Putzmeister 20Z-Meter Truck-Mounted Concrete Boom Pump

Putzmeister’s 20Z is an affordable addition whether you are just starting out or adding more flexibility to your fleet. With its compact design, the 20Z has exceptional maneuverability for busy urban job sites. Yet, it has the power you need for a wide variety of applications. The versatile four-section Z-Fold boom with 63 feet 10 inches of vertical reach makes it easy to place concrete in otherwise hard-to-reach places. The standard swivel elbow off the back-end with a 90-degree pivot allows you to use the 20Z as a City Pump.

The Ergonic system features the Ergonic Graphic Display (EGD), a three-inch square color LCD screen on the modular control box. When the equipment is on, the main menu shows:
• Hydraulic fluid temperature
• Operating hours
• Delivery pressure/delivery pressure limit
• Delivery rate/delivery rate limit

Putzmeister boom pumps feature a single proximity switch in each position. Redundancy is not necessary because the Ergonic Pump Control System can override the switches if necessary.

All Putzmeister boom pumps feature the robust yet lightweight EZ Clean Out RS 909 hopper, which is engineered for performance and durability. Offering 19.4 cu. ft. (550L) capacity, the hopper uses one hard-faced remixer paddle motor and grate-mounted vibrator. The grate is constructed of high-strength steel with welded connections for a long wear life.

An innovative RFID safety switch incorporated in the hopper disables the machine when the grate is opened.

Putzmeister pumps feature an exclusive free flow hydraulic system that performs to higher standards at lower cost than other pumps. Its valve-less intelligent monitoring system takes oil into the drive cylinders with no loss of pressure to enhance the pump’s service life while increasing power and convenience.

Low ceiling heights and unusual concrete placing challenges are easily tacked with the versatility of Putzmeister’s Z-Boom design. Booth the Multi-Z and Z-Fold configurations can begin a pour before the boom is fully unfolded. Additionally, these four- and five-section booms can easily maneuver around obstacles to achieve the maximum reach and flexibility possible.

Putzmeister’s HBC-Radiomatic power boost and frequency hopping remote control system ensure minimum interference with other frequency transmitters. A fully proportional cable remote is also standard. Unlike other systems, the radio and cable remote systems are completely independently, offering redundancies to ensure complete proportional operation with either control.
