Operators Manual - High Frequency driven Pentruder 3P8 Wire Saw 

Pentruder - Stronger than ever!  Applying Standards That Are Years Ahead Of the Competition.  

Tractive AB  28 January 2009    Page 4 

Strong features of the 3P8 wire saw, continued 

 

•

  The cutting speed is continuously variable from 0 to 22 m/second, 4330 sft/min, when 

driven by the 18, (25HP) and 22 kW (30HP) motors, and up to 25m/s, 4920 sft/min.  for 
the 27 kW (37HP) motor. 

 

•

  The wire magazine stores 8 m of wire per 1 m of stroke of the tensioning carriage (the 

upper carriage). The magazine can store (pull in) over 20 m of wire if the total column 
length is 3.0 m or more. A combination of 0.5, 1.2, 1.5 and 2.0 m columns ca be used. 

 

•

  The wire can be run over all wheels on the machine without opening the wire. 

 

•

  A patent pending system allows the wire to be run also over the adjustable swivelling 

wheels, without having to cut the wire. 

 

•

  All swivelling wheel assemblies can easily be removed from their holders for easy 

cleaning and maintenance, by just removing one screw. 

 

•

  Fully enclosing guards protects the operator(s) and keeps all expensive parts 

(reasonably) clean, like the carriages, main pulley drive system, column, etc. 

 

•

  All pulleys can easily be removed from their mountings. All bearings are sealed with 

external seals. 
 

•

  The main drive pulley is driven by a Gates toothed high torque Carbon cog belt. The 

belt transmission is hidden behind guards and protected from concrete slurry. The belt 
can be replaced using only a set of standard 6, 8 and 14 mm Allen keys. 

 

•

  The magazine and idler wheels are Ø 198 mm O.D., 7,8” and the wire is running on 

"pitch" Ø 180, 7.1”. 

 

•

  The magazine and idler wheels have a rubber rings with a specially designed type of 

rubber compund giving very good wear resistance. There are totally eleven such 
wheels on the 3P8, including six wheels in the magazine. 

 

•

  All pulleys are a two piece design, and are bolted together. All rubber liners (rings) can 

easily be replaced using standard tools. 

 

•

  When the rubber liners / rings are new, the groove width for the wire, in all wheels, is 

10 mm, 0,3930”, meaning that it's suitable for a Ø 11 mm, 7/16” wire. Ø 8 mm, 5/16” 
wire also works well.
