Construction machine and method for operating a construction machine

Abstract

The invention relates to a construction machine, comprising a carrier device, a mast which is in particular configured as a leader, and an articulation device, with which the mast is adjustably mounted on a front side of the carrier device, wherein the mast is adjustable between an operating position, in which the mast is arranged upright, and a lying down position, in which the mast is arranged in a lying down manner, wherein the articulation device comprises two support rods, arranged substantially in parallel with one another, for forming a parallelogram arrangement, which rods are each pivotably articulated to the carrier device on the one hand and to a kinematics stand on the other hand, which stand is mounted on the mast so as to be pivotable about an articulation axis, two support cylinders, which are pivotably articulated, on the one hand to the kinematics stand and on the other hand to the mast, and at least one actuating cylinder, which is configured for adjusting the parallelogram arrangement and thus for pivoting the kinematics stand relative to the carrier device. It is in accordance with the invention that the articulation device is configured to pivot the mast out of the upright operating position, forwards into the lying down position, in which the mast is arranged in front of the front side of the carrier device and extends forwards away from the carrier device.
