Construction machine, in particular road construction machine, for example tandem roller, having a vibration-decoupled operator platform structure and having a hitch device
First Claim
1. A construction machine, comprising a machine frame and an operator platform structure which is vibration-decoupled in relation to the machine frame using at least one damping element, and a hitch device for lifting the construction machine, the hitch device being arranged on the operator platform structure, wherein,a travel limiting device is provided, which is implemented in such a manner that, upon lifting of the construction machine via the hitch device, the travel limiting device limits the load of the at least one damping element, prevents excess traction load of the at least one damping element upon lifting of the construction machine, and allows a direct force flow between the operator platform structure and the machine frame.

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.
