Abstract
A stop block system for locking hydraulic cylinders is provided. The stop block system includes a plurality of axially adjacent layers that are arranged co-axially. The layers include a top layer having a bearing surface for receiving a load, one or more spacer rings for adjusting the height of the stop block system and transferring the load from the top layer to a base layer and a base layer for centering the stop block system and transferring the load from the spacer rings to a surface on which the stop block system rests. Each annular layer may be made up of two or more annular c-shaped components. The two or more components of one layer may be rotationally offset from the two or more components of axially adjacent layers.
