摘要

The invention relates to a construction machine comprising a machine chassis frame (2) in which a milling roller (18) is mounted such that it can rotate. Said milling roller (18) comprises a roller base body (19) which is driven by a milling roller drive device (11 to 15) via a transmission unit (32) and comprises a milling tube (25) that can be coaxially slid onto the roller base body (19) and can be fastened to the same in an exchangeable manner. The outer surface (46) of the milling tube is equipped with cutting tools. According to the invention, the milling tube (25) comprises fastening elements (28) which radially project from the inner surface (44) and with which the milling tube (25) can be fastened in a rotationally fixed manner to the roller base body (19) or to a part that is connected to the roller base body (19).
