Putzmeister Truck-Mounted Boom Pumps
BSF 42-5
Redesigned for Longer Life and Increased Payload Capacity
Overview
Built for the way Texas crews work
The BSF 42-5 is designed keeping the operator in mind. It functions with increased payload capacity and longer pump life. You can expect better performance from this truck. With a five-section Z-fold boom that gives you 136 feet 6 inches (41.6 meters) of vertical reach. The BSF 42-5 comes in at less than 67,000 pounds (30,287 kilograms) and goes where most 131 feet 3 inch (40-meter) class boom pumps cannot navigate. But 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. Ideal for high-pressure applications, its S-Valve handles the most extreme mixes with ease. This one is built for years of durability. Its thick-walled valve construction features exclusive hard-chromed concrete cylinders and multi-piece piston cup design. It also boasts of 30% more deck space which means it can carry more equipment to the job site.

Ideal for high-pressure applications
