Gantry Crane Main Beam Type

Mar 14, 2017
1. Truss beam Gantry Crane
The Truss Gantry Crane main beam is welded angle or I-beam steel, this gantry crane advantages include low cost, light weight, good wind resistance. But, Truss beam has more welding points than Box beam, the truss gantry crane also have the defects of large deflection, low rigidity, relative low reliability, so truss gantry crane need frequent detection of solder joints, suitable for the lower safety requirements, smaller lifting weight.


 
2. Box Beam Gantry Crane
The Gantry Crane Box shape Beams are steel welded into a box structure, high security, high stiffness and so on. Generally used for large tonnage and oversized tonnage gantry cranes. Such as MG1200, the gantry crane lifting weight is up to 1200 tons. And, the box girder gantry crane is high cost, large dead weight, poor wind resistance and other shortcomings.


 
3. Honeycomb beam
This type beam is patented product, so fewer manufacturers. The honeycomb beam absorbs the characteristics of the truss beam and box girder, and larger rigidity, smaller deflection and higher reliability than truss type gantry crane, And, due to steel plate welding, self-weight and cost slightly higher than the truss, suitable for the frequent or heavy duty.
