Abstract
A trailer for transporting, launching and retrieving floating box caissons includes a conventional road chassis, a tip-frame pivoted to the rear end of the road chassis and provided with a system for tipping the tip-frame from a normal horizontal position, and a sub-frame slidably mounted in the tip-frame and provided with a system for causing longitudinal translation of the sub-frame in relation to the tip-frame. A hauling carriage is guided for movement within the sliding sub-frame. A system is provided for moving the hauling carriage in translation within the sliding sub-frame. A lock is mounted on the hauling carriage for rigidly coupling a floating box-caisson to the carriage.
