Hilti has recently launched a rotating laser tool which enables a single person to perform a variety of levelling and aligning tasks with great precision

A Robust rotating laser that levels itself automatically within seconds is the latest development from the laser laboratory of Hilti, a global construction tools and fastening specialist

"Every bit as robust as it looks, the sturdy new Hilti PR 20 can take the tough conditions of outdoor work on construction sites. This highly accurate tool for levelling and aligning in the horizontal or inclined planes provides dependable results in virtually every situation over an area 400 m in diameter," says a spokesman for Hilti Regional Office

"PR 20 simply gets the job done more quickly and more efficiently - and all that with just a touch of a button," he continues. "Once set up and levelled, it can be relied upon to provide accurate references. Its built-in shock-warning system alerts the user immediately in the event of heavy vibration or movement, thus actively preventing errors that can be caused by continuing work when out of level." "The rotating laser is built on revolutionary technology that can replace almost every optical levelling tool. The PR 20 is the perfect replacement for optical levelling tools, which usually require two people to operate, thus saving costs," he adds

The system comprises the PRA 20 laser detector, featuring an extra-long detection window, which locates the rotating laser beam quickly and easily, under all lighting conditions. ...
