Operating Principle
u Wheel Loader Weigher is a dynamic weighing and auto-totalizing equipment installed on wheel loader.
u 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. The operator can judge if the present Single-bucket-loading-weight is valid according to the alarm messages, and confirm the last bucket’s loading weight according to the negative deviation value.
System Configuration
u 1 Weighing indicator with thermal printer.
u 1 Position sensor.
u 2 Oil pressure sensors.
u 2 Plate type three-way joints.
u 1 Mounting fitting.
System Accuracy
Accuracy Grade: III.
Verification Accuracy of Weighing Indicator: 0.02%.
