“The fact that the Pentruder 3P8 wire saw could be fitted directly on the concrete foundation, to make a “direct cut”, saved us a lot of time and trouble when setting up the machine. In contrast to our bigger machine the lightweight modules can be mounted directly to the surface being cut. Together these features made the setup quick and convenient”, says Anders Jäderholm, partner of Betongborrar’n. “
The foundation that was cut down was approximately 2 meters (3’) wide and 8 meters (26’) long. The pieces were then cut in several 2 meter long by 1.5 meter (5’) wide by 2.5 meter high blocks. This was the biggest size which could conveniently be transported away from the jobsite.
The bottom cut was 2 x 8 meters, (6.5’ x 26’), for a total area of 16 m2 (172 sq.ft). This cut took 3.5 hours including some problems with loose material which jammed the wire. For the whole job, the performance was never below 4.5 m2/hour (48 sq.ft./hour). Typically 5 m2/hour (54 sq.ft./hour) and upwards was achieved when conditions were best.
The cutting went very well and the contractor especially appreciated the big wire magazine and the smooth operating automatic feed control. “This is what it should be like”, comments Anders Jäderholm. “It’s so easy to operate, and we have never seen a wire saw that can start the wire like this. We didn’t even chamfer the corners. With the other saw, it would require several additional satellite pulleys, and a lot more time to complete the setup. Another big plus with the Pentruder 3P8 is the fact that the feed control is entirely electric and there is no need for an air compressor. For us this is especially important in the wintertime in damp and cold conditions.”
