They are easier to control and afford premium precision when working with sensitive structures. This makes them a great option for projects such as foundations and bridge abutments.

Cutterheads operate with low-noise and smoothness that result in stable, consistent walls that are not susceptible to micro-cracks and over-breaking.

These benefits are the primary reasons that project managers opt for cutter heads when they know that precision is a high priority.

No other tool on the market offers the level of control that a transverse cutter head can provide.

If you have decided that a cutter head is the right tool for your next project, here are four tips that will improve efficiency when scaling concrete structures.

Correct Flow

It is essential to have correct flow and pressure set up on the excavator, backhoe, or skid steer loader before using the cutterhead.

The correct setting is crucial to the cutterhead performing at its full potential.

If the machine is underpowered it will result in slower rotations-per-minute (RPM) and potentially low stall pressure. If the machine is overpowered it will greatly accelerate motor fatigue and potentially result in failure.

Vigilant Maintenance

When working with concrete and other hard materials it is important to constantly monitor the tips of the cutter bits or picks to make sure they are in good working condition.

Depending on how abrasive the material is will determine how long a pick can operate.

Working with a worn out pick will inhibit productivity and could create more significant damage to the equipment.

Prevent unnecessary down time by paying attention to when picks are wearing out and anticipating when they will need to be replaced.

Depth Guides

One measure that is implemented in certain concrete scaling projects is a depth guide.

Depth guides are custom made and allow precision cutting by limiting the depth the cutting drums can get into the material.

Simply pick the maximum depth that you want the cutting drum to reach to, and the depth guide can be made to that specification.

Depth guides are only necessary if precision is absolutely critical, but if you have a project where you are worried about cutting too deeply into the material, a depth guide is a great solution to remove that possibility.

Sufficient Working Space

Excavating equipment is large and needs direct access to the structure.

To work as efficiently as possible, organize the working space so that it is large enough to accommodate the excavator and it has room to engage the surface from a direct angle.

By engaging the surface from a direct angle, you can ensure the contact is flush with the wall and your operator has optimal precision in the cutter heads movements.

If you are looking for areas in your scaling projects that could improve in efficiency, these four steps will help you take positive steps in that direction.
