La Miel Dam, Colombia

Towerbelt places RCC while Rotec Tower Crane does the lifting work

 

Towerbelt feeds Crawler Placer which in turn places RCC

Miel was the highest RCC dam in the world. We presented to the Brazilian contractor, Odebrecht, a system that had many unique characteristics. The Tower Belt is centrally located, and it was the first time we had the Tower Belt feeding the Crawler Placer, freeing the crane for other activity. We then had the difficult task of getting concrete from the mix plant to the Tower Belt through very mountainous terrain. The solution we devised was a tunnel that led directly from the mix plant to the Tower Belt. This worked fabulously. The contractor completed the work in record time, and the equipment left no carbon footprint. We were able to place concrete consistently, and at 600 cubic yards per hour; often for 24 hours a day.

 

Penn Forest Dam, USA

Two Rotec Port-O-Belt systems place RCC at Penn Forest Dam

This project, a water reservoir for the city of Bethlehem, Pennsylvania, used two independent custom Rotec Port-O-Belt Conveyor Systems to place RCC. Each system essentially consisted of a long line Port-O-Belt (POB) conveyor, a tripper conveyor and a plow conveyor. The long line conveyor transported the RCC straight from the Pug mill plant to the tripper conveyor located along the axis of the reservoir “dam.” The tripper then transfered the RCC to the plow conveyor which in turn discharged material in windrows on the dam surface. One system was required at each end of the project. The system was unique in that the tripper and plow conveyors could travel the length of the reservoir allowing dozing and compaction to continue during RCC placement.
