ABSTRACT:
A construction machine for machining floor surfaces, wherein the machine includes a milling roll having a plurality of tool holders on a surface thereof. A tool, especially a straight shank tool, is received in a tool receiving element of the tool holder in an exchangeable manner. With this invention it is possible to change the tool in one such construction machine in a simplified manner. Thus, the milling roll is associated with a tool changing device, and the tool changing device dismounts each tool from the tool holder and/or mounts each tool in the tool holder.
