ABSTRACT:
A stone-laying machine is provided have laying tongs fixed to a boom arm which can be controlled from the driver's cab. The front and rear wheels of the machine are rotatable about points of rotation lying on a longitudinal center line behind the front axle and in front of the rear axle, respectively. In order to prevent overturning of the machine when the front and rear axles are swivelled in relation to one another, the center of gravity of the machine is altered with respect to conventional stone-laying machines by relocating the boom arm relative to the front axle.
