Good Stability Double Girder Gantry Crane Strong Bearing Capacity




The double main girder gantry crane has strong bearing capacity, large span, good overall stability and many varieties, but its own quality is larger than that of the single main girder gantry crane with the same lifting capacity, and the cost is also higher. According to the structure of the main beam, it can be divided into two forms: box beam and truss. Generally, a box-shaped structure is used.


Main beam structure:

1. Truss beam
The structural form welded by angle steel or I-beam has the advantages of low cost, light weight and good wind resistance. However, due to the large number of welding points and the defects of the truss itself, the truss beam also has the disadvantages of large deflection, low rigidity, relatively low reliability, and frequent inspection of welding points. It is suitable for venues with low safety requirements and small lifting capacity.


2. Box girder
The steel plate is welded into a box-type structure, which has the characteristics of high safety and high rigidity. Generally used for large tonnage and super tonnage gantry cranes. Box girder also has the disadvantages of high cost, heavy self-weight and poor wind resistance.

How to choose:


1. Selection of gantry crane
Comply with the relevant regulations of GB/T14406-1993 and GB5905-86 for general gantry cranes.
Under normal circumstances, the lifting capacity is less than 50t, the span is less than 35m, and there are no special requirements for use, the single main beam type should be selected. If the width of the gantry leg is required to be large, the working speed is high, or the heavy and long pieces are often lifted, the double-girder gantry crane should be selected.


2. Span and cantilever length
The span of the gantry crane is an important factor affecting the quality of the crane itself. In the selection, the span should be minimized under the premise of meeting the equipment use conditions and meeting the span series standards.


3. The principle of determining the wheelbase
(a) It can meet the stability requirements of the gantry along the direction of the crane track;
(b) The overall dimensions of the goods should be able to smoothly pass through the flat steel frame of the outriggers;
(c) Note that the wheelbase B is proportional to the span S. Generally, the wheelbase B=(1/4-1/6)S.


4. The gantry crane spacing size is determined
During work, there should be a certain amount of space between the external dimensions of the gantry crane and the passage of goods and transport vehicles in the yard to facilitate loading and unloading operations. When loading and unloading within the span, the general transport vehicle should keep a distance of more than 0.7m from the door leg. When the spreader is not working, there should be a distance of more than 0.5m from the transport vehicle, and when the goods pass through the door legs, there should be a distance of more than 0.5m.



Double girder gantry crane is mainly used in Steel, Forest Products, Intermodal, Biomass/Pellet, Concrete warehouse, rail station, stock yard and shipyard, and many other industries.
