Hog Island Cranes, Historical industrial cranes in Trenton, US

The Hog Island Cranes are two large locomotive-type gantry structures positioned along the Delaware River waterfront in Trenton. These steel frames stand side by side and remain prominent features of the industrial harbor landscape.

The cranes were built in 1917 by the McMyler-Interstate Company of Cleveland, Ohio, for the Hog Island shipyard in Philadelphia, where they helped produce warships during World War I. In 1930 the two cranes were sold as government surplus to the municipal government for $5,000, a fifth of their original cost, and installed at the Trenton Marine Terminal in 1932. They were overhauled in 1952.

These structures represent how Trenton once served as a major industrial hub with heavy machinery dominating its waterfront. They stand as reminders of an era when such equipment was central to the city's identity and economic life.

Visitors can view these cranes from along the Delaware River waterfront and see how ships were once loaded. The best views are found from various points around the harbor area where you can walk around the structures.
