Used Rollers for Sale at Fenton Plant Machinery

Fenton Plant Machinery have used rollers for sale

We have used rollers for sale at Fenton Plant Machinery. Road rollers use the weight of the vehicle to compress the surface being rolled. Initial compaction of the substrate on a road project is done using a padfoot drum roller, which achieves higher compaction density due to the pads having less surface area. Rollers are used predominantly for road resurfacing, groundworks etc.

So what is a Roller?

A road roller (sometimes called a roller-compactor, or just roller) is a compactor-type engineering vehicle used to compact soil, gravel, concrete, or asphalt in the construction of roads and foundations. Similar rollers are used also at landfills or in agriculture. Other variations of roller include vibrating roller, double drum roller, walk behind roller and pedestrian roller.

There are many variations of uses for the modern roller, here’s some of them

[1] On some machines, the drums may be filled with water on site to achieve the desired weight. When empty, the lighter machine is easier and cheaper to transport between work sites. On pneumatic tyre rollers the body may be ballasted with water or sand, or for extra compaction wet sand is used. Modern tyre rollers may be filled with steel ballast, which gives a more even balance for better compaction.

[2] Additional compaction may be achieved by vibrating the roller drums, allowing a small, light machine to perform as well as a much heavier one. Vibration is typically produced by a free-spinning hydrostatic motor inside the drum to whose shaft an eccentric weight has been attached. Some rollers have a second weight that can be rotated relative to the main weight, to adjust the vibration amplitude and thus the compacting force.

[3] Water lubrication may be provided to the drum surface from on-board “sprinkler tanks” to prevent hot asphalt sticking to the drum.

[4] Hydraulic transmissions permit greater design flexibility. While early examples used direct mechanical drives, hydraulics reduce the number of moving parts exposed to contamination and allows the drum to be driven, providing extra traction on inclines.

[5] Human-propelled rollers may only have a single roller drum.

[6] Self-propelled rollers may have two drums, mounted one in front of the other (format known as “duplex”), or three rolls, or just one, with the back rollers replaced with treaded pneumatic tyres for increased traction.
