"Schwing concrete pumps have proven themselves over and over against their competitors. HDCE is a new company that has started with Schwing we have looked at the competitors and even purchased a competitor pump, but we have compared our costs to the other guys and Schwing beats them hands down. The new 46 meter is another tool in our shed that we use daily. The 46 is versatile with its small footprint and has the punch of a big boom. The smooth concrete delivery is perfect at the end of the boom. We have operators with 20-25 years’ experience and they love the 46."
