The invention relates to a kibble tipping arrangement, which is used in a mining operation where a kibble (12) is vertically displaceable along a kibble displacement path to transport excavated material is a vertical mine shaft to the surface. The kibble tipping arrangement includes at least one catch (24) which is transversely displaceable between a non-interference position in which the catch does not interfere with the kibble (12) in the kibble displacement path and an interference position in which the catch (24) is capable of being engaged by an engagement formation (28) on the kibble (12) to allow the kibble (12) to top and the excavated material to be dumped from the kibble (12). The kibble tipping arrangement further includes kibble alignment means, which consist of a locator and a positioner, for aligning the kibble's engagement formation (28) with the catch (24).
