    Patent number: 8602679
    Abstract: The present invention relates to a construction machine having a machine frame and an operator platform structure which is vibration-decoupled in relation to the machine frame via at least one damping element. A hitch device is arranged on the operator platform structure, which is designed for lifting the construction machine. The present invention is characterized in that a limiting device is also provided which limits the maximum load of the at least one damping element upon lifting of the construction machine via the operator platform structure and allows a direct force relay between the operator platform structure and the machine frame while bypassing the damping element. The construction machine is preferably a tandem roller.
