摘要： For measuring the weight of a load of a load-carrier of at least one vehicle, which load-carrier is supported by at least one spring unit on a mobile substructure of the vehicle, weighing apparatus is provided with means for measuring the elastic deformation of the spring unit or units under the load. The measuring means includes a reference object mounted on the load-carrier. To avoid vulnerable equipment on the vehicle and to improve information obtained, the measuring means includes electrical observation means for non-contact observation of the position of the reference object. The electrical observation means being free of the vehicle.
