For the demands of the largest construction sites, the 63 Meter 5-Section RZ boom pump answers the call. Capable of pumping concrete for large projects, operators can trust that it will get the job done. Available with a Freightliner, Mack, or Peterbuilt chassis it has a maximum output of 237 cu yds/hour. The smaller switch panel at the rear of the pump minimizes clutter and eliminates long wiring looms that deteriorate with time. Alliance Concrete Pumps.
