Improved carriage for selectively engaging and disengaging a load for transporting same from one location to another such that the carriage upon full engagement with the load is positively coupled thereto for effecting its transport with minimal risk. To this end, the carriage is advantageously made up of a pair of guide blocks, a pair of actuating rods and a biased pivotally mounted pawl. Each actuating rod is biasingly mounted in its associated guide block. All of the aforementioned elements on the carriage cooperate with a pair of recessed guide plates and an upstanding lug as affixed to any load to be transported. Once the carriage is fully engaged with any load, resilient pads are provided on the carriage to assure positive coupling engagement between the engaged load and the carriage. After transporting any coupled load, the load is also provided with a pair of sliding rods for initially engaging the base or support to which the load has been transported. Then, the pair of sliding rods also engage the pair of actuating rods so as to effect disengagement of the pawl from the lug thereby releasing the carriage with positive engagement from the transported load and permitting full disengagement of the carriage from the transported load. One of the advantages of the improved carriage is that it permits not only remote initial and positive engagement of any load to be transported but also remote disengagement of the carriage from any transported load. Moreover, positive coupling engagement between the carriage and the load assures positive transport of the load in suspended balanced fashion with minimal risks even though the load in being suspendingly transported is maneuvered; and thus subject to longitudinal, transverse and rotary movements or any combination thereof.
