Many interior generator rooms have very low headroom for performing maintenance and repairs on large gen-pack units. Rooftops also have heavy HVAC equipment that can be not only difficult to service but can also be hazardous for employees carrying lifting and handling equipment to the roof. The aluminum low profile gantry crane coupled with a V-Master floor crane can be the perfect solution. The V-Master is lightweight and can be disassembled for easy transport. The V-Master can then be used to assemble the Low-Profile Aluminum Gantry Crane. Not only is this convenient, but only one or two people are needed to assemble the Gantry Crane utilizing this system. Rooftops often also have limited load limits per square inch of load, this can be overcome by making a wider base for even weight distribution, or by simply making rails for the crane to travel on. If the equipment is to be left outside it can be finished with a variety of coatings.
