Gantry Cranes
Gantry cranes are customizable for a variety of applications and service requirements.
At G.W. Becker, Inc. our gantry cranes are designed and manufactured to either CMAA Specifications or AIST Technical Report #6. In addition, they meet current ANSI, NEC, and OSHA specifications.
Gantry cranes are available in either semi-gantry (single leg) or standard gantry (double leg) configuration, and are available in single girder or double girder arrangement.
Ordinary girder type construction for light duty, short span bridges are standard rolled steel sections. Alternatively, welded plate box girders are available, but standard on heavier duty, higher capacity and longer spans.
Gantry cranes are customizable for a variety of applications and service requirements. They are typically utilized as workstation units below primary overhead cranes within an aisle; as independent units eliminating a costly runway structure, where a runway would be an obstruction to material flow within the plant, added to a facility without an existing runway or as a freestanding unit where a building does not exist.
Benefits of Gantry Cranes
No Runway Required
Gantry cranes operate independently of building structure, making them ideal for facilities without existing runways or areas where columns would obstruct workflow.
Flexible Installation
Use indoors or outdoors, below existing cranes, or in locations where overhead systems cannot be supported.
Cost-Effective for Localized Work
Great for assembly, maintenance, fabrication, and material transfer without modifying the building.
Built for Any Duty Level
Engineered to meet CMAA duty classifications based on application needs.
Common Applications
Workstations & Production Cells
Welding bays, machining centers, repair areas, and light assembly zones.
Facilities Without Structural Support
New buildings, expansions, or outdoor sites lacking adequate overhead steel.
Outdoor Handling
Shipyards, rail yards, steel yards, and construction or precast operations.
Supplemental Lifting
Adds capacity under primary overhead cranes for smaller, repetitive lifts.
