Abstract
A transportable cleaning device is proposed, which can be used to clean marking elements laid in the area of traffic surfaces and which includes a cleaning vehicle equipped with castor wheels that allow vehicle movement over the marking elements. The cleaning device is equipped with a laser cleaning device which includes a laser radiation output unit located on board the cleaning vehicle from which laser radiation can be emitted to perform a cleaning process, which can be generated by a laser of the laser cleaning device. A handle on the cleaning vehicle enables it to be guided in a targeted manner over the marking elements to be cleaned.
Claims27
A transportable cleaning device for cleaning marking elements laid in the area of traffic surfaces, comprising:
- a cleaning vehicle that can be guided by hand and comprises a handle for pe the vehicle, a plurality of castor wheels in the area of a bottom of the vehicle that enable a vehicle movement over the marking elements to be cleaned, and a laser cleaning device which comprises a laser designed to generate laser radiation and a laser radiation output unit located on board the cleaning vehicle and participating in its vehicle movement, wherein the laser can generate laser radiation which emits from a laser radiation exit area of the laser radiation output unit and can be directed in the area of the bottom of the vehicle to remove contaminants from marking elements located below the cleaning vehicle.
