GOMACO has taken the Commander III four-track to the next level in concrete slipform paving. It now offers the new IDBI attachment for dowel-bar insertion. This attachment is an independent unit providing dowel-bar insertion behind a paver. The attachment is powered by its own C4.4, Tier III, diesel Caterpillar engine with 91 hp at 2,300 rpm. A CAN cable connects the IDBI’s controls to the controller on the Commander III and allows the two systems to communicate.
