Encore rebuilds Manitowoc 4000W
By Laura Hatton30 January 2014
A 4000W Manitowoc lattice boom crawler crane has been refurbished at Manitowoc’s Encore branch in Passo Fundo, Brazil.
The 38-year-old crane, owned by Brazilian construction company Odebrecht, has worked at the Estaleiro Paraguaçu shipyard in Salvador for several decades.
“Odebrecht wished to keep the model in service because of its freefall system, which is used for pile-driving operations. The company also valued the crane’s easy maintenance and familiar mechanisms,” a company spokesperson explains.
The Encore team remanufactured the boom hoist, refurbished the travel lock, rebuilt the main drive shaft (including new clutches and bearings), redesigned and fitted a new roof with new plates and reinforcements, and gave the crane a new paint job. In addition, the chassis was inspected and the engine was exchanged for a new Cummins model. Following the repair work the crawler was fully tested and certified.
Odebrecht took delivery of the refurbished crane in September.
Rodrigo Stefanini, Manitowoc Encore senior manager, Latin America, said, “We were able to completely rebuild the Manitowoc 4000W for Odebrecht, restoring this solid, reliable crane and hopefully giving it another 38 years of dependable service.”
The refurbishment took six months to complete and cost 75 % less than purchasing a new crane, a spokesperson from Manitowoc added.
