If you need to compact soil on a site with trenches or difficult soil, then the trench roller could be the machine for you. Trench rollers are smart machines with in-built technology which make them ideal for compacting clay, muddy soil or loose sediment.
These machines are pedestrian-operated, either manually from behind or more commonly via radio-frequency remote control. Remote controlled trench rollers allow the operator to stand comfortably out of the trench and operate from above.
Newer models of the trench roller are equipped with infrared technology to reduce signal loss during operation. This makes for safer compaction and means that multiple rollers could be used on the same site without worry of interference. Some machines also have technology that triggers them to stop moving and vibrating when the operator comes near the machine. This ensures the machine is only working where you need it to and in the desired location on site. Of course, older models won't be as equipped with this type of technology so it's important to do your research to find the right machine for your project.
Generally, a trench roller will work by moving and vibrating along the soil. They usually feature padded drums for a deeper compaction, and sometimes have an articulated joint which enables them to continue operating despite curves or obstacles in the way. These machines have weights in the drum attached to a shaft which rotates and causes vibration to press down into the soil for improved machine stability and compaction.
Another great feature of the trench roller is the width of the machine. These machines are generally built quite narrow to ensure they can be used on tight work sites and in narrow trench applications. Some models also offer 2 different working widths which makes the machine more versatile. These working widths are achieved by the addition of drum extenders which can increase the drum width by up to 10 inches in some cases. Of course, not all machines have this ability, so make sure you check with the dealer, seller or hire company about your particular machine.
Not only can trench rollers work on narrow sites, but they can also usually operate in forward and reverse. This is ideal when working in such confined spaces as it allows the machine to easily perform its passes back and forth without the operator having to manoeuvre the machine into position. This also allows for consistent and even compaction of the soil.
