Overhead & Gantry Cranes

Ace World Companies designs and manufactures gantry cranes that provide safe, reliable lifting power in environments where overhead runways are not an option. Supported by upright legs traveling along ground-level rails, gantry cranes excel in outdoor operations, expansive yards, and facilities where structural supports cannot carry the weight of an overhead system. 

As one of the leading gantry crane manufacturers in the United States, Ace has decades of experience building both standard and custom gantry crane systems that perform under the toughest conditions.


Not every facility can support a full overhead bridge system. In those cases, overhead and gantry cranes provide the flexibility to keep materials moving without depending on roof structures or elevated runways. Rails embedded in concrete sit flush with the floor, letting forklifts, trucks, and other equipment cross without interruption. A hoist gantry solution blends seamlessly into the flow of an operation while adding heavy-duty lifting power where it’s needed most.

When customers turn to Ace, we walk through the full scope of requirements:

  • Choosing the right design: double-leg, semi gantry crane, or single-leg gantry crane.
  • Accounting for the environment: wind, saltwater, dust, or moisture that could affect performance.
  • Planning for extremes: motor heaters, specialized coatings, or protective covers when temperatures or conditions demand it.
  • Matching the power supply: ensuring electrical systems integrate cleanly into the facility.

Every design is supported by our decades of industrial crane expertise, ensuring your investment will operate safely, efficiently, and dependably for years to come.


Every worksite has its own demands. To meet them, Ace World Companies manufactures a range of gantry systems that adapt to different industries, building layouts, and lifting capacities. Whether you need a compact solution for limited space or a heavy-duty crane for shipbuilding, we provide designs that maximize efficiency.

Double-Leg Gantry Cranes

Built with two support legs traveling on ground rails, double-leg systems are widely used in shipyards, rail yards, and loading docks. These overhead gantry cranes can be customized with operator cabs, rotating hoists, and protective housings to withstand outdoor exposure. With capacities reaching into the hundreds of tons, they excel in large-scale fabrication and shipbuilding.

Semi Gantry Cranes

A semi gantry crane combines one support leg running along a ground rail with a bridge end supported by a building structure or elevated runway. This design frees up valuable bay space, making it ideal for warehouses, machining facilities, and production environments where part of the floor is needed for other operations.

Single-Leg Gantry Cranes

Also called one-leg systems, single-leg gantry cranes offer a hybrid approach: one side travels on a ground rail, while the other connects to an existing building structure. This design provides significant lifting power without requiring a full gantry footprint, making it a smart option for operations where space is at a premium.

Custom Gantry Cranes

Some environments demand more than standard equipment. Ace specializes in designing custom gantry crane systems for unique conditions, such as coastal shipyards with salt spray, fabrication plants handling irregularly shaped loads, or heavy industries requiring extreme capacities. Our engineers create solutions that match the precise span, capacity, and duty cycle your application requires.
