2 Introduction
The Loadrite Force Weighing System measures the weight of loads lifted by
front-end loaders, log loaders, forklift trucks and similar machines that use
hydraulic rams to lift the load. The Loadrite is installed in the cab of the
loading machine and is connected to sensors on the lifting arms.
As the machine raises the load, the Loadrite measures the hydraulic
pressure in the lift cylinders, converts pressure into a weight reading and
displays the result. An electronic trigger device mounted on the lift arms
ensures that the pressure readings are always taken at the same position
on every lift.
The weight of the bucket or forks and associated structures is zeroed out
when the system is calibrated so that only the weight of the payload is
displayed. While operating the loader, the driver can add each weight lifted
to a running total.
