Jetframe 101 Nalta

The world’s smallest hydrodemolition robot, replacing your hand lance or operating underwater
101_image The Conjet Jetframe 101 Nalta has been designed to replace hand lances for a large number of hydrodemolition applications, increasing productivity and improving safety for operators. The compact and lightweight Jetframe 101 Nalta is supplied with high pressure water from a standard hand lance pump and can operate on flat as well as curved surfaces with a radius as small as 400mm. It consists of a feed beam with an oscillating lance, hydraulic unit and a radio remote control box. 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 suitable safe distance
  • Increased production rate
  • No rest needed between sessions
  • Can work with higher reaction forces
  • One-man operation

Special applications

Since the Nalta climbs on standard scaffolding pipes, the applications are endless. Whether the work area is flat or round, wide or narrow, the bearing frame can be adapted to suit the environment. Examples of special applications for the Nalta are shown to the right. Is your project too complex for ordinary hydrodemolition robots? Ask Conjet about adapting the Nalta to match your needs!


  • Underwater operation
  • Operation on curved pillars down to a radius of 400mm
  • The feed beam can be extended to 3m using extra sections
  • The robot can climb on standard scaffolding pipes
  • A trolley makes the Nalta’s hydraulic unit easy to transport
  • Highly versatile
  • Can access areas unavailable to other hydrodemolition robots due to its minute size
