Pentruder 3P8 hydraulic wire saw

The Pentruder 3P8 wire saw is the result of all our efforts to create the best and most efficient wire saw on the market. It combines low weight with extraordinary performance and is suitable for both small and very big jobs.

The set up is quick and mostly a direct cut without extra satellite pulleys is possible. The start of the wire is very easy thanks to the high torque already from start. 

The storage capacity is more than 20 meters depending on what combination of columns is used.

Pentruder 3P8 hydraulic wire saw can be run by  Pentpak 25 and 34 cc hydraulic motor or by the Pentpak 15 and 20 and 16 or 25 cc hydraulic motor, see System.

Modular build up - Easy transport

 

Big storage capacity

 

Very strong

The 3P8 is built up by easy to handle modules which are fitted on an extendable drilling machine column, which in turn is fitted on a base plate. All modules weigh less than 25 kg. Quick disconnect couplings make the assembly of the modules quick and easy.   In its standard version, the 3P8 can pull in 16 m of wire out of the material being cut. With an extra idler / slack tensioning wheel, the machine can take up 20 m wire.
 
  The hydraulic 34, 25 and 16 cc hydraulic motors gives a lot of power to the wire. 
 
         
              

Optimal force transmission

 

Easy start of wire

 

Automatic feed and wire tensioning

The main drive pulley has a diameter of Ø 500 mm, 20”. It has a rubber drive ring with a specially designed type of rubber compound giving very good traction wire to rubber, even when wet. The wire wraps around the main drive pulley over 270°, which gives superb traction.   The high starting torque makes it easy to start the wire over sharp corners and irregularly shaped objects. 

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, without air cylinders or need for compressed air. The hydraulic feed regulation makes it easy to run the wire saw and extends the lifetime of the wire. 
         
                

Easy setup

 

Clever design of wheels

 

Long life of pulley rubber liner

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.
 
  All wheels can easily be removed from their mountings. All bearings are sealed with external seals. The wheels are a two piece design, and are bolted together. All rubber liners (rings) can easily be replaced using standard tools.   The 3P8 drive pulley rubber liner wears out after about 400 - 500 m2.

Some of the rubber liners on the smaller wheels will wear out after approximately 100 m2 (depending on conditions), under full load with a 22 kW motor.

Rubber liners are relatively cheap and easy to exchange.
         
         

Practical and safe guards

 

Easy cleaning and maintenance

 

Longer wire life

Fully enclosing guards protects the operator(s) and keeps all expensive parts (reasonably) clean, like the carriages, main pulley drive system, column, etc.
 
  All swivelling wheel assemblies can easily be removed from their holders for easy cleaning and maintenance, by just removing one screw.
 
  Thanks to the smooth run with 3P8 automatic hydraulic feed the wire has a longer lifetime than with many other wire saws.

Pentruder MCCS is a truly modular system based on the wall saw track. The track is used both for the wire saw rig and for the drill rig, as well as for other more special set ups.

The wire saw rig can also be built with the 70 mm column system which is also suitable for core drilling.
