Tunnel high pressure cleaner in the real test!

A newly designed high-pressure tunnel cleaning truck was recently subjected to the crucial final test before delivery. A blocked construction site on the A9 near Kirchdorf an der Krems was an ideal test track. The new highpressure tunnel cleaner mastered it perfectly. After an extensive trial run, nothing stood in the way of delivery.

We congratulate the new owner on the great new machine and wish you “good business” at all times

Unique – Autonomous tunnel cleaner semi-trailer

We are pleased to present to you the word´s first AUTHENTIC TUNNEL CLEANER-SEMI-TRAILER!

The self-sufficient tunnel cleaner is a TUWA with:

  • 2,000 l of detergent
  • 20,000 l of water
  • 1x pre-wash bar
  • 1x wash bar

AUTARK: With a self-sufficient semi-trailer, the entire system is independet of the towing vehicle. The hydtostatic drive, the entire hydraulic system for all functions and the operator cab are also installed on the trailer. The energy is supplied by a separate motor. A commercially available towing vehicle can be used here, whic can be used for winter service, for example, in winter. This design also has a positive effect on import duties in many countries.

There are 3 variants of tunnel cleaners from Holzmann:

TUWA (washing brushes)

TUWI (sponge)

TUHD (rotating water jet)

Hose inspection

Since hose lines are subject to extreme stress due to external and internal pressure and temperature as well as due to the conveyed medium, these must be regularly checked to minimize risks to humans and the environment.
