Abstract: Device for the handling and storage of boats in a vertical dry dock. The boats (16) are removed from the water (7) via forks (13) which slide in a sliding fork-shaped system (12) carrying a cradle (10). The forks are displaced via a motor driven rack and pinion (14) system. The run of the rack and pinion system is limited by sensors (5 et 20). The entire mechanism is supported by a structure (8) which carries a tower (9) and a sliding fork-shaped system (12) that enables the cradles (10) to be deposited in berths (2, 2a). A rolling bridge (6) enables the entire assembly to be moved along X, Y and Z axes. The device is specifically useful for vertical dry dock management of boats, allowing the latter to be removed from the water and stored safely, or removed from storage and placed onto the water, as needed.

Abstract: The present invention relates to a rail intended to constitute a tread for heavy duty rolling stock, such as gantry cranes, mounted on wheels or rollers and concerns more specifically a guide rail on which both center-flange wheels or rollers, and lateral-flange wheels, as used on railway lines roll, comprising, in section, two integrally formed spaced heads running parallel to each other, the two heads having vertical inner side walls and being separated by a horizontal intermediate channel whose bottom constitutes a horizontal connecting strip.
