Upgrades That Improve Safety, Capacity, and Performance

Big G Steel provides structural and mechanical crane & runway modifications and complete equipment relocation services. Our work includes structurally and mechanically modifying overhead cranes, whether top-running single girder, top-running double girder, or any variation of under-running cranes.

Modifications can also involve relocating equipment, which may include dismantling, removing, and reassembling existing structures. During relocation, we can adjust system dimensions by lengthening or shortening crane girders and runway structures to meet new facility requirements.

In addition, we perform capacity upgrades by structurally enhancing crane runways with added steel members and reinforcements, as well as strengthening crane girders, end trucks, and other components. Hoist replacements and related upgrades ensure that your modified system is built to handle greater lifting capacity while maintaining the highest standards of safety and performance.

Safety Built Into Every Modification

From planning and placement to final load testing, our crews follow proven procedures and industry standards to protect your people and your facility throughout every crane & runway modification.

Proper alignment, structural integrity, and controlled lift practices ensure each modified system performs safely and reliably. All work is completed in accordance with OSHA, NFPA, and ASME/ANSI B30 standards—so your upgraded crane system is compliant, secure, and ready to perform under real production demands.
