KINSHOFER is introducing the WS Drum Cutter Series. The drum cutters feature an exclusive pick angle and optimal chisel arrangement for high performance and minimal wear, suiting tunnelling, road construction and demolition.
Drum cutters are an alternative to hydraulic breakers and the WS-Series are one of the quietest in the industry, suiting them for use in areas with noise restrictions. They also produce less vibration than breakers, so contractors can use them where there is a risk of disturbing a nearby structure’s foundation.
KINSHOFER is said to achieve the low noise output and low vibration attachments through the use of a high-torque hydraulic motor. The motor powers the drum cutter while its gear reduction optimises torque and cutting force. The higher torque enables the attachment to achieve greater cutting efficiency while operating at a slower speed than competitive drum cutters. The controlled speed of the attachment reduces noise and vibration as well as maximising operator comfort. Additionally, the hydraulic motor is adjustable to match the output of an excavator’s hydraulics.
KINSHOFER has a drum to match any application. The rock drum effectively breaks soft to medium-hard rock with its strategic chisel pattern while the profiling drum’s higher density of chisels shapes and levels soft to medium-hard rock in tunneling applications. The demolition drum offers reduced vibrations due to a wear-protected spiral sheet and is ideal for cutting medium-hard to hard rock as well as concrete.
Based on the application, KINSHOFER offers four chisel tips that attach to the wear pick: standard, heavy-duty, wear-protected and wood. Standard chisels are excellent for breaking asphalt, argillite and other soft to medium-hard rocks while the heavy-duty chisels power through medium-hard to very-hard materials such as limestone and concrete. Wear-protected chisels are ideal for abrasive rocks such as sandstone. The wood chisel is designed specifically for wood applications, such as stump removal. Wear picks can be replaced in minutes.
The attachment’s heavy-duty sealing system enables underwater to depths of 25m for applications such as bridge repair. WS-Series Drum Cutters are available in seven models for 2- 60tonne excavators.
