The kelly bar monitoring application deals with cycling activity that repeats basic movements – bat not exactly.

The requirement is to keep measuring accuracy along the process, and, at the same time, to submit the operator with selected, relevant, information.

TomTech III deals with the challenge by intensive use of the Wise Sensor and Soft Device abilities.

The sensor’s built in micro-processor takes care for the preciseness, applying special software package.
at the some time, the main computer monitors the activities using audio-visual means.

The result is guidance at the level of instrumentation drilling – the operator does not have to look outside the cabin, he has all he needs monitored by TomTech III, applying visual images and audio signals.

A good example for the power and Efficiency of the Visual-Audio capability is the way TomTech III instructs the operator to swing back to the pile center, after unloading the ground from the bucket.

As long as the turret angle is more then 5 degrees, there is no audio signal. Once the angle is less then 5 degrees – audio sound, from the deviation side of the swing angle, starts. The sound lasts until the turret aims the center of the pile. If there is over shooting, and the turret rotated too much, a sound from the other side starts.

Thus, just utilizing the audio signals, the operator may fully control the swing motion of the rig, with no need to look outside the cabin, nor to trace the monitor.

The measurements are accurate and smart. The accuracy enables the operator to relay on TomTech III, and to perform a pile which is as closed to theoretical cylinder as possible. The smart features solve unexpected problems like cave-in, movements of the rig, and mechanical break downs.

The main advantages of the kelly bar application are:

• Reduction of over concrete consumption.
• Productivity increasing.
• Down time reduction.
• Longer cable and kelly bar life time.
• Operator performance upgrading.
• Parameters registering.
