Hello, everyone.

This is Enta.

The photo above was taken from the operator's seat of a crawler-type rotary percussion drill.

This is a photo of me drilling a hole, but you can't tell at all where my hands are or what I'm doing, lol.

Although the control panel can be lowered to the side, depending on the situation on site, it may be better to operate it while seated on top of it.

You don't really see crawler-type rotary percussion crushers very often.

I have almost no idea what’s going on around me or what people nearby are doing, or even where they are.

Well, the crawler doesn't move while drilling, but in the past, it was a common accident for workers to get their hands caught if they didn't receive a signal while working nearby.

Nowadays, strict adherence to traffic signals has become the norm, and accidents are rare.

A 20-year-old at our site is teaching construction techniques at a second job site.

First, the signal, right?

"Give a signal before you do anything," he said.

Since we’ve explained that the machine won’t move unless it receives a signal, they make sure to send the signal properly.

They also mentioned that the pace of the work depends on my hand signals and movements, and they’re really doing their best.

If you make it a strict rule that the machine won’t start until a signal is given, they will always give you a signal.

Once we’re on the same page, I think a glance will be enough, but at first, we’ll need a signal.

This is the only way to go.

I want you to learn the importance of signals while you're still young.

Now it's just a matter of theory.

Why do we use hand signals or point-and-call? And why is the cement slurry mixed in this particular ratio?

We're currently training professionals in slope stabilization while explaining things like quality and finished appearance, lol.

In the beginning, basic signals are important, so use them to ensure clear communication with your partner.

Signals can help you protect your own life and prevent the other person from being careless.

Let's communicate with each other and work safely!

See you later
