| Automatic Feeding System |
ＥＨＡＣ-130Ａi |
|
|
| ■ Automatic Feeding System for core drill. Professional technique is installed
in CPU. |
 |
| ■ Easy to attach CONSEC drill carriage. |
| ■ Integrated reinforced steel sensor function.It enables not to cut reinforcing
steel in case of small diameter drilling targeting earthquake strengthening.After
detecting reinforcing steel, core drill automatically stops using built-in
“Reinforcing steel detection software” |
| ■ 16 steps of drill load settingLoad setting is possible up to 16A depend on core drill and working situation. |
| ■ Automatic stop function After complete drilling, feeding and drilling
automatically stop. |
| ■ 2 feeding speeds make it possible to drill small diameter to big diameter. |
| ■ Reverse function.After completing drilling, push the Auto Feed button,
drill motor comes up for maximum 5 minutes. |
| ■ CE Marking and RoHS regulation are certified. |

| Reinforcing steel sensor function |
■ Principle of reinforcing steel sensor function
It needs a practice to detect the reinforcing steel in a concrete by hand feeling.
In case of drilling through hole from 1m to 2m, the reinforcing steel at core drill side can be detected by Reinforcing Steel Scanning Machine. So we don’t need to care about cutting of the reinforcing steel. However there is a possibility to cut reinforcing steel which is not detected reinforcing steel by Reinforcing Steel Scanning Machine and backside of material.
So we developed “Reinforcing Steel Detection Software” to prevent from cutting reinforcing steel by mistake.
“Reinforcing Steel Detection Software” is always monitoring drilling speed of core bit in order to judge whether the reinforcing steel exist or not in a concrete. If the reinforcing steel is grinded during drilling, the software makes Core Drill stop instantly. So reinforcing steel isn’t cut.
