Putzmeister’s most popular truck-mounted boom pump size, the 38Z is specially engineered to extend the 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.
