The new Hilti DS TS20-E Electric Wall Saw features high-frequency motor technology and HTC intelligent control to achieve top cutting performances. High-frequency electric drives on wall saws like the DS TS20-E are now becoming established in this class and succeeding conventional hydraulic systems. The DS TS20-E, designed for use by concrete drilling and sawing service contractors, sets a standard for saws in the medium performance class for cutting to depths of up to 21 in.
The DS TS20 sets the pace in a wide range of sawing applications in the medium- to heavy-duty range. Hilti Traction Control, the innovative electronic saw advance control system, ensures maximum sawing performance by making full use of the electric power available. Critical drive parameters are monitored and measured continuously, while an ingenious digital control system calculates the optimum saw head advance speed. HTC’s sensitivity and efficiency become particularly obvious when the blade runs into reinforcing bars in the concrete. Blade jamming or even complete stalling of the saw can be avoided to a great extent. This highly efficient saw advance control system not only boosts cutting performance, tests have shown that it also extends saw blade life.
Compact saw head with high frequency motors
Use of high-frequency motor technology has made it possible to develop a compact, mid-range electric wall saw with an outstanding power-to-weight ratio. When powered by a 32 A supply, the DS TS20-E provides an output of 15 kW (S1, continuous operation) and, thanks to its advanced electronic control system, maintains a constant torque with all blade diameters — 24 to 48 in — without need for mechanical gears. Blade speed is infinitely variable and can thus be adjusted exactly to suit the blade diameter used and the type of material being cut. This saw’s innovative high-frequency drive with HTC control offers a level of performance previously attainable only with hydraulically-powered systems running on a 63 A electric supply.
