摘要:
An earth working machine for removing the surface layer of a paved surface or soil includes a rotor assembly having a drum (39), a plurality of bit holders (100) secured to an outer periphery of the drum and a plurality of cutter bits (160) one being positioned in each of the holders. Drive means are provided for rotating the drum, and the drum is massive enough and rotates at a high enough velocity to have a kinetic energy greater than 117 J/cm of drum width whereby the surface layer of the ground is sufficiently removed.

A vacuum box in fluid communication with a tractor that removes coatings from surfaces. The vacuum box includes a vacuum inlet in fluid communication with a source of negative pressure and a debris inlet in fluid communication with the tractor so that debris is drawn into and collected within a hollow interior of the vacuum box. A water outlet provides a drain for water that collects within the vacuum box. A sloped false bottom wall is disposed within the hollow interior so that debris collects atop it. The vacuum box is emptied by draining water from it, followed by opening a door formed in the vacuum box at the lower end of the sloped false bottom wall so that the collected debris slides down the false bottom wall and out the door into a debris receptacle.

Bei einer selbstfahrenden Baumaschine (1) zum Bearbeiten von Bodenoberflächen (2), mit einem Maschinenrahmen (4), mit einem Antriebsmotor (6) für den Antrieb von Fahreinrichtungen (8) und von Arbeitseinrichtungen, und mit einer anhebbaren, von einem Walzenantrieb (10) angetriebenen, und von diesem entkoppelbaren Fräswalze (12) zum Fräsen der Bodenoberflächen (2), wobei die Fräswalze (12) in eine angehobene Position verlagerbar ist, wenn sie nicht im Fräsbetrieb ist, ist vorgesehen, dass die Fräswalze (12) im angehobenen Zustand bei einer Fahrtrichtung, bei der die Drehrichtung der Fräswalze (12) mit der Drehrichtung der Fahreinrichtungen (8) übereinstimmt, mit dem Antriebsmotor (6) gekoppelt bleibt und dass eine Überwachungseinrichtung (14) einen Abstand der Fräswalze (12) zur Bodenoberfläche (2) überwacht und die angehobene Fräswalze (12) von dem Antriebsmotor (6) entkoppelt und/oder die Fahreinrichtungen (8) von dem Antriebsmotor (6) entkoppelt und/oder den Maschinenrahmen (4) anhebt und/oder ein Alarmsignal erzeugt, wenn die Überwachungseinrichtung (14) ein Unterschreiten eines vorgegebenen Abstandes detektiert.
摘要:
An apparatus for erasing a road marking on a road lane comprising a chassis adapted to travel over the road lane; a heating source mounted to the chassis for directly or indirectly applying heat to the road marking; and a positively driven rotatable brush mounted to the chassis. The brush has bristles contactable with the road marking and adapted for removing it, when heated, from the road. Indirect heating of the road marking can be accomplished by first heating the bristles of the brush.
摘要:
A method of removing a thoroughfare marking (12) from a thoroughfare surface (14) involves creating a bond with the thoroughfare marking (12) that is greater than the bond between the thoroughfare marking (12) and the thoroughfare surface (14) to enable the thoroughfare marking (12) to be removed from the thoroughfare surface (14).
