How to choose the correct size rock cutter for my excavator?
What production rate can I expect from a drum cutter?
The Productivity Table in the downloads below can be used as an indicator of the productivity rates that can be achieved within the operating range of rock hardness suitable for rotary drum cutters. These levels can vary by as much as plus/minus 15% depending on:
- size of hydraulic motor
- cutting direction (wall, floor, trench, etc)
- operator experience
- ground conditions e.g. layers, fissures, weathering, etc
