Putzmeister 70Z-Meter Semi-Trailer-Mounted Concrete Boom Pump

The largest boom pump on the market takes concrete placement to the extreme. The 70Z has 227 feet 4 inches of vertical reach and 212 feet 11 inches of horizontal reach with a five-section Z-Fold boom for maximum flexibility – including the ability to be deployed in either the Z position or the A-frame configuration. Despite its powerful size, the 70Z has the same smooth and reliable pumping performance you expect from Putzmeister along with a tight turning radius of just 59 feet for easy maneuverability on the road or on the job site..

• A smoother pumping process
• Reduced component wear
• Low fuel consumption
• Fewer vibrations in the machine and boom
• Fully electronic control of the concrete pump
• Fewer hydraulic components
• Optimized output for greatest efficiency

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 One-Sided Support (OSS) outrigger system allows the boom pump operator to reduce the outrigger span on the non-working side of the unit. Through a series of sensors, OSS safely achieves set up in confined areas without full outrigger deployment. The sensors maintain a defined working envelope that prevents the operator from positioning the boom outside of a safe operational range.

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.
