A fleet of Manitowoc crawler cranes is helping to demolish and rebuild a wharf at Halifax Shipyard in Nova Scotia, Canada.
Once completed, the facility, which is being redeveloped as part of the Halifax Shipyard Modernisation Program, will be used to serve the Royal Canadian Navy’s combat fleet. The Manitowoc fleet is being operated by Saint John-based Irving Equipment Ltd, and includes two 120-ton 12000s, one 230-ton 888, and a 300-ton 2250.
“Having the proper equipment to do the job in an efficient and effective manner is one of the keys to Irving Equipment’s success,” explained Andrew Folkins, manager of the firm’s pile-driving division.
“That’s along with matching experience and the ability to the project’s requirements,” he added.
Equipped with a Berminghammer attachment, the Manitowoc 2250 is being used to drill into the overburden, which is made up of marine sediment, small boulders, and rock sockets. The unit is also helping to bore through steel debris, and to position temporary falsework frames. The pair of 12000s, meanwhile, are operating as support cranes on the site.
To make matters even more challenging, Halifax Shipyard is to remain in use while work is taking place. The facility will remain fully operational throughout the demolition of the buildings and foundations, and during the construction of the wharf. For this reason, Irving Equipment carefully selected the Manitowoc models based on their respective reaches and capacities.
Once finished, Halifax Shipyard’s reconstructed wharf will stand 65m high, and will measure 260m in length. The project is scheduled to be completed in Q1 2015.
