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.

Weld the mounting bracket of the weighing indicator firmly on the metal frame of the wheel loader driving cab. The installation position should be convenient for operation.
Suggestion: Install the weighing indicator in the driving cab of wheel loader and on the side the door which will not be opened frequently.
The upper oil connecting port and lower oil connecting port of arm-lifting oil cylinder are the installation positions of oil pressure sensors.
Suggestion: Install the oil pressure sensors on the arm-lifting oil cylinder which is at the same side that the weighing indicator installed on.
Install the position sensor on the lift-arm seat and lift-arm which are at the same side that the weighing indicator installed on
There is a thermal printer buillt-in indicator.
If you don't want it, you can connect a printer externally. Please inform us when making order.
