Pengertian Vibro Roller

Kali ini kami membahas tentang pengertian dari Vibro Roller,Vibro Roller adalah suatu alat berat untuk pemadatan yang mengkombinasikan antara tekanan dan getaran, Vibro Roller merupakan pemadatan yang baik dan juga efisiensi, Alat berat ini memungkinkan digunakan secara bebas dalam kegiatan/Aktivitas pekerjaan pemadatan struktur tanah. Karna efek yang ditimbulkan pakan vibro roller merupakan getaran dinamis yang membuat tanah mengisi ke bagian kosong sehingga mengakibatkan tanah menjadi padat dengan kepadatan yang sempurna.
Faktor-faktor tanah yang perlu dilihat dalam proses pemadatan dengan Vibro Roller :
- Frekuensi Vibrator
- Amplitudi Vibrator
- Gaya Sentrifugal

Untuk sistem pendorong,vibra,dan sistem kemudi dioperasikan dengan tekanan hidrostatis agar lebih mudah.

Sejarah Vibro Roller yang di Kutip dari Wikipedia :
"The first road rollers were horse-drawn, and were probably just borrowed farm implements (see roller (agricultural tool)).

Main article: steamroller

Since the effectiveness of a roller depends to a large extent on its weight, self-powered vehicles replaced horse-drawn rollers from the mid-19th century. The first such vehicles were steam rollers. Single-cylinder steam rollers were generally used for base compaction and run with high engine revs in a low gear to promote bounce and vibration from the crankshaft through to the rolls in much the same way as a vibrating roller. The double cylinder or compound steam rollers became popular from around 1910 onwards and were used mainly for the rolling of hot-laid surfaces due to their smoother running engines, however both cylinder types are capable of rolling the finished surface. Steam rollers were often dedicated to a task by their gearing as the slower engines were for base compaction whereas the higher geared models were often referred to as 'chip chasers' which followed behind the hot tar and chipping laying machines. Some road companies in the United States used steamrollers through the 1950s, and in the UK, some remained in commercial service until the early 1970s.

As internal combustion engine technology improved during the 20th century, kerosene-, gasoline- (petrol), and diesel-powered rollers gradually replaced their steam-powered counterparts. The first internal-combustion powered road rollers were very similar to the steam rollers they replaced. They used similar mechanisms to transmit power from the engine to the wheels, typically large, exposed spur gears. Some users did not like them in their infancy, as the engines of the era were typically difficult to start, particularly the kerosene-powered ones.

Virtually all road rollers in commercial use now use diesel power." (sumber https://en.wikipedia.org/wiki/Road_roller)
