For each excavator size the right technology
A Rockwheel cutting unit offers a great number of possible uses – cut a trench faster and more precisely,reduce reinforced concrete bunkers to powder.
Perform contouring and profiling with ease in renovation work – and more quietly than with traditional methods.
We offer cutting units for machines with an operating weight of 1 to 125 tonnes.
The number that comes after the model C (Chain), D(Direct) and G (Gearbox) refers to the average operating weight of the excavator.
A ROCKWHEEL SHOWS WHAT IT CAN DO:
Demolition and concrete work
Cutting performance in the mining sector
Contouring / Profiling /Building renovation
FURTHER APPLICATIONS
• Cutting out tree stumps
• Soil preparation
• Underwater cutting
• Tunnelling
• Road construction
THE BENEFITS
There are many good reasons for using a Rockwheel cutting unit:
• Produce an extremely accurate profile in excavation and tunnelling work or in surface preparation.
• Reuse the finely grained excavated material for backfilling.
• Fewer vibrations reduce fatigue when working.
• Reduce the risk of damage in and around the site.
• Use the cutting units in noisesensitive zones, as they are relatively quiet to operate.
