ABSTRACT:
This invention relates to a platform which can be displaced relatively to the frame side members of a load-carrying vehicle and which in the unloaded state is situated at the theoretical center of gravity of the vehicle load. A load placed on the platform results firstly in an increase in pressure in a tipping cylinder disposed at the center of gravity of the vehicle load and secondly a torque about the theoretical center of gravity of the vehicle load if the center of gravity of the load does not lie thereat. A signal proportional to such torque then controls a platform-displacing system to displace the platform towards the theoretical center of gravity of the vehicle load. The pressure rise occurring in the tipping cylinder forms an indication of the weight of the load and can then be noted and recorded.
