         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.

       2.2 System Configuration

¨ 1 Weighing Indicator with Thermal Printer.

¨ 1 Position Sensor.

Related Operation Terms:

² Arm-up: Lift the lift-arm so that the bucket rises.

² Arm-down: Put the lift-arm down so that the bucket goes down to the lowest position.

² Bucket-up: Flip the bucket upward to the limit position.

² Bucket-down: Flip the bucket downward.

² Discharge: Flip the bucket downward for discharging materials.

² Shovel: Shovel materials into the bucket.
