Abstract

The invention relates to a method for verifying the reliability of the payload of a truck by means of a dynamic vehicle scale comprising a plurality of load cells which are arranged behind each other as well as a vehicle identification system; in said method, the vehicle identification system determines the type of vehicle, and the axle pressure data determined by the dynamic vehicle scale are then compared with the data associated with the type of vehicle. The invention further relates to a device for carrying out the disclosed method.

Abstract

The invention relates to an arrangement for measuring the axle pressures of transport vehicles, such as commercial trucks, railway cars, and the like, in which load cell modules for dynamically measuring axle pressures is provided in a recess of the roadway or on the rails. In order to enable rapid and precise measuring and simple recalibration of the dynamic measuring modules, modules (4, 4'", 34') for static, calibrated measuring of the axle pressures are connected upstream or downstream of said dynamic measuring modules (4, 4", 34). The time spacing of the maxima of the measurements of the sequentially arranged load cell modules are preferably captured and placed in relation to the rise of the load curve.

Abstract

The invention relates to a device for determining wheel and/or axle loads and/or overall weights of road vehicles driving on roads having road surfaces (17), comprising a measurement section (1) having a plurality of measurement fields (4), each having at least one force detector (10), which is disposed in a hollow body (11), particularly made of metal, for mechanical protection, wherein the force detectors (10) are connected to a data processing system (7), and furthermore detectors (5) for wheels and/or axles and/or vehicles are provided in the regions in front of and behind the measurement section (1), wherein the hollow body (11) is divided in the longitudinal direction into an upper and a lower limb (12, 16), (with respect to the load direction), by a joint (14), particularly a continuous joint, and the upper and lower limbs (12, 16) are configured flexibly with respect to each other along the joint (14).
