Construction machine in which an engine carrier is connected to a tool carrier via a joint to form an articulated running gear, the engine carrier having at least a first chassis axle and an engine for driving the construction machine and the tool carrier having at least a second chassis axle. The construction machine additionally has a driver's cab which is arranged between the engine and tool carrier and is attached, in accordance with the invention, displaceably to the tool carrier in such a way that it can be displaced along the longitudinal axis of the tool carrier and can thus be varied in its height position in such a way that it can be raised, for operating the construction machine, into a working position and lowered, for transporting the construction machine, into a transportation position.
