There's nothing to be surprised about.! It's very different from the environment in North America where there are many detached houses. This place is familiar with the urban environment. The pros and cons are clear!The water pipe that you see in the video is a water pipe for some houses.Large commercial houses or multi-family houses have large pipes installed independently. Do you operate the same excavator as me? Thank you for leaving a comment.

​@@excavatorlaboratory I don't operate excavators. I've always been curious about construction. Rototilt excavator heads are rather rare in North America. I live in Canada, so we need to burry our pipes under the frost line which is at least 5 feet deep. Most construction compagnies don't bother with trench boxes and choose to just slope the hole which makes for quite a large trench. To get that amount of work done in a reasonable amount of time takes a bigger machine. The machine that you are driving is just too small for most construction jobs, and too big for most landscaping jobs that you would find where I live.

현재까지는 괜찮네요. 구리스를 신경써서 자주 주고 있습니다. 저보다 한달 늦게 구입한 차량은 유격이 있었는데,.. 구리스 생각보다 자주 주셔야 합니다. 그리고 회링 주변부에 구리스때문에 많이 지져분 합니다. 작업전 매일 아침 구리스 주입하고, 항상 구리스를 딱아네고 작업합니다.

@@excavatorlaboratory 네 감사합니다 ^^ 구리스 자주자주 줘야겠네요
