Cutter Heads, Earthmoving Attachments

Unrivalled performance: Simex Cutter Heads

Make an impact with Simex cutter heads designed to suit a range of earthmoving applications.

Operators are increasingly turning to high performance earthmoving attachments like cutter heads that help cut through the toughest surfaces with little fuss.

When conventional excavation systems are too weak and percussion tools have little impact, Simex cutter heads (also known as drum cutters) are the ideal solution for the most complex applications.

The versatile Simex cutter heads are designed to suit a range of applications, from trenching in the road sector, passing through the vertical profiling of concrete or rock walls in construction and infrastructure, up to the toughest quarrying or tunnelling work.

In comparison to traditional rock grinding methods, such as explosives or hydraulic rockbreakers, the Simex cutter head range offers a number of unique advantages, which make them the attachment of choice for hard surfaces – more accurate profiling and precise cuts, versatility in narrow and deep excavations, continuous operation and greater efficiency, and minimisation of fractures within the rock mass.

The Simex range is renowned for its work in finishing operations where high precision, minimum disturbance and aesthetic results are required.

Their quiet operation and low vibration emission (<87 dB) make them ideal when working near sensitive areas such as residential zones, hospitals, schools, bridges, and other existing infrastructure.

Simex cutter heads are available in a range of models to suit 2.5 to 75 tonne excavators. The cutter heads can be used to cut through varied degrees of rock hardness of up to 85 MPa.

Unrivalled performance

Featuring patented technology, the direct drive high displacement hydraulic piston motor offers high torque and high performance, enabling operators to consistently bore through the toughest materials without losing power.

The direct drive motor does not require lubrication or other routine maintenance. A filter on the feed and drainage line are both integrated, protecting the hydraulic system from any external impurities, which can damage or reduce the performance of both the excavator and the equipment.

Additional protection from pressure peaks is provided on drainage line by an accumulator and a fuse, and on feed line by a flow-limiting valve. The latter also allows easy coupling with various excavator models and sizes, facilitating installation and calibration operations.

With replaceable anti-wear plates, and mechanical gaskets fitted on the drums, the equipment will also be safeguarded from dust, allowing the rotary cutters to work completely submerged either in the ground, or in water up to a maximum depth of 30m.

The frame’s unique shape reduces the distance between the drums and improves the total working width. Furthermore, milled material is discharged from the trench without getting stuck in the structure due to the symmetry of the frame, which also allows hoses to be hooked up at sides and front.

The cutter heads can be rotated 90 degrees thanks to square holes in the coupling plate, which makes the equipment even more productive and versatile when it comes to different applications.

Estimate your hourly production with the new Simex calculator

The team of experts at the Simex factory in Italy has launched a new tool that calculates the theoretical hourly production if using Simex high performance rotary cutter heads. The calculator will recommend the most suitable model based on the material you need to work with.
