2. Brief Introduction
2.1 Operating Principle
Wheel Loader Weigher is a dynamic weighing and auto-totalizing equipment installed on wheel
loader without changing the original structure of wheel loader.
When the lift-arm of wheel loader lifted to a certain height, the position sensor will trigger the
weighing process, and the weighing indicator will collect the oil pressure signal from lower and upper
oil chambers of arm-lifting oil cylinder. After signal processing and compensating, Single-bucket
-loading-weight will be got and totalized to Totalized Loading Weight automatically, and the
Deviation Value between Totalized Loading Weight and Setpoint, alarm messages will be displayed.
The operator can judge if the present Single-bucket-loading-weight is valid according to the alarm
messages, and confirm the loading weight of last bucket according to Negative Deviation Value for
avoiding overloading. After Totalized Loading Weight reached setpoint, the operator should stop
loading process, save and print Loading Records.
