TILT ROTATOR Calibration

TILT ROTATORS Introduction

  • A tilt rotator is connected between the excavator's arm and the bucket and can be compared to a wrist that allows the operator to tilt ( average up to 55 degrees) and rotate the bucket or other tool infinitely in both directions at the same time.
  • These two functions provide three-dimensional positioning easily and accurately, increasing your efficiency and productivity.
  • The tilt rotator is connected directly to the excavator's arm or beneath the excavator's quick hitch.
  • The tilt rotator is then connected to the excavator's hydraulics and electrical system.
  • Signals from the joystick and the control unit are received by solenoid valves on the tilt rotator thus controlling the function selected.

TILT ROTATORS Installation

  • The installation is today performed by the 3rd Party; Label or independent certified installer technician.
  • Once it is mounted, we can proceed to our installation including connection to this system.
  • The installation generally consists in routing a cable connecting the sensor of rotation system to ours. We connect it to our MC-i4 thorough CAN2. Steelwrist has a gateway, Engcon has c2c unit,..

Calibration steps: example with Engcon

  • Prior to proceeding with calibration of the tilt rotator, try to calibrate the machine first with a standard bucket.
  • This allows you to get filtered the possibilities of solution in case of fail with bucket teeth position check.

Step 1 Dogbone horizontal

  • Get the dogbone balanced with a spirit level on pivot points

Step 2 Dogbone vertical

  • Get the dogbone balanced with a spirit level on its frontal part

Step 3 Rotator horizontal

  • Get the tilt balanced with a spirit level on its horizontal side

Step 4 Rotator tilt balance

  • Place magnet to center of the pivot point and take note of the distance with the help of a measuring tape up to horizontal level of the rotation axis of the tilt movements.

Step 4 tips

  • Preparation of center points of lateral positioned pivot points
  • Make a deep point (hit with hammer and bore to make it deeper) so you will be able to put the magnet on the center of pivot point with best accuracy

Step 5 tilt horizontal position set

  • Place spirit level to get it balanced and give instruction to operator

Step 6 tilt vertical position set

  • Place spirit level to get it balanced and give instruction to operator

Step 7 Ensure fixing rotation position zero

  • Place measuring tape to both sides in order to set the zero position mark as rotation reference and give instruction to operator ( to find out average equal distance)

Step 8 Measuring the offset

  • Try to find and measure to the center of rotation system. In this case we found a mark to show the center which coincides well with measurement done

Step 8 tips

We have asked Engcon to provide measurements so we could avoid to measure the offset. Ask Professional Service to get these. All brands have to provide this information, this is in fact one of Topcon requests to insure accuracy quality for measuring the position of any bucket teeth. We then erase human error. Please ask Topcon Europe ( Professional Services) to get the table values ( offsets values for each model for each brand )

Step 9 Standard calibration of a bucket part 1

  • Measure the bucket dimension 1

Step 9 Standard calibration of a bucket part 2

  • Measure the bucket dimension 2
  • BUT for tilt bucket we must take 2 measurements and calculate the average
