Improvements introduced in hydraulic rams and the like, incorporating a hydraulic cylinder and ram device and, in particular, a well strut or other hydraulic and hydraulic ram-type roof bracket adapted to receive a hydraulic fluid from a source of supply to relatively low pressure by a main cylinder inlet with means for the control of said fluid, and in such a way extend to the load and then put under overpressure to a value within the relatively low potential of the supply, incorporating to said device a medium hydraulic pressure intensifier provided so that the fluid control means come into action following the relatively low overpressure of the device, thus intensifying the overpressure to a relatively high value.
