Vale Canada Limited
Vale initiated BESTECH to conduct feasibility studies for upgrading the hoisting system to enhance efficiency and reduce downtime during plant construction.
The initial FEL 1 study assessed relocating the hoist house and replacing the single deck cage with a double deck cage. Subsequent FEL 2 and FEL 3 studies refined the project scope by evaluating options and construction requirements for a new hoist system within the existing infrastructure.
SCOPE
The review revealed that modifying the shaft and stations for a double-deck cage was impractical. Thus, the preferred option was a new single drum hoist designed for under-winding to ease rope maintenance. This required replacing mechanical, electrical, and control systems for seamless integration and operation. The design scope included preliminary platforms, shrouding, a new electrical room block wall, a redesigned hoist electrical room layout, and a mechanical brake system upgrade.
OUTCOME
The studies culminated in a strategy for installing a new single drum hoist, optimizing the existing hoist house while addressing all necessary upgrades. This approach minimized downtime and ensured the new system would meet operational requirements. The integration of new technology and upgrades will significantly enhance the safety and efficiency of hoisting operations, providing a robust solution aligned with the plant’s long-term goals.
