Sermac’s two newest concrete pump models, the Extreme 4ZR21 and the Scorpio 6RZ65, represent the extremes of the Ser-mac product line as the shortest and longest pumps offered, respectively. The four-section 4ZR21 combines the function and versatility of a Z-fold boom with the flexibility of a roll-and-fold, with a nearly 67-foot vertical reach, a nearly 54-foot horizontal reach, and an unfolding height just under 14 feet. The 6ZR65 offers more than 211 feet of vertical reach and more than 198 feet of horizontal reach in a six-section, RZ-combination. Both models include a cable and a radio remote, hopper gate vibrator, high volume and high-pressure water pumps, standard automatic lubrication systems on the pump kit, 12-foot end hose and a toolkit.
