Putzmeister Truck-Mounted Boom Pumps
BSF 27-4
Flexibility with the BSF 27-4 - Ideal for any application
Overview
Built for the way Texas crews work
The BSF 27-4 is the perfect solution for pumping in inner-city areas, concreting bridges, hose applications, and much more thanks to the TRC pedestal.
The newly designed BSF 27-4 boom improves flexibility with a 100deg a-angle and provides the highest boom on 2-axle trucks. Boom vibrations and wobbling are reduced by laying the delivery lines in neutral and straight arms. Service-friendly access, all pipe on one side of the boom, standardized pipe bends, and screwed pipe supports allow for quick delivery line replacement.
Our TRC design (Trapezium Compact) is a further development of our TRD system - now even more compact with double telescopic support legs with a 10% smaller support area. The TRC not only saves a lot of space - 19.7" to 23.6" compared to the TRD - but also offers the option of infinitely variable support. The stability of the unit is also improved, supported by a reduced weight that allows for a higher payload.
Lowest possible support area for inner-city pumping
Flexible double telescopic support legs provide stability in any position
Rear support cylinders for shorter paths in the working area
Generous space for storage containers and hoses
