In a hydraulic pit prop A having an elongated cap 2 positioned thereon by ball and socket joint 5, 6 the cap is automatically centred on the prop when the retracted latter is from the roof by a torsion and flexion bar 8 interconnected therebetween. At one end the bar 8 is connected to a strip 16 adjustably mounted on the cap 2 so as to impart an initial bias to the cap setting.
