What is the difference between port cranes and ordinary cranes? Port crane is only relative to the general crane, the key difference is that the crane construction is relatively small, the electrical control system is relatively stable, for the design of the steel frame structure and domestic cranes are basically the same.
What is the difference between port cranes and ordinary cranes? Port crane is only relative to the general crane, the key difference is that the crane construction is relatively small, the electrical control system is relatively stable, for the design of the steel frame structure and domestic cranes are basically the same.
Port cranes, working level A6 above, the demand for office environment is mainly for the working conditions and operating regulations are very strict, for now, mainly used in airlines, vehicles, power engineering, chemical plants, smelters and other industries.
The height of the harbor crane is small, which can reduce the height of the crane plant; secondly, it is lighter in weight, which can reduce the cargo capacity of the plant; it can expand the operating space of the crane. The reducer of the harbor crane is selected as gear reducer, which can effectively enhance the service life of the whole equipment.
The running organization reducer of the harbor crane selects the hard tooth surface three-in-one reducer, which has a tight layout and stable operation. The calcined wheel set is selected and mechanically processed and milled for installation, with high assembly precision and sturdiness. Thick steel plate rollers are selected to improve the strength and service life of the rollers.
There are many types of cranes, and many different kinds of cranes are used in different places. European classical single girder overhead cranes and European beam overhead cranes are two relatively large crane types, in addition to the total number of two simple beams are different, there are many other differences, double like these cranes specific differences are?
A, the difference in office environment
Generally speaking, rigid cranes are generally suitable for short span, lifting lifting level is small, small space in the work area. Double girder overhead cranes are used for large spans, lifting lifting capacity, and large space in the workplace. Contrast with the two, the European classical rail cranes work a little more effective.
Second, the difference in the construction of the crane
Single girder overhead crane weight is relatively light, the structure is very simple, assembly, disassembly and maintenance is very simple, while the double girder overhead crane weight is a little heavier, the structure is more complex, assembly and disassembly and maintenance provisions are also higher.
Third, the difference in the cost of raw materials for rigid cranes and rail cranes.
Because the overall body of the single girder overhead crane is relatively small, raw material consumption is small, the cost of raw materials is not too high.
Fourth, the difference between the physical properties of rigid cranes and rail cranes.
Types of cranes: lifting machinery used in the bridge repair project, according to its construction and performance is not the same, generally can be divided into three categories of light and small lifting equipment, flat arm type lifting machinery and telescopic arm type cranes.
Light and small lifting equipment such as: hydraulic jacks, HuLu, cranes, etc. Cable bridge type cranes such as beam cranes, dragons cranes, etc. Telescopic boom type cranes such as mobile rotating cranes, vertical cranes, vehicle cranes, car tires, crawler cranes, etc. In a certain range of vertical lifting and level transport lifting objects have to multi-posture lifting machinery. Also known as a crane. Classified as material handling machinery. Crane work characteristics are to do intermittent movement, then in a work cycle on the material, stabilization seepage, unloading off and other actions of the relative organization is alternate work.
