1. Safety Precautions
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.
Prohibit using the product under dangerous environment
Prohibit using the product under the dangerous environment with combustible gas and
explosive dust. If you have this need, please use our explosion-proof products.
Avoid using the product under overheated environment
Make sure that the weighing indicator works under the environment with allowed temperature
range to get good performance and long working life.
Please keep the product away from direct sunlight.
Installation & Power Supply of Weighing Indicator
Weld the mounting bracket of the weighing indicator firmly on the metal frame of the shovel
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 power supply 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 calble and position sensor signal cable should be laid in flexible
pipe for protection, and fix them with nylon strip.
Try to keep signal calbles 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.
Although the weighing indicator is made of the lead-free components, after used in the
industrial environments, it’s possible to be polluted. So, 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
Shovel Loader Weigher is a dynamic weighing and auto-totalizing equipment installed on shovel
loader without changing the original structure of shovel loader.
When the lift-arm of Shovel Loader is lift to a certain height, the position sensor will trigger the
weighing process, and the weighing indicator will collect the oil pressure signals from lower and
upper oil chambers of arm-lifting oil cylinder. After signal processing and compensation,
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 Record.
2.2 System Configuration

5.1.4 Installation of Oil Pressure Sensor
1. Intallation 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 shovel loader
should be kept at flameout state.
Put a bucket under the oil connecting ports that will be
dismounted for oil collecting.
If the shovel loader has worked for a long time, the oil
temperature in the bucket-lifting cylinder will be very high.
Please let the shovel loader at flameout state for some time
before dismouting to avoide 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
shovel 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: 19mm/21mm] and the oil
tube connector on the arm-lifting oil cylinder by the
lengthened screw rods which is about 20mm longer than
original screw rods.
4. Check Oil Passage
Start shovel 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.

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