Putzmeister 42Z-Meter Truck-Mounted Concrete Boom Pump

Designed with the operator in mind, the 42Z delivers greater payload capacity and longer pump life with great performance you expect from Putzmeister. With a five-section Z-fold boom that gives you 136 feet 6 inches of vertical reach, it still comes in at 66,000 pounds and goes where most 40-meter class boom pumps cannot. Don’t be fooled by its light weight – the pedestal sub-frame bolt connections make the frame more flexible to withstand torsion from the pump force. And with 30 percent more deck space, it can carry more equipment to the job site.

Exclusive Ergonic® Control System

Ergonic Brochure

• 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.

By improving the pedestal construction with a bolt connection and simplifying the turret design, newer Putzmeister boom pumps can better handle the pump’s torsion forces resulting in less down time and lower maintenance costs.

Our exclusive Econo-Gear™ helps achieve greater fuel efficiency by performing the setup, pumping and cleanup operations in a gear that allows for the use of a lower engine speed. In addition to fuel savings, Econo-Gear also reduces stress on wear parts and lowers noise levels.

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.

Designed with the operator in mind, all newer Putzmeister models are lighter weight to offer greater capacity for payload, water and fuel. The new design also offers significantly more deck space for job site equipment and ease of movement around the deck

On all newer Putzmeister boom pumps the pipe layout features only a single bend in the turret and two elbow sizes – 45-degree and 90-degree – parts commonality has been increased and wear has been decreased. Additionally, the pipe hanger brackets have bolt connections for extended life and easier wear.
