A brief introduction to spindle extension for ground cranes.
Since the start in 1970, we have acquired almost 50 years of experience in what is important for operational reliability, easy installation, and worked actively with continuous development based on all the good feedback we receive.
Our telescopic spindle extensions for ground cranes are now color-coded at the top.
Color coding:
- Blue for water
- Red for drains
- Yellow for gas
- Green for acid-proof design
With this color code marking, you will easily and clearly see which installation is located underground.
