ABSTRACT:
Apparatus for mounting ancillary equipment between two relatively movable members of, for example a mine roof support, comprises two substantially parallel arm members pivotally mounted between the two relatively movable members, two rotatable members secured one to each arm member, and at least one cross member pivotally mounted at opposing ends to the rotatable members. The members of the apparatus are arranged so that the axes of rotation of the rotatable members, the axis about which the arms pivot, and the axes about which the cross members pivot, are each transverse to the other two. This arrangement can be used to provide a mine roof support with an operating platform having mountings which have a degree of movement akin to a universal joint.
