The crane runway beam is a structural component that supports the movement of an overhead crane. Crane rails are installed on these beams, allowing cranes to travel back and forth along the tracks. To ensure stability when lifting heavy loads, stiffening plates are welded onto the web of the crane beam for reinforcement.

In crane rail system construction, the crane runway beam serves as a critical track-bearing base. It plays a key role in determining the track installation method. Various rail-fixing techniques can be used on crane beams, including welding flat steel rails, securing lifting rails with hook bolts, or fastening rails with rail clamps.

Typically, bolt-type rail clamps are used on crane beams, requiring only pre-drilled bolt holes during beam processing. High-strength bolts are then used to secure the rail clamps in place. In special cases where welded rail clamps are necessary, the base of the welded rail clamp must be attached to the top of the beam during fabrication. Afterward, an anti-corrosion coating is applied to protect the welded seams from rust and corrosion, thereby extending the beam’s service life, minimizing on-site modifications, and reducing overall project costs.
