled surface cleaning machine for road construction and especially to a drivable surface sweeper and scrapper for the removal of overburden and waste materials during road construction. The prime mover has multiple flexible components and does not need to add make-shift components at a later time.
