Traveling gantry crane selection
First, the lifting capacity, such as 20T, 50T, or 100T, followed by the span and lifting height, the choice must be screened for performance, especially for those who often hoisting, the traveling gantry crane which often load the rated capacity or even overload, must have many problems.
The cantilever arm is usually not more than one-third of the main girder. If the special environment, the drawings need to be redesigned to avoid the danger, so does the one-sided cantilever gantry crane, that is pursues the balance of the traveling gantry crane.
Traveling gantry crane electrical equipment should comply with GB / T14406-1993 standards.
The track distance must meet the stability requirements of the gantry crane traveling along the track. Pay attention that the track distance B is proportional to the span S, generally B = (1 / 4-1 / 6) S.
