Abstract
A comprehensive study of high-speed hoisting in deep shafts was conducted. The study (1) demonstrated the practicality of lightweight skips, (2) developed a guide alignment measuring system, (3) identified the factors affecting skip-guide, skip-rope dynamic interaction, and (4) presented the economic benefits of using lightweight skips. Two lightweight cylindrical skips, one of aluminum and one of fiberglass, were designed, fabricated, and tested. A self-contained guide alignment measuring system was conceived, fabricated, tested, and used to make field measurements in an operating shaft. A computer program (skip II) was used to find the effect of misaligned guides for any size skip, empty or full, at any speed. An economic analysis of lightweight cylindrical hoists focused on the impacts on capital and operating costs in hoist plant and rope life.
