Choose the gantry crane for business
First, the gantry crane selection
It is consistent with the relevant provisions of General gantry cranes GB / T14406-1993 and GB5905-86's.
Under normal circumstances, from the weight of the 50t or less, in the span of less than 35m, no special requirements, the choice of a single main beam. If you require door legs wide, high operating speed, or frequently lifting heavy parts, grew up pieces, then selected double girder gantry crane.
Second, the span and cantilever length
Gantry crane span is an important factor in their quality. Under the conditions of use and meet the equipment Subject to span series of standards, should minimize span.
Third, to determine the principles of Tread
(A) To meet the requirements of stability of the crane gantry along the track direction;
(B) Dimensions of the cargo to be able to pass the legs flat steel;
(C) Pay attention to the tread B and span S proportional relationships, and generally Tread B = (1 / 4-1 / 6) S.
Fourth, the gantry crane pitch size determination
In operation, the door should be left between the external dimensions and yard cranes and cargo space transportation vehicle passages a certain size in order to facilitate loading and unloading operations. When the general transport vehicle loading and unloading in the span, and the door should be kept above the legs have 0.7m spacing. Spreader should not work in more than 0.5m spacing and transport vehicles, cargo leg when met; there should be more than 0.5m spacing.
