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 400 mm. It is mainly used for the hydrodemolition of concrete, but is also suitable for other applications, such as surface reparation and descaling of steel.
The Jetframe system NALTA consists of a feed beam with an oscillating lance, hydraulic unit and a remote control box. The oscillating lance, fixed to the cradle, travels along the 1m long feed beam, which can also be extended with two extra sections to a maximum length of 3m. The cradle moves, oscillating the lance between two manually set turning points on the feed beam. At each turning point, the lance angle of attack inverts. This function is mechanically automated which enables the unit to operate under water. The Conjet research team has come up with a patented solution which allows four hydraulic hoses to control all functions of Jetframe 101 NALTA, including cradle movement, lance oscillation and angle as well as feed beam indexing step units.
The feed beam is attached at each end to a patented hydraulically controlled step unit. The two step units, fixed onto standard scaffold tubes (48.3 mm), automatically climb up and down after each pass of the cradle (cutting head). The step units can also operate on scaffold tubes bent to a diameter of 800 mm or more, making the versatile Jetframe 101 NALTA ideal for working on curved as well as flat surfaces.
Radio control for NALTA
The Jetframe 101 NALTA system is powered by a hydraulic unit that operates on a single phase 230V, 10A supply. It is mounted on a trolley for easy transport. The operator controls all movements of the Jetframe 101 NALTA from a hand held portable control box.
Jetframe 101 NALTA is prepared for radio control.
Optional rotor head for surface preparation
Rotor for NALTA
A rotor head is available as an option that can be used for numerous surface preparation tasks. If steel surfaces are blasted with water with a pressure exceeding 2500 bar grade HB 2 ½ grade can be achieved.
At Conjet, safety is paramount
Anything can happen on a worksite! We are well aware of this after years and years of experience. That is one of the reasons for our safety thinking and features on the NALTA. Should the operator be unable to reactivate the automatic operation within the given time interval, automatic operation interrupts which in turn brings the high pressure pump to an idle at no pressure.
