Walk behind rollers come in two basic types. Single drum and double drum. The right one depends on what you compact most, soil or asphalt, and how tight your work sites are. This guide lays out the difference for South India contractors. For the full range, see our road rollers.
What the Two Types Are
A double drum roller has a steel drum at the front and the back. Both drums compact, so you get pressure on every pass and a flat, even finish. A single drum roller has one steel drum at the front and wheels at the back. It is lighter and turns more easily.
Compaction and Finish
Double drum is the better finisher. With two drums the surface comes out flat, which matters on asphalt and final layers. Single drum puts all its weight on one drum, which gives good ground pressure for soil and sub base, but the rear wheels do not compact. For a smooth top layer, double drum is the pick.
Tonnage
Weight decides compaction force. Our single drum unit is a 1.5 ton machine. Our double drum units are 3 ton machines. The heavier 3 ton reaches density in fewer passes and handles thicker layers, which suits larger road stretches. The 1.5 ton is enough for footpaths, patch repairs and confined areas, and it is easier to load and move.
Handling and Space
Single drum turns tighter and is lighter to manage, so it wins in narrow lanes, around manholes, and on small patch jobs. Double drum is steadier on open stretches and gives that flat finish, but it needs a little more room to work.
Engine Options
The lighter single drum, the Walk Behind Single Drum Roller with Honda GX390 Petrol (1.5 Ton) starting around ₹1,35,000 plus GST, runs a Honda GX390 petrol engine that starts easy and is simple to service. The double drum machines run diesel. The Greaves 10HP Diesel double drum (3 Ton) starts around ₹1,90,000, and the Chungfa 10HP Diesel double drum (3 Ton) starts around ₹1,85,000. Diesel suits the daily, heavier compaction these machines are built for.
Number of Passes
Compaction is about passes, not just weight. A heavier 3 ton double drum reaches the density you need in fewer passes, so on a large stretch it finishes faster even though it costs more to buy. A 1.5 ton single drum needs a few more passes on the same ground, but on small patch jobs that is no problem and the lighter machine is quicker to set up and move.
Cost to Own
The single drum is the cheaper machine to buy and the petrol engine keeps fuel simple. The double drum costs more up front but earns it back on bigger contracts where finish quality and speed matter. Think about the jobs you win most often, not the one big job you might win once.
Which Should You Buy
Choose double drum if you lay asphalt, finish road surfaces, or compact larger areas and want a flat result. Choose single drum if your work is soil, sub base, patch repairs and tight spaces, and you want a lighter machine that is easy to move and easy to start.
A Simple Comparison
| Factor | Single Drum (1.5 Ton) | Double Drum (3 Ton) |
|---|---|---|
| Drums that compact | One, front only | Two, front and rear |
| Finish | Good for soil | Flat, good for asphalt |
| Weight | Lighter, 1.5 ton | Heavier, 3 ton |
| Engine | Honda GX390 petrol | Greaves or Chungfa diesel |
| Best for | Footpaths, patch, tight spaces | Roads, asphalt, large areas |
