Optional gantry crane

Under normal circumstances gantry crane, 50t lifting capacity in less span of less than 35m, no special requirements, should use a single main beam. If the required width of the gate leg,Coil Bar and Plate Handling Cranes high working speed, or frequently lifting heavy parts, grew up pieces, you should choose double girder gantry crane. Gantry crane span is an important factor affecting their quality. Selection, to meet the conditions of use and premise equipment meets span series of standards, should be minimized span.
Tread determine the principles of
(A) to meet the requirements of the stability of the crane gantry along the track direction;
(B) cargo dimensions to be able to pass the legs flat steel;
(C) pay attention to the track B and span S proportional relationship, and generally track B = (1/4-1/6) S.
Sizing gantry crane spacing
At work, the door should be left between the external dimensions and yard cranes and cargo space transportation vehicle access certain size in order to facilitate loading and unloading operations.workshop gantry crane When loading and unloading transport vehicles generally within the span, the door should be kept with the legs have more than 0.7m spacing. Spreader should not work in more than 0.5m spacing and transport vehicles, cargo when the legs get married, there should be more than 0.5m spacing.
