REPAIR AND REFURBISHMENT Ӏ CASE STUDY


REVIVING A LEGEND


A major refurbishment project taking almost two years has fully restored a unique crawler crane in Brazil, ready for its next mission.


Restoring a crane more than 40 years old is no easy task – especially when it has stood idle on the Brazilian coast for over six years, exposed to the elements. Eletronuclear, the Brazilian


state power company, originally purchased the Manitowoc 4600 lattice-boom crawler crane back in 1982. Its primary task was helping to build Angra 2, the second reactor at the Angra nuclear power plant in Rio de Janeiro.


The crane has been at the site for the last 40 years...


For 40 years, the Manitowoc crane has been part of the landscape at the Central Nuclear Almirante Álvaro Alberto complex, where the three Angra plants are located. After building Angra 2, in 2000, the crane was assigned to build the third reactor, but the project was shelved. In the early 2020s, work


resumed on Angra 3. Its siblings already provide about 3% of Brazil’s energy needs, with Angra 3 expected to generate sufficient power to supply another 4.5 million inhabitants in the region.


...for around six years, however, it had been unused
