Abstract
This paper examines the function that the compensating sheaves perform when used to equalise the load on the ropes of a Blair Hoisting system. Compensating sheave systems have been used for many years with little change to their basic design concept. This paper examines the systems used, analyses the actual loads that may be expected, and estimates how well the systems can be expected to perform. There are several perceived limitations to the existing designs and their implementation. As a result of these perceptions, new concepts and developments in this area are moving the control of such systems from passive to active types of control. These developments are discussed and commented upon, and a way forward for such designs is suggested.
