When considering an excavator compactor, heavy equipment operators have a variety of choices, but it might be said there are two basic types. One is the vibratory compactor and the other is a roller compactor. Both have advantages and disadvantages, but it’s really a case of choosing the right tool for the job. One is not necessarily superior to the other.
Also remember there is a difference between a vibratory compaction plate and a vibratory compaction bucket. The latter basically offers two tools in one – an excavation bucket that also has the action of a vibratory plate.
Vibratory compaction buckets allow for high degrees of efficiency in specific situations, especially when digging trenches for sewer work or site preparation. It’s the perfect tool for multipurpose jobs especially in extreme conditions. They work best in wet, granular or sandy conditions. They are perhaps not the best choice for digging in heavy clay, however. In those cases, a roller compaction device offers much better action in breaking up clumps of clay and layering all soil types in order to eliminate soil bridging.
But back to the combo-tool for a minute – the vibratory excavator bucket. It saves time by allowing the operator to dig and place backfill with uniform lifts each time and then seamlessly applying the vibrating compaction to get the job done all in the same motion.
By contrast, if your using a vibratory plate to do the compaction, you must first dig with a bucket and then switch utilities. That means detaching the bucket and attaching the plate vibrator. This is not an issue if the plate vibrator is used with another piece of equipment, but you still have to perform digging and compacting separately.
Some operators prefer to use a roller-type excavator compactor in most or all situations. Again, rollers can be combined with buckets to make for a multifaceted tool the eliminates the need to switch between tools.
