초록

A straddle crane including four vertical column members, two side beam or torsion members, and at least one header beam member, and having wheel or caster assemblies supporting each vertical column member. The straddle crane is implemented for two-wheel or four-wheel steering and for two-wheel or four-wheel driving with open or closed ends. The structures of the header beam and the side beam members are appropriately selected, and the attachment means therefor to the vertical column members are chosen to accommodate the various forces and stresses occurr...
