Balance Crane – A New Type of STS Crane in Development

STS container cranes have increased in height and outreach to accommodate ever-increasing ship sizes. But because the crane footprint has not changed, this has resulted in large wheel loads and tie-down loads on the wharf. In this paper, Kenton Lee, Simo Hoite, Lu Yan, and Anna Dix describe the Balance Crane, a concept Liftech conceived and developed with ZPMC, and present its design features, analyses, and study results.
