Portal Crane (also known as gantry crane) is a kind of gantry crane which is supported by two legs on the ground.Some gantry cranes only have a leg on one side and a leg on the other side running on the workshop or trestle bridge.In order to enlarge the crane operation range, the main girder can extend out the legs to one or both sides, forming a cantilever.
