Abstract
A chain for protecting electric and/or hydraulic supply cables to a mining machine repeatedly traversing to and fro. The links each comprising two elements which when connected define a passageway for the supply cables and which can be at least partially disconnected to permit access to the passageway, both the elements being pivotally attached to the elements of neighboring links.
Claims10
A link adapted to be pivotally attached to similar adjacent links to provide a chain for protecting a plurality of flexible supply components leading to equipment which in use repeatedly traverses to and fro, the link comprising two elements in engagement with each other, one of said elements defining an open sided passageway for containing said plurality of flexible supply components which elements when connected define a closed passageway around any such flexible supply components, the open side forming a part of the closed passageway when said elements are connected, and which other of said elements can be at least partially disconnected to permit access to the passageway, both the elements having means capable of being pivotally attached to elements of adjacent links.
A chain for protecting a plurality of elongate flexible supply components leading to equipment which in use repeatedly traverses to and fro, each link of the chain comprising two elements in engagement with each other one of said elements defining an open sided passageway for containing said plurality of flexible supply components, which elements when connected define a closed passageway around any such plurality of flexible supply components, the open side forming part of the closed passageway when said elements are connected, and which other of said elements can be at least partially disconnected to permit access to the passageway, both elements having means for pivotally attaching to the elements of adjacent links.
