This dynamic on-board Excavator Scale System that fits any make or model of excavator. The material in the bucket is weighed as the operator lifts the boom while loading a truck.
The scale display will show the individual bucket weight and a running total of the amount that has been loaded on the truck. The load will be stored and can be downloaded via the built in USB port with a memory stick for further processing at an office PC.
A printed receipt can be generated if the optional printer is installed. It is also possible to send an SMS message to a designated cellular number that contains the load information. Both the printing and SMS messaging are optional for the Excavator Scale system.
Lists of customers, products, trucks and locations can be uploaded to the display using the USB port with a memory stick. Load lists can be downloaded via the USB port with a memory stick to be further processed at an office PC. The files can be viewed and edited in e.g. MS Excel or Notepad.
The Excavator Scale has a backup and restore function for most of the data including calibrated attachments, event logs and lists of customers and products. |

Advantages:
·Provides an operational and
management record of
loading.
·Eliminates return trips from
the weighbridge of
over/under loaded trucks.
·Gives accurate results when
weighing on rough or uneven
ground.
·Reduces weighbridge queues.

| A quick look at calibration of the Excavator Scale System. |
| Procedure for Basic Calibration: |
| 1. Fill the bucket with material close to a typical load; the load must be evenly distributed. A known weight can be used if its centre of
gravity corresponds to the centre of gravity of a symmetric load in
the bucket. Note! Operate the arm and boom to ensure that excess material
will fall off the bucket prior to starting the calibration procedure. Avoid loosing material during calibration! |
| 2. Place the machine on level ground with the boom horizontally. |
| 3. Enable the calibration switch underneath the Main unit. |
| 4. Start LOADTRONIC 3E, Open Main Menu – Calibration
Functions –Basic Calibration. |
| 5. Set the arm to 25deg.
Note! Position the bucket in the same position as during taring
for that arm angle. |
| 6. Press Start. |
7. Operate the boom in a steady speed of approximately 3deg/s according to the instructions on the display: Lower – Lift.
The blue bar in the display illustrates the position of the boom, refer Figure 4-8. |
| 8. Press the bucket onto ground for a short time to relieve the
pressure in the cylinders. Do not loose material. |
| 9. Set the arm to 5deg. Note! Position the bucket in the same position as during taring for that arm angle. |
| 10. Press Start. |
| 11. Operate the boom at a slow speed according to the instructions on the display: Lower – Lift. The blue bar on the display illustrates the position of the boom. When the basic calibration is OK, LOADTRONIC 3E asks for the reference weight, refer Figure 4-9, which is the weight of the material in the bucket, refer chapter 4.2.1 for details. 12. Set the reference weight by pressing the up- and down arrows, or type the weight using the keypad. Press OK to complete. 13. Perform test weighing. Smaller adjustments can be done, refer chapter 4.3. When basic calibration is not OK, 'Not accepted' will show on the display. The probable cause is uneven movements and/or shaking of the lifting mechanism, or too high/low lifting speed. |
| |
| 4.2.1 Reference weight Alternative 1: The reference weight is known with accuracy within 0.5 %; use a weigh-bridge or approved weights. The calibration weight must be close to a typical load. |
| Alternative 2: If the load material can not be weighed within the required accuracy, you can estimate the weight as carefully as possible. Set the value. When the basic calibration is done, the calibration must be adjusted by performing a test with an accurately known weight, e.g. a stone, before the calibration is complete. |

| Installation, Warranty, and Support : On site installation is available Nationwide. The Standard Warranty will apply to the Excavator Scale System. Support is available at the main contact number 24/7/365. At ApexEgroup, we take great pride in being able to offer our customers with the best support in the industry. |
What
you need to install scale:
• (Provided) Two T-fittings, one for piston
and one for the rod side of the cylinder are required or any modifications
to the tubing to adapt the pressure sensors; both will be inline
of the pressure lines from the cylinder area. The pressure sensors
supplied are equipped with ¼” BSSP threads. A ¼ NPT
to ¼ BSSP adapter comes with kit.
• The
customer to have and any special brackets required to mount the display in the
cab in the event the cab has limited space for mounting. A standard bracket
kit is supplied with the kit.
What
you need to calibrate scale:
• Customer
is responsible for known weight! Calibration of this system requires a known
weight Or A weighbridge and truck will be needed to verify the known weight of
the material used for calibration.
Note: The
weighing system is hydraulic based. The hydraulic system on the
machine MUST be free of any leaks or defects. Mechanically, the
machine must be sound. Free of play in boom upper structure. Any
discrepancies in the areas will result in improper operation of
the weighing system. |
What
You Should Know!
| What
you should know about Hydraulic system. |
| • |
Do
not install scale systems on any equipment that are
poorly maintained. |
| • |
Hydraulic
leak can degrade the performance of any system. |
| • |
Under
powered equipment can cause hydraulics to surge. This is caused
by over sized attachments. |
