Head & Deflection Sheaves
Our Sheaves can be designed with split-type or segmented construction for ease of handling and installation in limited space. Alternative designs include unlined, steel-lined and polyurethane-lined to satisfy all applications and conditions.
FLSmidth's 15-ft diameter Compensating Sheaves are among the first, and are the largest supplied for a "Blair" type Hoist Application. The Blair arrangement uses two sheaves side by side, for two connections to the skip or cage. This provides deep hoisting capability with two ropes, thus eliminating the requirement for a safety mechanism and wooden guides. Economical rope guides can instead be used. Our Compensating Sheaves ensure hoist rope tensions and lengths are equally maintained via our supply of load cells and hydraulic power package.
Our Sheaves typically outlast the mineshaft that they are installed in and are often recycled and reused in a new shaft. We have replaced sheaves that were manufactured by others that had not lasted even to the life of the first shaft. The success of our sheaves is due to high quality manufacturing and design practices. Solid modeling and finite element analysis are standard design procedures and the designs exceed all applicable codes. Raw materials and the final product are subjected to extensive non-destructive testing.
