Small roller is mainly used in road construction road compaction work small roller plays an important role in modern economy development. Therefore repairing us becomes very important when we want to get rich first. However early in ancient times people began to use pressure equipment to tell everyone.

Earlier in ancient times people used hoof foot to trample rub and compaction to deal with foundation compaction dam and embankment. Before the middle of 19th century western road engineering was mainly crushed stone paving mainly depended on natural rolling of vehicles until 1858 after rolling stone mill was invented promoting gravel pavement development gradually appeared with horse drum compaction work; This is the earliest prototype of roller road, 1860 appeared in France steam roller, further promoted and improved construction technology and quality of gravel pavement, accelerated progress. In 20th century, the world recognized gravel pavement was promoted worldwide, compaction concept gradually became known, roller also appeared on various road construction sites. The middle of 19th century, the invention of internal combustion engine brought enormous vitality to the development of compaction equipment. The first engine driven roller was born early 20th century. Then appeared tire roller, sheep foot roller and light roller almost simultaneously produced, people studied compaction effect of static roller, thought increase roller weight can make roller line pressure increase, thus improve compaction effect. Therefore, during a long period of time, people devoted themselves to developing large tonnage roller, the largest tire roller weighs more than 200 tons, but during this period, the change of roller is mainly reflected in dynamic and shape improvement.
