A mobile gantry is a versatile overhead lifting structure supported by wheeled legs, designed to be relocated across a facility's floor wherever lifting is required. Unlike fixed gantry cranes that are bolted to foundations, the mobile gantry eliminates the need for permanent installation, making it the ideal solution for rental shops, temporary job sites, and facilities where lifting needs shift between different workstations. The mobile gantry consists of one or two main beams (single-girder for capacities up to approximately 10 tons, double-girder for heavier applications), supported by A-frame legs mounted on heavy-duty locking casters. The lifting mechanism, typically a trolley-mounted electric or manual hoist, travels along the length of the beam, providing complete coverage of the work area beneath the crane. Mobile gantry cranes are available in load capacities ranging from 0.5 tons for light maintenance tasks up to 100 tons or more for heavy industrial applications at ports and steel mills. The beam is typically constructed from welded steel box sections or I-beams, with flange connections at cutting points to allow for modular assembly and disassembly. In an automotive assembly plant, mobile gantries are used to transfer engines, transmissions, and chassis components between production stations, moving along the assembly line as vehicles progress. The ground traveling can be manual human push for lighter units or electrically motor-driven for heavier configurations where manual effort would be excessive. The mobile gantry can be equipped with remote control for operator safety, allowing the crane to be operated from a distance during critical lifts. For outdoor applications such as shipping container handling or construction site material storage, weather-resistant coatings and larger-diameter wheels are specified.
