drop warwicks
Steel joists hinged to a substantial cross joist in the roof that are held up by a stirrup during normal running. If a tram runs away down the incline, the stirrup is disengaged by 1006 means of a wire operated from the top of the incline; one end of the hinged joist falls into the rail track and arrests the runaway.
