A fleet of Manitowoc crawler cranes is being used in Halifax, Nova Scotia, Canada, demolishing and rebuilding a wharf at the Halifax Shipyard. The construction is part of the Halifax Shipyard Modernization Program and will serve the Royal Canadian Navy’s combat fleet.
On site are two 120-ton Manitowoc 12000 crawler cranes, rigged with 120- and 140-ft. booms; a 230-ton Manitowoc 888 crawler crane, set up with a 140-ft. boom; and a 300-ton Manitowoc 2250 crawler crane, rigged with 160-ft. of boom. They are being operated by Saint John-based Irving Equipment Ltd.
The Manitowoc 2250 is operating a Berminghammer Drill, which is used to drill overburden that consists of marine sediment, small boulders, and rock sockets, to bore through steel debris, and to position temporary falsework frames. The two Manitowoc 12000s are operating as support cranes on the site. The new wharf will measure about 850 ft. in length and 65 ft. in height.
While the cranes worked, the shipyard remains in operation, meaning demolition of the buildings and foundations, as well as construction of the wharf, are occurring within the fully operational port.
“Having the proper equipment to do the job in an efficient and effective manner is one of the key’s to Irving Equipment’s success,” said Andrew Folkins, manager of pile-driving division at Irving. “That’s along with matching experience and ability to the project’s requirements.”
