In a shaft sinking operation, there are typically two sets of rope attachments that need to be considered: galloway attachments and kibble attachments. Applications may vary, however, a minimum static factor of safety of 10:1 for both types of attachment strings is industry best practice.
The Galloway attachments typically consist of a rope end termination (typically a socket) and a mating components to connect directly to the Galloway. In some sinking arrangements, a sheave wheel exists on top of the Galloway and each rope is terminated at the surface collar. It is also common to implement a load-measuring device or “load-link” onto the Galloway set of attachments. The purpose of the load-link is to detect an unsafe “slack-rope” condition which may happen if a Galloway is inadvertently “hung up”.
