Abstract: An adjustable chock for levelling and anchoring a machine to a foundation. The chock comprises a base element, a center element and a spherical washer, each is rotationally symmetric about a center axis. The center element is axially translational relative to the base element. The base element or the center element includes a mating surface for receiving the spherical washer. The chock has a center through hole for receiving an anchor bolt. The base element comprises an hydraulic connection point and a channel for hydraulic fluid. The channel is in connection with a chamber enclosed between surfaces of the center element and the base element, wherein in use, filling the chamber with hydraulic fluid exerts an axial pressure on the center element, causing an axial translation of the center element relative to the base element.

Abstract: An adjustable chock for levelling and anchoring a machine to a foundation. The chock comprises a base element, a centre element and a spherical washer (comprising either a concave or convex surface), each is rotationally symmetric about a centre axis. The centre element is axially translational relative to the base element. The base element or the centre element includes a mating surface (being the other of concave or convex) for receiving the spherical washer. The chock has a centre through hole for receiving an anchor bolt. The base element comprises an hydraulic connection point and a channel for hydraulic fluid. The channel is in connection with a chamber enclosed between surfaces of the centre element and the base element, wherein in use, filling the chamber with hydraulic fluid exerts an axial pressure on the centre element, causing an axial translation of the centre element relative to the base element.
