1. Safety Precaution
Lithium Battery Installation
A Lithium battery should be equipped in the weighing indicator. If it is not allowed to be
transported together with the product because of embargo, please make a purchase
according to the model offered by us and install it by yourself.
Application environment
Make sure that this product works under the environment where is accord with the technical
specifications.
Do not open the shell before power-off.
Installation & Power Supply of Weighing Indicator
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.
The power switch of the weighing indicator should be turned off and ensure that the power
cables are not charged before DC24V power connection to avoid short circuit fault.
Please make sure that the inputted voltage is correct before power-on.
Installation of Oil Pressure Sensor
Strictly follow the ‘Safety Precaution’described in ‘5.1.4 Installation of Oil Pressure Sensor’.
Install the oil pressure sensors and plate type three-way joints firmly, and seal them as
prescribed to avoid oil leaking.
Installation of Position Sensor
Install the position sensor according to required position and angle, and adjust Detecting
Distance to 3~5mm.
Cable Laying
Oil pressure sensor signal cable and position sensor signal cable should be laid in flexible
pipe for protection, and fix them with nylon strip.
Try to keep signal cables away from the place with high temperature and possible extrusion,
and reserve enough bending length to avoid being pulled apart.
Environmental Protection
Before the Lithium battery equipped in the weighing indicator being discarded, please
insulate its positive or negative pole, do not put it into fire.
While being discarded as worthless, the weighing indicator should be processed lawfully as
leady industrial waste for environment protection.
Other Notes
The installation, wiring and maintenance should be operated by the engineers with the
relevant professional knowledge and safety operation ability. Although being not described in
this manual, the relevant safety operating procedures and standards should be followed.

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.
2 Oil Pressure Sensors.
2 Plate Type Three-way Joints.
1 Mounting Fitting.
2.3 Applicable Wheel Loaders
Suitable for the wheel loader series with loading capacity 1~12t.

5.1.4 Installation of Oil Pressure Sensor
1. Installation Position
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.
2. Safety Precaution
Using a stable and strong base to support the bucket of the
loader for avoiding accidental injury.
In the process of dismounting and mounting, the wheel loader
should be kept at flameout state.
Put a bucket under the oil connecting ports that will be
dismounted for oil collecting.
If the wheel loader has worked for a long time, the oil
temperature in the bucket-lifting cylinder will be very high.
Please let the wheel loader at flameout state for some time
before dismounting to avoid scalding.
Before dismounting the oil connecting port of the upper oil
chamber, let the bucket-lifting action bar stay at the position of
‘LIFT’ for making the upper oil chamber connect with main oil
tank and relief pressure.
Before dismounting the oil connecting port of the lower oil
chamber, let the bucket-lifting action bar stay at the position of
‘FALL’ for making the lower oil chamber connect with main
oil tank and relief pressure.
When somebody stays in driving cab, do not stay under the
wheel loader for avoiding accidental injury.
3. Installation
Wrap some sealing ribbons on the screw of oil pressure sensor
avoid oil leakage, and install it on the three-way joint firmly.
Fix the three-way joint [thickness: 24mm] and the oil tube
connector on the arm-lifting oil cylinder by the lengthened
screw rods which is about 24mm longer than original screw
rods.
4. Check Oil Passage
Start wheel loader, and lift the lift-arm and bucket with
accelerating for several times.
Check if there is the phenomenon of oil leakage at the oil
connecting ports.
Only after the welding work finished, it’s allowed to install Oil
Pressure Sensors and Proximity Switch for avoiding damage.

18
5.1.5 Cable Laying
Oil pressure sensor signal cable and position sensor signal cable should be laid in flexible pipe for
protection, and fix them with nylon strip.
Try to keep signal cables away from the place with high temperature and possible extrusion, and
reserve their bending length enough to avoid being pulled apart.
