Description of the machine
The Pentruder 8-20HF / 8-20iQ represents a very
modern and safe type of concrete wall saw. The
Pentruder 8-20HF /8-20iQ is developed and
manufactured by Tractive AB in Sweden in a
process where safety awareness, performance
and reliability were the most important design
parameters.
By taking advantage of experience and know-how
built up over many years in this specialised field,
this new design can offer the user great
advantages, for example the markets best
performance to weight ratio.
The Pentruder 8-20HF /8-20iQ offers out-standing quality. It is the culmination of exacting goals for
quality and safety set at every stage from concept
to finished product.
Saw head Pentruder 8-20HF / 8-20iQ
The Pentruder 8-20HF / 8-20iQ is the most efficient machine for concrete cutting available on the
market today. The design offers many features to make your work safer, easier and more efficient.
Low weight, only 24 kg (54 lbs) for the saw head less motor, and 15,5 kg (34 lbs.) for the 22
kW motor. The machine is ideal for cutting with blades from Ø 800 (32”) to 2000 mm (78”)
diameter.
Lightweight saw head built from aircraft quality components machined from high tensile
strength billet aluminium. No castings are used.
Quick release coupling for the HF-motor on the saw head. To put the motor on the saw head
or to remove it takes just a few seconds.
Quick release mechanism of saw head to and from track. Eccentric rollers on the saw head
allow it to be fitted and removed from the track with ease.
Superior blade mounting system by patented quick release coupling.
Conical self cleaning track rollers offers optimum control of the saw head along the track.
The rollers are easily adjustable and offer reliable operation over a long period of time. The
guide rollers are arranged in the same plane as the saw blade for optimal force distribution.
Oil lubricated speed reduction gearbox in the HF-motor with precision ground helical gears.
For optimum accessibility the saw arm can be rotated through 360 degrees in either
direction.
The saw head accepts a 1000 mm (40”) saw blade free from the wall.
Double motor cooling system, i.e. both rotor and stator are cooled, for sustained reliable
power and high efficiency.
Warning! The guard must be fitted whenever
the machine is run.

Efficient water supply to blade central through blade flange, even for flush cutting blades.
Travel and feed motors are protected within the chassis body. No electric parts except for
connectors are exposed.
Travel and feed transmission is by means of planetary gear transmission and a self blocking
worm gear transmission. No risk for unexpected movements of the saw head as a result of a
failed electric motor brake.
The worm screws are supported by oil lubricated axial needle roller bearings and axial thrust
ball bearings.
The HF-motor has a long life multi plate slip clutch for protection of the gear train if a blade is
jammed. The slip clutch can easily be removed and serviced, or replaced if needed.
The arm rotation transmission is protected by a multi plate slip clutch if a blade is jammed.
The operator can just “move back” from the cut and start again. Also this slip clutch can
easily be removed and serviced if needed.
The lower pair of conical rollers are fitted on adjustable eccentric shafts.
