The twin cylinder, all-hydraulic pumps utilize exclusive Schwing features to pump concrete with up to 1.5-in. aggregate. The Cat diesel engine is a Tier 4 Interim model that capitalizes on Caterpillar’s strengths in designing power units for the demands of the construction industry. In this regard, the Cat-powered pumps benefit from up to 5 percent improved fuel efficiency, a boost in power and long-life durability. All Schwing stationary pumps are expected to be Cat powered for 2012.
The resulting performance of the Cat engines combined with the 5-in. pumping cylinders on the SP-305 is up to 30 yd./hour with up to 625 psi applied to the concrete. The SP 750-15 and 750-18 offer outputs to 70 yd./hour with up to 1,100 psi on the concrete. These capabilities translate to high utilization on projects requiring horizontal and vertical pumping. The compact size of the models means easy towing with one-ton trucks. A standard remote control provides convenience on the job. — Schwing America, 888/724-9464; www.schwing.com
