The TracStar 1200 self-propelled, track-mounted fusion machine from McElroy Manufacturing has an advanced emission control engine that burns ultra-low-sulfur diesel to meet the EPA’s latest Tier 4 standards. The cowling has been redesigned so that technicians have better and quicker access to the engine for maintenance. It butt fuses pipe from 16 to 48 inches O.D. and can traverse most any terrain, including mud, loose soil, snow and grades up to 30 percent. It is self-contained with an onboard generator for powering the hydraulic pivoting heater and facer. The three- or four-jaw convertible carriage is easily removable for in-ditch use. It comes with hydraulic outriggers for machine stability and leveling, an ergonomic operator platform and remote engine stop/start capabilities. 918/836-8611; www.mcelroy.com.
