The disclosure concerns a mining roof support frame including at least one
hydraulic lifting ram which is mounted on a bridging member connecting
two base skids of the main frame, and which by way of a
pressure-generated force can be extended downward against a walking bar
of the walking unit of the mining roof support frame located between the
base skids. In accordance with the disclosure, the base skids lifting
device is connected with the bridging member such that it can pivot. With
walking unit ram pivot pins withdrawn only on one side, the base skids
lifting device can be pivoted out of the way about opposing pivot pins.
