As the utility model discloses a further improvement can be through increasing the extension guide rail with the unlimited extension of quantity of support post.

When the shore-based vehicle-mounted retractable crane of the underwater mechanical equipment is used, after the guide rail in the vehicle is installed, the guide rail in the vehicle penetrates into the lower part of the guide wheel of the small crane, and the small crane is fixed on the vehicle inner support frame by using the rope; after the fixation is finished, the extension guide rail is connected with the guide rail in the vehicle through threads; after the installation of the extension guide rails is completed, the lifting hook of the small crane is connected with the lifting ring of the auxiliary support upright post, the motor is started to lift the small crane, and the two guide rails are respectively installed on the two support upright posts.

The utility model has the advantages that: the extension guide rail, the limiting device, the small crane and the support upright post can be disassembled and assembled on site and carried along with a vehicle. The length of the extension guide rails and the height of the support columns can be customized according to the height and the length of the carriage, and the number of the extension guide rails and the number of the support columns can be manufactured according to the carrying distance. The applicability of the folding and unfolding crane is better improved.
