Infographic: AT&F Crane Structural Fabrication

For years, AT&F has been a major presence in the heavy construction industry that specializes in manufacturing crane structures. View the infographic to learn about AT&F's dedication to crane boom fabrication:

Robotic Welding At AT&F

When AT&F was approached to produce 40ft long complex weldments for a crane manufacturer, the company looked to employ new technology on a larger scale than is typically attempted. AT&F is known for the scale, scope, and precision of our long-forming capabilities. More recently, we made investments to cover long length precision welding using robotics. Traditionally, long length full penetration welds are susceptible to heat distortion when performed manually, or by common semi-automatic methods.

Boom Welding Innovation - Using Hybrid Laser


The first modern mobile cranes appeared in the 1830’s and were able to lift their own weight. Through design innovation and advancement in high strength steel, cranes today are able to lift 10 times their own weight. New innovations are the result of advanced manufacturing technology. Submerged Arc Welding (SAW) has been the standard process used in the welded crane boom industry for decades. Although submerged arc welding is a proven and time tested method for fabricating booms, it leaves room for improvement.
