Change Komatsu undercarriage: rubber to steel

This Komatsu D21a recently arrived in our workshop for replacing the running gear on rubber tracks to a steel running gear.

For this, several things had to happen before the steel chains would fit on the machine:

  • extension of the chassis
  • extending the push rod of the idler
  • moving the front top rollers forward
  • placing an extra carrier roller on each side

Our workshop is also fully equipped for unusual matters, and our team is ready for all possible challenges.
