Belo Monte Dam

Belo Monte Dam

Belo Monte Dam is a hydroelectric dam set up on the Xingu River, in the state of Pará, North of Brazil. It will become at its inauguration the second largest dam in Brazil and just the fourth largest dam in the world, with a total maximum capacity of 11,233 MW.

For this major dam project, Dextra Do Brasil continuously delivered to contractors its Rolltec mechanical rebar splicing solution between 2011 and 2016.

Rolltec is the most popular rebar splicing solution in Brazil, providing a competitive alternative to lap splices.

A total of 250,000 couplers have been used on the Belo Monte dam, used across all parts of the structure.

The rebar preparation is supported by a unique light equipment, operated by a single operator.

The Rolltec machine is relatively easy to transport and convenient to install even on most remote locations such as dam construction sites.
