Utilicor Technologies
The MPX (Multi-Platform Coring Unit) easily mounts on a variety of platforms – pickup trucks, flat deck trucks, service bodies or trailers. Built on a universal base, the MPX fits within the width of even the narrowest of pickup trucks. A simple bolt down pattern allows for easy swapping between vehicles. The new, dual stage mast deployment system accommodates a variety of deck levels or trailer heights. Powered by a 36-hp Kohler gas engine, the MPX’s hydraulic system creates over 18 GPM of hydraulic flow at 2,200. The MPX also accommodates up to a 24-inch diameter coring drum (18-inch is standard). The coring drum can be accurately positioned perpendicular to the horizon to ensure that every core can be easily extracted and reinstated using Utilicor’s Utilibond keyhole core bonding compound. The MPX comes equipped with a 100-gallon water tank, a high pressure wash system and an optional core lift device with a 500 pound capacity, as well as a Glycol winterizing system for operations in colder climates. 888.572.6666,
