Pentruder 6-8HF

The Pentruder 6-8HF is a 1-speed wall saw with 15 kW HF-motor. It runs on a smaller and lighter track than the other Pentruder wall saws. Despite it's small size it is a really powerful machine.

The beauty with this machine is that it is very simple and reliable and requires less maintenance than the 2-speed and 4-speed machines.

Reliable 400 Hz technology

  

Pentruder autofeed system

  

Infinitely variable spindle speeds
We have chosen to work with 400 Hz as our base frequency. This gives a very reliable motor, the bearings will live longer and there is no need for frequent maintenance.   Thanks to the exclusive Pentruder autofeed system, the high frequency machinery will always work at maximum power and the cutting will be smooth and uninterrupted.   Infinitely variable spindle speeds in every gear for all HF-wall saws. This is varied electronically with the potentiometer.
 
         
              

Flexible track system

 

Double cooling system for HF-motor

  

Slip clutch protects the HF-motor
Flexible track system saves a lot of time and trouble when setting up the machine.   The double cooling system for the HF-motor gives sustained reliable power and high efficiency.   Main HF-motor has slip clutch for protection of the gear train if a blade is jammed.
         
             

Slip clutch protects the arm rotation transmission

  

Speed reduction gearbox

  

Efficient water supply to blade
The arm rotation transmission is protected by a slip clutch if a blade is jammed.   Oil lubricated speed reduction gearbox with precision ground helical gears.   Efficient water supply to blade central through blade flange, even for flush cutting blades.
         
           

Roller arrangement gives optimal force distribution

  

Low wear rollers

  

Well protected travel and feed motors
The guide rollers on the saw head are aligned above each other, in the same plane as for the cut. This provides the highest levels of safety, stability and precision of cut.   Conical self cleaning low wear rollers for optimal support and control of the saw head.
 		   Travel and feed motors are protected within the chassis body. No electric parts except for connectors are exposed to dirt.
         
 
     
   

     


Highest quality material

    
 		    
 Lightweight saw head built from aircraft quality components machined from solid aluminium.
No castings are used.

Track system

  

Blade guards

  

Transport trolley
The Pentruder 6-8HF runs of a smaller and lighter track than the rest of the wall saws.   The Pentruder 6-8HF is used with "parallel" blade guards.
The guard guide is fixed on the saw head.		   The transport trolley will facilitate transport of the HF-wall saw, power pack and accessories.
