WS-Series drum cutters are available with three drum types, a profiling drum for tunneling, a rock drum for quarry and mine applications, and a demolition drum for cutting concrete.
Kinshofer, a global manufacturer of excavator and loader crane attachments, introduces the WS drum cutter series. Kinshofer acquired the drum cutter line in early 2018 with the purchase of Schaeff Transverse Cutter from Atlas GmbH. The drum cutters feature an exclusive pick angle and optimal chisel arrangement for high performance and minimal wear, making the attachments ideal for mining, tunneling, road construction and demolition.
“Years of engineering and manufacturing have shaped the WS-Series drum cutters into precise rock breaking units that maximize efficiency and outperform the competition,” said Francois Martin, Kinshofer North America general manager. “Our team of application specialists work with contractors to choose the best drum and chisel for their specific application, minimizing noise and vibration while optimizing performance.”
A Quieter Alternative
Drum cutters are a quieter alternative to hydraulic breakers and the WS-Series are one of the quietest in the industry, according to the manufacturer, making them excellent for use in areas with noise restrictions. They also produce less vibration than breakers, so contractors can use them where there's a risk of disturbing a nearby structure's foundation.
Kinshofer achieves the low decibel output and minimal vibrations of the attachments through a high-torque hydraulic motor. The motor powers the drum cutter while its gear reduction optimizes 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 maximizes 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 in mines and quarries 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 and furnace gravel. The wood chisel is designed specifically for wood applications, such as stump removal. Wear picks can be replaced in minutes, leading to greater productivity and less downtime.
Selecting the proper chisel and drum combination is key to optimizing performance and reducing attachment wear. Kinshofer's application specialists work closely with customers to understand applications and material conditions so they can recommend the best drum and chisel tip for each situation.
The attachment's heavy-duty sealing system enables underwater operation as deep as 25 meters for applications such as bridge repair.
WS-Series drum cutters are available in seven models for 2- to 60-ton excavators. For added versatility the attachment can be paired with Kinshofer's NOX tiltrotator, which enables 360-degree continuous rotation and multi-directional tilting up to 55 degrees.
Founded in Germany in 1971, the Kinshofer Group includes the KINSHOFER, Demarec, RF Systems, Auger Torque, Doherty and Solesbee's brands. Kinshofer offers a wide product range with just about every type of attachment for equipment carriers with and without hydraulics in industries as diverse as scrap, demolition, railway, landscaping, construction, snow clearing, excavating, road building, forestry, tire recycling and biomass.
