How to properly design gantry crane?
There are five points need to pay attention to about gantry crane
(1)The selection of a single girder gantry crane and double girder gantry crane
Usually, the weight is under 50 tons, span in 35 meters, the use of no special requirements, appropriate chooses single main types. If the door legs need wide width, high work efficiency, or often lifting heavy pieces, should use the double girder gantry crane.
(2)span and arm length
Gantry crane span crane is an important factor affecting its quality. In order to meet the demand of equipment selection, the conditions of use and span series standard, should try to reduce the span.
(3) The determination principle of wheel track
- Can meet the stability requirements of gantry crane track direction
- Dimension of goods can be smoothly through the legs of flat steel
- Pay attention to track B and S into a certain proportion, generally the tread B= (1/4? 1/6) S
(4) Determine the gantry crane span size
At work, gantry crane yard and external sizes of cargo and transport vehicles should leave some space size between channels, to facilitate loading and unloading operation. General transportation vehicles within the span of loading and unloading, and door shall be maintained legs more than 0.7 m spacing. There should be more than 0.5m spacing and transport vehicles when the spreader does not work. Goods more than one door legs, spacing should be more than 0.5 m.
(5) The selection of gantry crane electrical equipment
