The PLCT ADVANTAGE is a unique trenching system that installs your desired utility or utilities in one continuous operation, with or without select bedding or backfill. The foundation of our Advantage is our fleet of specially fitted wheel trenchers and proprietary laying box technology. PLC Trenching Co. is the only company in the United States that has the lawful use of our laying box technology at this time.

The trencher itself is extremely versatile
with the following features:
  • 500 Plus Horsepower Caterpillar Engines.
  • 10 foot diameter cutting wheel with carbide teeth.
  • Trench widths from 6" to 15" & Trench Depths to Cover 6'
  • Trencher assembly remains horizontal at varying depths allowing the trench bottom compaction shoe to flatten and compact the bottom of the trench and pull our proprietary laying boxes.
  • Trencher assembly moves laterally so that the trench may be cut anywhere from outside of track to outside of other track.
  • Tilting chassis to operate on slopes.
  • Steel or rubber track pads.
  • Trencher assembly pivots so negotiating curves is no problem.
  • Ring gear powered cutting wheel allowing the axle to go below grade for greater depth capabilities and tremendous cutting forces in tough soil and rock conditions.
Our proprietary mechanical laying box technology
really sets us apart & with it we can:
  • Lay utilities to 6 feet deep and up to 15 inches wide, in soft soil or hard rock.
  • Place any number of flexible utilities in any desired configuration or position, with or without select bedding or backfill materials.
  • Installations can all be accomplished, in most cases, without major disturbances other than the trench width itself. This can be very important when working in and along roadways.
  • Quality of installation is assured especially when select bedding or backfill is installed.
