Plate Compactors Get Onboard
November 18th, 2009 by Kim Berndtson. Posted in Construction Equipment Network Blog.Onboard compaction monitoring systems aren’t just for large soil and asphalt compactors. The technology has also made its way into walk-behind reversible plate compactors for trench and utility work and landscaping applications. It essentially works the same way - response or rebound is measured, then fed back to the operator.
BOMAG offers the technology on its plate compactors, as does Weber Machine, Inc., which offers COMPATROL technology on its 900-lb. and larger machines. It will be introducing the technology next spring on its 600-lb. models. “About 50% of the units we sell are equipped with the device,” says Peter Witt, Weber’s president, “and that number is continuing to grow.”
Like systems on the larger units, COMPATROL saves time spent on compaction. “The system tells you when you’ve achieved maximum compaction so you can finish in less time,” Witt states. “Without the technology, in the best-case scenario, you may just waste time. In the worst-case scenario, you can over-compact the soil. It also reduces time spent reworking weak spots after testing, simply because there will not be any weak spots.”
About a year ago, Paul Caruso, owner of Caruso Landscape Design in Braintree, MA, purchased a Weber CR7 plate compactor with the technology for compacting the base for a 19-ft. retaining wall. “I wanted to minimize the guesswork as to whether or not the backfill was compacted properly to reduce my liability and increase efficiency,” he says. “With retaining walls, failure can be a problem if compaction isn’t done properly, and there was a lot at stake with this project.
“Plus, if the compaction control monitor is reading at the level you need, then you can do the [verification] test,” he continues. “You’re not calling in unnecessarily for a compaction test when you don’t know if you’re done. Even on jobs that don’t require a test, it’s good to know that you’re reaching full compaction.”
