Automated Demolition
Jetframe 101 Nalta – Efficient and portable.

Nalta allows selective concrete removal in narrow confined areas and is specifically designed to operate where space is limited, such as between a building or scaffolding.

Nalta can operate on horizontal, vertical and angled surfaces, including ceilings and underneath bridge decks. It can operate on flat as well as curved surfaces with a radius as small as 400mm.

The Nalta is mainly used for the hydrodemolition of concrete, but is also suitable for other applications, such as surface preparation and descaling of steel.

Advantages compared to handlances:

  • Operation is done from a safe distance
  • Increased production rate
  • No rest needed between sessions
  • Works with higher reaction forces
  • Operates underwater

CCTV inspections
Kelly’s Australia use the very latest technology to provide detailed inspections of a drain or pipe system below ground or above ground in areas not readily accessible.
