Four Manitowoc Cranes Help Rebuild Wharf in Working Shipyard

The challenge:

Demolishing and rebuilding a shipyard wharf while the port remained fully operational

The players:

Irving Equipment Limited

The process:

As part of the Halifax Shipyard Modernization Program, a wharf at the Halifax, Nova Scotia, shipyard was demolished and rebuilt. Demolition of the buildings and foundations, as well as construction of the wharf, occured within the fully operational port.  The new wharf will measure about 850 feet in length and 65 feet in height.

The project, which began in May of 2013 and wrapped up in January 2014, involved the use of two 120-ton Manitowoc 12000 crawler cranes rigged with 120- and 140-foot booms. A 230-ton Manitowoc 888 crawler crane with a 140-foot boom and a 300-ton Manitowoc 2250 crawler crane with a 160-foot boom were also used.

Operated by Saint John-based Irving Equipment Limited, this trio of cranes was chosen for their long reach and high capacity capabilities.

The Manitowoc 2250 operated a Berminghammer Drill, which was used to drill overburden that consisted of marine sediment, small boulders and rock sockets; to bore through steel debris; and to position temporary falsework frames. The two Manitowoc 12000s were operating as support cranes on the site.
