History
Small roller first appeared in Britain in the 1980s, a company called Pi Feite machinery factory developed, produced first small hand roller. It is very simple structure, inconvenient operation. 1990s, China introduced imported the production technology, coupled with a completely developed tandem roller compactor and type of with cab. Function 1、Easy to operate small roller, since the entire machine itself is relatively lightweight, so the operation is very convenient, as long as the operator with relevant knowledge can control it, so called "fool advantages. 2、To get a small roller compaction density, the choice is tire roller. Tire roller will not damaging the soil original viscosity during rolling , good binding properties between the layers of soil, combined with the front wheels can swing it more uniform compaction, there will be no false compaction. Work performance Roller is a rolling plain for heavy machinery and equipment, it works primarily with its own gravity to those sandy, semi-clay soil of concrete or asphalt pavement plastic to strengthen the role of compaction. It is common for a higher level of traffic engineering requirements, such as highways, railways, bridges basis. Easy to operate small roller volume is small, compact, easy to transport,work strength , high efficiency. And supporting use with the large rollers. With the development of urban construction, small roller used more widely, which also contributed to the development of easy to operate small roller manufacturers. Two-chamber of easy to operate small roller hydraulic cylinder communicates with the oil tubing. Small roller hydraulic cylinder , to the two chambers simultaneously through the high-pressure oil, at the same time as the two chambers pass into the high-pressure oil, but vary the effective area of the two chambers, so that the force generated ranging rod chamber there are more than traction rod chamber, push the piston moves to the right, right-drained fluid chamber and into the left chamber of the cylinder, thus increasing the flow of the left chamber, accelerated to the right movement.
