70 mm column system as rig
High starting torque makes it easy to start the wire over sharp corners and irregularly shaped objects. Normally corners do not have to be chamfered before the wire is started.
Easy Setup
The wire can be run over all wheels on the machine without opening the wire. The wire can be run also over the adjustable swivelling wheels, without having to cut the wire. The 3P8’s design allows for direct cuts to be made, and satellite wheels can mostly be omitted.
Big storage capacity
Wire storage capacity without external pulley, approximately 16 m. Two 1.2 m columns = approximately 1.4 m of travel = 11.2 m storage.
Easy start of the wire
The high starting torque makes it easy to start the wire over sharp corners and irregularly shaped objects. Normally corners do not have to be chamfered before the wire is started. On the 3P8, the wire can be started and reversed several times to simplify start-up. A groove can be cut also on the slack side before starting to cut.
Automatic feed and wire tensioning
Automatic feed, without air cylinders or need for compressed air. Wire tensioning is fully automatic, with some exceptions. The tensioning of the wire is governed by software and a microprocessor / digital servo amplifier driven electric feed motor.
Continuously variable cutting speed
The cutting speed is continuously variable from 0 to 21 m/second (4100 sft/min), when driven by the 18, (25HP), 22 kW (30HP) or the 27 kW (37HP) motor.
Exceptional cutting results
Normal results in concrete, using a wire that is well adapted to the high power of the 3P8 wire saw are between 3 – 6 m² 32 – 64 sq ft per hour in reinforced concrete containing “normal” aggregate and between 1.5 – 3 m², 16 – 32 sq ft per hour in reinforced concrete containing flint or river gravel aggregate.
Robust connectors
The connector housings are made in-house from high strength aluminium. At service the connector inserts can be replaced with hand tools.
High power and reliability
The Pentruder wall saws are powered by very powerful HF-motors. They all have very efficient cooling, high torque and are built by the best materials for reliability and a long lifetime. Reliable 400 Hz technology ensures a very reliable motor, long life of the bearings and no need for frequent maintenance.
Slip clutch protects your machine
he HF-rotor to destroy the gears in the transmission. The rotor inertia will want to keep on turning the rotor, and to stop the rotor from 13.000 rpm to a dead stop in a fraction of a second is just not possible. The speed of the rotor must be reduced gradually and this is taken care of by the slip clutch.
