Heavy hauling system with hydraulic-powered extendable axles

A trailer, comprising:

• at least one carriage, wherein the at least one carriage comprises:
• a central beam extending the length of the at least one carriage;
• a plurality of hollow cross beams coupled perpendicularly to the central beam, wherein each cross beam comprises at least one slidable beam positioned within the cross beam, wherein the at least one slidable beam is coupled to at least one axle;
• and
• a hydraulic system coupled to each of the plurality of cross beams for hydraulically sliding the at least one slidable beam positioned within each cross beam,
• wherein:
• the hydraulic system hydraulically slides each slidable beam positioned within each cross beam away from or towards the central beam to vary carriage width;
• the hydraulic system hydraulically slides each slidable beam positioned within each cross beam away from and towards the central beam in unison such that carriage width is uniform during and after sliding of each slidable beam;
• and
• the hydraulic system further comprises a hydraulic line coupled to the central beam on one end and the slidable beam on the other end, wherein the hydraulic line extends or contracts when the slidable beam slides within the cross beam.

A vehicle for transporting loads, comprising:

• a truck for providing locomotion;
• and
• a trailer coupled to the truck via connecting means, the trailer comprising at least one carriage, wherein the at least one carriage comprises:
• a central beam extending the length of the carriage;
• a plurality of rectangular-shaped slidable beams coupled perpendicularly to the central beam, wherein each slidable beam is coupled to at least one axle;
• and
• a hydraulic system coupled to each of the plurality of slidable beams for hydraulically sliding each slidable beam so as to vary the width of the carriage,
• wherein the hydraulic system hydraulically slides each slidable beam away from or towards the central beam, and
• wherein the hydraulic system further comprises a hydraulic line coupled to the central beam on one end and a slidable beam on the other end, wherein the hydraulic line extends or contracts when the slidable beam slides.
