A mobile weighing system for use on a truck or trailer to weigh a load carried by the truck or trailer. A load support frame supports a load and is positioned over the frame of the truck or trailer. A plurality of weighing cells are mounted over the truck or trailer frame in such a manner as to bear an approximately even distribution of the load. Each weighing cell comprises a lifting mechanism having an extended position and a rest position, a vertically disposed tension load cell and a linkage assembly coupling the lifting mechanism and the load cell to cause an upward force on a top end of the load cell when the lifting mechanism is extended. The bottom end of the load cell is attached to the support frame so that the support frame is suspended by the load cells when the lifting mechanisms are extended. The lifting mechanisms and linkage assemblies of the weighing cells are attached to the truck or trailer frame. A lock down mechanism integral to the load cells secures the load support frame when the lifting mechanism is in a rest position.
