What are the different types of gantry cranes?

Let me tell you the classification method of gantry crane. I hope it can help you,

What are the classifications of gantry cranes?

1. The double-girder gantry crane is a large-tonnage and commonly used crane equipment. The upper beam box of the double-girder gantry crane is equipped with a hoist hoisting weight, and is also equipped with an electric hoist auxiliary hook.

2. The upper bag and lower flower gantry crane is a gantry crane product that combines the flower frame structure and the box structure. The upper bag and the lower flower mean that the upper bag box beam (the steel plate is spliced ​​into a box beam) and the lower flower frame legs (angle iron) Welded into flower stand legs), there is also a kind of gantry crane with upper flower and lower package. The meaning of upper flower and lower package is the upper flower stand beam (angle iron is spliced ​​into a crane beam), and the lower box leg (steel plate welded into a box) leg).

3. The single main girder hook gantry crane involves the technical field of lifting equipment, and is characterized by including electrical equipment, trolley, crane operating mechanism, cable roller, platform track collision head, main beam, ladder, rigid outrigger, control room , Lower beam, flexible outriggers. The upper rigid cantilever beam and the flexible cantilever beam are arranged on the main beam, and the crane operating mechanism is arranged on the lower upper beam, the lower beam is arranged on the lower rigid leg and the flexible leg, the tram is arranged on the main beam, and the cable drum is arranged at one end The main beam and rigid legs, the rail collision head of the walking platform is mainly arranged on the last beam, the ladder platform is arranged on the rigid legs, and the upper part of the ladder platform is connected with the control room, and the control room is set on the lower side of the main beam. The patented technical structure of the present invention is simple and reasonable, convenient to use, convenient to install and maintain, and high in safety.

4. The European single-girder gantry crane lists the basic standard cranes commonly used, the standard span when the working class is A5 (FEM 2m), and the indoor crane without auxiliary hook. Customers can put forward corresponding requirements according to their needs.

5.The European-style double-girder gantry crane has the advantages of light weight, compact structure and low energy consumption. A trolley and a lifting arrangement are arranged on the bridge frame. The trolley can run forward and backward, and the cart can run and other arrangements to realize the transportation of materials and objects in a three-dimensional space. , European cranes adopt a unique planning concept, featuring small size, light weight and small wheel pressure. Compared with traditional cranes, the limit distance from the hook to the wall is the smallest, and the clearance height is the lowest. Keli cranes can work closer to the front and have a higher lifting height, which actually increases the useful working space of the existing workshop.

What are the application methods?

1. For general gantry cranes, box-type and bent-frame structures are often used, which are widely used. It can transport all kinds of raw materials in whole pieces and lumps. Generally, the door crane uses the gate hoist method to work at a higher level. The key to the general door crane is the lifting hook, the gate hoist, the electromagnetic induction, the reed crane, and also the semi-hoist.

2. Hydroelectric gantry cranes are mainly used for hoisting, opening and closing water gates, and also for installation work. The lifting capacity is 80~500 tons, and the span is small, which can reach 8~16 meters; the lifting time is low, which is 1~5 m/min. Although this type of lifting equipment cannot be hoisted frequently, the amount of labor after application is very large, so the work level should be appropriately improved.

3. Shipbuilding gantry cranes are used to assemble ship hulls. Generally, there are two cranes: one has two main hooks, which operate along the guide rails of the flange plate on the bridge frame; the other has a main hook and an auxiliary hook , operates on the guide rails of the lower wall beam of the cable tray to rotate and raise the large and medium-sized ship hull by section. Generally, hoisting 100~1500 tons, the span can reach 185 meters, the lifting speed is 2~15 m/min, and there is also a shaft speed of 0.1~0.5 m/min.

4. Shipping contenedor de grúas de pórtico for port terminals. The tow truck transports the cargo boxes unloaded from the ship by the quay wall shipping container transport bridge to the stacking yard or later, and then stacks or immediately loads and transports the cargo with the shipping container gantry crane, which can speed up the container shipping bridge or other lifting equipment. capital turnover. It can stack 3~4 layers and 6 rows wide container yard, generally using crawler type or rail train type. The van gantry crane is relatively straddle-type shipping container lifting equipment, and its span and relative heights on both sides are relatively large. This lifting equipment is suitable for the transportation of port logistics and has a higher working level. The hoisting rate is 8~10m/s; the span is determined by the number of shipping containers that need to be surpassed, and cannot exceed 60 meters, while the hoisting weights of 20-inch, 30-inch, and 40-inch long shipping containers are 20 tons, 25 tons and 30 tons.
