Abstract
The present invention relates to a construction machine having an operator's cabin whose cabin structure which is made reinforced serves the protection of the operator, with the operator's cabin being supported via a base plate at an operator's cab frame at the machine side. In accordance with the invention, the stiffness of the cabin structure is larger than that of the base plate and/or of the operator's cab frame at least with respect to a lateral force engagement so that in a load case first the base plate and/or the operator's cab frame are deformed.
Claims14
A construction machine having an operator's cabin (5) having a reinforced cabin structure for protection of the operator, with the operator's cabin (5) being supported via a base plate (3) on an operator's cab frame (1) at the machine side, wherein
- the stiffness or strength of the cabin structure is larger than the base plate (3) and/or operator's cab frame (1) at least with respect to a lateral force application, such that on a load application, the base plate (3) and/or operator's cab frame (1) deform first, and
- the operator's cab frame (1), cabin structure or base plate (3) have force-transmitting elements (4) arranged out of contact in a normal operation and in a loading condition, come into contact to transmit force from the cabin structure to the operator's cab frame (1).
