Putzmeister 38Z-Meter Truck-Mounted Concrete Boom Pump

Putzmeister’s most popular truck-mounted boom pump size, the 38Z is specially engineered to extend your pumping season. With the flexibility of the Multi-Z boom and the reach to place concrete exactly where you want it, the 38Z also comes as a three-axle, frost-law-compliant unit. The tag axle is easily removed when it’s not needed. Compact outriggers give you quick setup in tight locations. This is the only four-section, 121-foot 9-inch Multi-Z boom on the market with X-style outriggers.

• 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.

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.

  • Perfect when frequent boom transfers are required.
  • Convenient two-piece slewing head features color-coded quick- disconnect hydraulic fittings and easy alignment of the boom to the pedestal pin.
  • The pedestal can be left on the tower to reduce the "fly" weight by 4,850 pounds.
  • Adapts to most Putzmeister pumps produced since 1985.
  • Can be installed with your initial boom pump order or added later.

Step 1: Hydraulic Quick Disconnect
Step 2: Detach boom and lift
Step 3: Fly boom from truck to tower
Step 4: Position, pin and pump

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.
