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.

- centering the base around the hydraulic cylinder shaft;
- arranging one or more spacers around the hydraulic cylinder shaft atop the base, each of the one or more spacers arranged co-axially with the base;
- and
- arranging a top bearing surface on top of a top-most spacer of the one or more spacers.
A kit comprising;
- one or more stop block systems for locking hydraulic cylinders on cargo ships;
- and
- a container for receiving and transporting the one or more stop block systems for locking hydraulic cylinders on cargo ships;
- wherein each stop block system comprises:
- a base for centering the stop block system;
- a plurality of spacers axially alignable with the base;
- and
