Single Girder Trussed Gantry Crane For Outdoors
Gantry crane is a variant of bridge crane, also known as gantry crane. It is mainly used for the loading and unloading of outdoor cargo yards, stockyards and bulk cargoes. Its metal structure is like a door-shaped frame, and two feet are installed under the bearing main beam, which can walk directly on the track on the ground, and the two ends of the main beam can have outrigger cantilevers. Gantry cranes have the characteristics of high site utilization, large operating range, wide adaptability and strong versatility, and are widely used in port cargo yards.
Gantry cranes can be classified according to the structure of the door frame, the form of the main beam, the structure of the main beam, and the form of use.
door frame structure;
Divided into gantry crane and cantilever gantry crane
Gantry crane:
1. Full gantry crane: the main beam has no overhang, and the trolley is carried within the main span;
2. Semi-gantry crane: The outrigger has a height difference, which can be determined according to the civil engineering requirements of the site.
Cantilever Gantry Crane:
1. Double cantilever gantry crane: a common structural form, the force of the structure and the effective use of the site area are reasonable.
2. Single cantilever gantry crane: This structural form is often selected due to site constraints.
Main beam structure
1. Truss type (MHh flower frame type)
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. Suitable for venues with low safety requirements and small lifting capacity
2. Box beam type (MH box type)
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 large tonnage gantry cranes, the main beam adopts box girder structure. Box girder also has the disadvantages of high cost, heavy self-weight and poor wind resistance.
Noted: The power supply mode of the gantry crane is mainly divided into two types: sliding contact line and cable reel. Since the crane supports customized products,the sliding contact line form is recommended for this type crane, and the conductive form and position should be specified when ordering.

| Outrigger shape |
Outriggers are inclined |
Outriggers are vertical |
| Saddle |
The outriggers of the A-type gantry crane with cantilever are inclined inward, which produces an inward horizontal force. Therefore, in order to prevent the inward deformation of the outriggers and cause the deformation of the entire gantry, the entire saddle should be set. The function is to bear the force to prevent the deformation of the gantry. |
Without saddles. |
| Outrigger space |
Its outrigger space is smaller than that of a U-shaped crane. |
The U-shaped gantry crane has a lot of leg space and can handle oversized objects. |
| Cost |
The distance between the two main beams of the A-shaped gantry crane is relatively small, and the size of the trolley is small, so the cost is relatively low. |
The distance between the two main beams of the U-shaped gantry crane is large, and the size of the trolley is large. It is used to lift large-sized objects over the legs, and the cost is relatively high. |
