Abstract: A system structured to transport a load carrying structure along the vertical direction while maintaining a substantially horizontal orientation thereof. A lifting assembly includes at least one lifting devices movably connected to the load carrying structure via a corresponding hoist line. The lifting device is configured to control the hoist line to accomplish raising or lowering of the load caring structure. A detection assembly, including at least one inclinometer determines an angle of inclination of the load carrying structure during the vertical travel thereof. A control assembly is operatively associated with the lifting assembly and the detection assembly to adjust the operative speed of the lifting device and length of the hoisting line upon a determination of an angle of inclination of the load carrying structure deviating from a predetermined angle of inclination indicative of a level orientation of the load carrying structure.
