Installation of Position Sensor
Position sensor includes two modules:
- Proximity Switch Module: Main Mounting Plate with a chute for length adjustment, Sub-mounting Plate with a chute for angle adjustment, Upper Proximity Switch and Lower Proximity Switch [Detecting Distance: 1~8mm].
- Magnet Module: Thread Pole, Weld-nut, Tight-nut, Nylon Block, Magnet Block.
1: Lift-arm Seat; 2: Lift-arm; 3: Main Mounting Plate; 4: Sub-mounting Plate; 5: Weld-nut;
6: Thread Pole; 7: Nylon Block; 8: Fastening Nut for Position Ajustment; 9: Magnet Block; 10: Upper Proximity Switch; 11: Upper Proximity Switch; 12: Fastening Nut for Length Ajustment; 13: Fastening Nut for Angle Ajustment.
Sensing Distance Adjustment: Adjust the sensing distance between the Magnet Block and the Proximity Switch to 3~5mm.
Suggestion: Install the position sensor on the lift-arm seat and lift-arm which are at the same side that the weighing indicator installed on.
Installation of Oil Pressure Sensor
- 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.
