Unlike bridge cranes, which are connected to a building’s support structure, gantry cranes are freestanding systems that lift and move objects independently, without the need for permanent runways and columns. Their self-sufficient design makes them well-suited to both indoor and outdoor settings.
While large gantry cranes move along a rail system, smaller ones are fully mobile. Instead of moving back and forth over a fixed area, they travel on wheels or casters, making them a versatile solution for operations that need to transfer loads quickly between workstations, loading docks, production lines, and storage areas.
Ready to Improve Your Lifting Capacity?
Gantry Cranes We Manufacture
Gantry cranes are available in a wide range of sizes and configurations, enabling them to meet practically any lifting requirement. Depending on your application, you may require a:
Full Gantry Cranes
Full gantry cranes consist of a bridge beam supported on either side by a set of vertical legs that run on rails embedded in the ground or wheels that run directly on the floor. Built for heavy loads, these cranes work well outdoors but are sometimes installed in buildings without the infrastructure necessary for a traditional overhead system.
Semi-Gantry Cranes
Semi-gantry cranes combine features of overhead cranes and full gantry cranes. Instead of being supported by vertical legs on both sides, the bridge is supported by legs on one side and an elevated runway on the other. Because they use less steel and fewer rails, these cranes have a smaller footprint while still providing coverage for large, open areas.
Fixed Gantry Cranes
Fixed gantry cranes are supported by freestanding legs bolted to the ground. Rather than traveling back and forth on rails or wheels, they’re designed to move objects within a small, well-defined area. Strong, stable, and easy to maintain, they deliver heavy lifting capacity in facilities where structural modifications are impractical.
Portable Gantry Cranes
Portable gantry cranes are designed to be mobile, compact, and lightweight. Unlike other gantry cranes, portable gantry cranes do not require fixed structures such as rails or runways. They can be repositioned as needed to lift objects at individual workstations or transfer loads between assembly and storage areas.
Single Girder Gantry Cranes
Designed for light-to-medium loads, single-girder gantry cranes consist of a single bridge beam suspended between two vertical legs that travel on wheels or ground-level tracks. The simple structural design allows for straightforward setup and maintenance, making this an affordable option for workshops, warehouses, and material yards.
Double-Girder Gantry Cranes
Built for heavy-duty lifting, double-girder gantry cranes consist of two parallel beams, which create a stronger, more robust structure capable of handling difficult loads over long distances. The hoist and trolley travel on top or between the girders rather than underneath, providing additional lift height compared to single-girder cranes.
Adjustable Height Gantry Cranes
A popular choice for locations that need a single crane for multiple tasks, adjustable height cranes let you raise and lower the center beam in order to optimize the unit for different loads. Suitable for lightweight applications, adjustable height cranes can also be reconfigured to fit through doorways, under ceilings, and around equipment.
Gantry Crane Benefits
While gantry cranes are a practical choice for operations that can’t accommodate a traditional overhead crane system, they also offer several advantages that make them a valuable long-term investment.
Versatility
Gantry cranes can be used in a wide range of applications: managing inventory, moving raw materials, vehicle assembly, and more. Their simple design and setup allow them to be used in both indoor and outdoor work environments, according to your needs.
Cost-Effectiveness
Because they use less material and don’t require extensive building modifications, gantry cranes are less expensive compared to overhead bridge cranes. At the same time, their ability to be relocated and reused in different areas often eliminates the need for multiple fixed cranes.
Space Efficiency
Gantry cranes are typically found in buildings that weren’t designed to carry crane loads, where ceiling clearance is limited, or where the lifting operations need to remain flexible. Their small footprint also ensures the floor below remains open to workers and vehicles.
Ease of Installation
Most gantry cranes are designed for quick installation and assembly. Their modular components require less preparation and can be brought online in a comparatively short time, while their precision controls are easy to operate, making them a useful addition to evolving work sites.
Enhanced Safety
Simmers engineers ensure every piece of field equipment they install comes with a full set of safety features such as overload protection, emergency stop functions, and precise control mechanisms to minimize the risk of accidents and mechanical damage.

FAQs
-
What is a gantry crane?
A gantry crane is a freestanding lifting system designed to move heavy loads without reliance on your building’s support structure.
-
What is the difference between a gantry crane and an overhead bridge crane?
Overhead bridge cranes are supported by columns and runways connected to the building’s framework. By contrast, gantry cranes are self-sufficient systems that don’t require any additional infrastructure.
-
What is the lifespan of a gantry crane?
If installed and maintained by a professional team, most gantry cranes last 15-30 years. However, their lifespan is affected by their operating environment. Harsh weather conditions and heavy duty cycles can significantly shorten your crane’s service life. Under these circumstances, proactive inspections and maintenance help you catch problems early and prevent unscheduled downtime.
-
How long does it take to get a custom gantry crane built?
A simple gantry crane can be purchased in as little as 4-6 weeks. Custom gantry cranes may take 12-18 months to complete from concept to finished product, depending on the crane’s span, capacity, height and complexity.
-
Can an existing gantry crane be modified to increase its lifting capacity?
Yes, but it requires a thorough evaluation of the beam, legs, joints, and wheels to ensure they’re capable of supporting the additional weight.
-
Can Simmers replace parts on a gantry crane from another manufacturer?
Yes, Simmers can obtain replacement parts for most units currently in use. Just send us the manufacturer’s name and the serial number of the part in question. If you’re not sure who made the part, send us a picture and a detailed description.
