ABSTRACT:
A weight load indicator for registering the weight of a load as it is applied to a truck, the truck includes a frame and a wheel suspension connected to the frame. The load indicator device comprises a housing having a piston rod chamber fixed to the frame, a piston rod with a first and a second end engage the chamber with the second end extending from the chamber and the second end is within the path of movement of the truck suspension as a load is applied to the truck. The first end of the rod is free to move toward the frame within the chamber in response to the load applied to the truck. A sensor is mounted on the housing. The sensor includes a swingable arm within the path of movement of the first end of the rod. An electrical circuit, including a gauge, is provided in series with the sensor for detecting movement of the swingable arm as the first end of the rod moves upward toward the frame within the chamber. In this manner, the user is able to determine the weight of the load applied to the truck.
