SUPMETER Wheel Loader Electronic Scales, Weighing Pounds Weighing display Control System For Wheel Loaders
Wheel Loader Weigher is a dynamic weighing and auto-totalizing equipment installed on 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. 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.
Each set contain:
1pcs Weighing indicator with thermal printer.
1pcs Position sensor.
2pcs Oil pressure sensors.
2pcs Plate type three-way joints.
1pcs Mounting fitting.
Applicable Wheel Loaders
Suitable for the wheel loader series with loading capacity 1~12t.
