Abstract: A hydraulically operated barbecue cooking apparatus comprising a superstructure defining a housing having a firebox well arranged to receive a vertically adjustable firebox which is generally supported by a water-operated hydraulic lift, the lift being disposed in a cavity formed below ground level whereby the firebox can be adjusted upwardly or downwardly within the full length of the housing firebox well. The hydraulic lift has a stabilizing guide member attached between the firebox and the lift, the lift being operated by a control valve which directs water pressure into the cylinder housing to lift the piston, and allowing the water to drain when the piston is lowered together with the firebox.
