Abstract
Apparatus for anchoring a mining installation to the floor of a mine working includes an anchor beam and means for anchoring the anchor beam. A trolley is mounted on the anchor beam for longitudinal movement relative thereto. A guide skid is pivotally connected, at one end, to the trolley and one end of a support skid is pivotally connected to the other end of the guide skid. The other end of the support skid is pivotally connected to a support table for the mining installation, whereby the support table can pivot in a vertical plane. A support strut pivotally connected to both the guide skid and the support table holds the support table firmly at a given inclination.
