20ZR-Meter
Unmatched Versatility in a Compact Design
Whether you are just starting out, or adding more flexibility to your existing fleet — Putzmeister’s 20ZR is a cost-effective option. The compact design allows easy maneuvering through busy, urban job sites. The versatile four-section ZR-Fold boom, with 63 feet 10 inches (19.46 meters) of vertical reach can operate in challenging places including areas with low ceilings.
This is possible because both the Multi-Z and Z-Fold configurations can begin a pour before the boom is fully unfolded. A standard swivel elbow, off the back-end with a 90-degree pivot, also allows you to use the 20ZR as a City Pump.
Another integral component is the Ergonic Output Control (EOC) which reduces fuel consumption, wear and noise. An easy-to-use graphic display lets you keep track of hydraulic fluid temperature, operating hours, delivery pressure and limit, and delivery rate and limit.
