Truck-Mounted Concrete Boom Pump
Fully removable, Putzmeister’s modular bolt-on flatpack and hydraulic system combine versatility and servicing convenience. Pump cells can be switched out as jobs require or when maintenance is necessary. This feature also provides easier access to the S-Valve and shift cylinders.
Switch gears and save with Putzmeister’s patented Econo-Gear.TM The exclusive design allows the Mack chassis engine to run at a lower rpm, achieving less stress on wear items, lower noise levels and reduced fuel consumption. Econo-Gear makes a significant impact on job site safety and profitability with an estimated 10-15% savings.
RS 907A Hopper
Putzmeister’s EZ Clean Out RS 907A hopper is engineered for performance and easy maintenance. Offering 19.4 cu. ft. (550L) capacity, the hopper features hard-faced remixer paddles and vibrator. The unique design of the impact resistant polyurethane splash guard protects the unit from splattering during pumping and folds down and latches to cover the hopper during transit.
