Versatile boom

Schwing has expanded its boom pump lineup with the S 20, which provides concrete contractors and specialty contractors with a versatile tool to expand concrete pumping possibilities while also performing conventional work. The four-section Double Z boom offers a total of 820 degrees of articulation with 270 degrees at both the third and fourth sections, allowing many possible configurations in confined spaces. Combined with a 12-ft., 7-in. unfolding height, the S20 can be used indoors, under overhead structures and in tunnels. www.schwing.com
