What is a reduced swing excavator?
Reduced-tail-swing excavators are ideal when digging and backfilling trenches in a confined area. The trend with reduced tail swing excavators is on the smaller side of the crawler excavator spectrum, typically between the 14- and 30-metric-ton size class.
What is a swing boom excavator?

Caterpillar’s 335F CR is the manufacturer’s largest compact radius excavator available. The reduced swing radius and heavy lifting capabilities suit this machine for rehabilitation work on roads and bridges where work space is at a premium.
What is tail swing radius?
The tail swing radius on the DX140LCR-3 is only 5 feet, which results in a tail swing overhang of just 9 inches over the side of the machine, making it an ideal candidate for working in congested jobsites such as streets, highways and rail lines without blocking traffic in adjacent lanes or tracks.
What does conventional tail swing mean?
Conventional-tail-swing excavators have a rear counterweight profile that extends beyond the machine’s steel tracks when the house rotates, optimizing performance in digging, loading and lifting applications.
