ABSTRACT:
A hoisting system for use in elevating personnel or other materials preferably within a mine, or other low level installations, incorporating a capsule which is suspended by a singular cable that is fed out from a winding drum, a tension weight suspended below and in alignment with the capsule, being supported by the same cable, and a jib-crane assembly located at the upper reaches of the hoisting assembly to provide for feed out of the cable through its sheave assembly to furnish, at least initially, a lowering of the tension weight to its lowermost extent for coming to rest upon a base, while thereafter the continued unwinding or rewinding of the cable provides respectively for the lowering or raising of the capsule between various levels for effecting transfer of personnel and materials along the shaft heighth.
In the process of operating this hoisting system, the unwinding cable initially lowers the heavier tension weight, due to its weight, first down into the depths of the mine, or the like, until it comes to rest upon the base, and then further unwinding of cable allows for the capsule itself to be lowered stably under the guidance of the singular cable that also embraces its sides, and thereby preventing capsule sway or slack, whereafter the capsule may then be raised or lowered within the shaft under the control of this singular cable.
