AbstractAn adjustable height table includes a base frame, a slider frame assembly, a generally planar support surface and a lifting mechanism. The main portion of the base frame is formed by welding three tubular components to form an H-shape. Each of the end portions of the H-shape include a mounting to support a swiveling locking castor. Above each castor there extends from the H-shaped main portion, a vertically extending tubular post. The slider frame assembly also includes an H-shaped main portion formed of three tubular members. Four vertically extending hollow tubular column members are attached to the H-frame so that they may telescopingly engage the four vertically extending posts of the base frame. A generally planar support surface is attached to the top of the four vertically extending columns located on the slider frame. Located between the central tube of the H portion of the base frame and central tube of the slider frame assembly, there is located a lifting mechanism, preferably a hydraulic jack. This jack can be actuated by a pedal mechanism to lift the slider frame assembly relative to the base frame. A second pedal is provided in the lifting mechanism to have the slider frame lower at a controlled rate of descent. Additionally an anti-sway bar is provided to prevent the lifting pump pedal from swaying side to side when in use.
