Nowadays, China's construction machinery handsets are moving toward energy-saving, intelligent, large-scale direction, the first two needn't say much, now for almost all construction machinery enterprises, the first two are the development rules that must be followed. But the last one is different, it is not every construction machinery enterprise goal, of course, large-scale is not everyone can "play around", in a sense, large-scale is often meant to be more powerful strength, means the improvement of technology and adaptation conditions.

Throughout the development of construction machinery for more than a hundred years, more than 50 years ago, the size of which is similar to small agricultural machinery, and then slowly developed to the size of small and medium-sized automobiles, then appeared larger than the general automotive equipment, and then appeared crawler crane, a few stories of the giant.

In recent years, with the increasing number of large-scale and super-large-scale projects worldwide, such as large-scale infrastructure construction such as nuclear power plants and dams, as well as common construction machinery projects such as mines and large-scale buildings, in order to ensure the convenience and speed of construction, the demand has promoted the further large-scale of equipment, and the large-scale construction machinery has also become a result. As an important development trend.

It is noteworthy that the large-scale product is not simply the expansion of geometric series, such as the doubling of tonnage or other units of calculation, and its technical requirements are becoming higher and higher. Whether we can develop reliable and durable large-scale equipment has become an important indicator to measure the comprehensive strength of construction machinery enterprises.

Editors of China Construction Machinery Business Network noted that in recent years, the domestic construction machinery giants almost unanimously regard "large-scale" as an important direction of future development, for example, Xugong directly incorporated "large-scale" into the development strategy of the enterprise "three high and one big".

Believe everyone should know clearly crane, crane belongs to construction machinery, when using crane should know that crane is a lot of parts, crane is divided into cab, now there are many sales of crane cab in the market, then what is the development prospects of crane cab? Now let's have a brief look at it.

Overall, the international crane cab increasingly embodies the principles of ergonomics, toward safer, more comfortable, more reliable and more convenient to operate, more flexible, more beautiful appearance, more reasonable structure trend

Exhibition.

A number of high-level professional manufacturers have sprung up in the world to produce various cabs for the main engine of international construction machinery, such as French A nd rea s P titz, German W OE lfle and A o Sal, which provide crane cabs for world-famous enterprises such as Caterpillar and Liebherr.

The concept of crane cab assembly is becoming more and more perfect. The crane cab assembly for international production has been formed, including: cab structure assembly, electrical instrument assembly, control device assembly, seat, dashboard bracket assembly and comfortable and soft cab interior decoration and other international production system. The cab has formed an organic whole which is consistent with ergonomics.

The cab with multi-variety, multi-purpose, small and medium batch to meet the needs of various construction machinery products is one of the main characteristics of construction machinery cab. There are truck crane cab, loader series cab, roller series cab, excavator series cab, grader series cab, bulldozer series cab, dumper series cab, drilling rig series cab and crane cab for various purposes.

International Crane Cab upgrading and upgrading speed. For example, Liebherr's truck crane cab and control room from the original skeleton and cladding right angle, linear style, evolved into skeleton, small arc cladding, streamline arc style.

Modern technology and digital technology are widely used to produce crane cabs, forming a number of highly flexible manufacturing capacity of professional cab factories. Special-shaped seamless pipe, widely used numerical control bending machine bending forming process, forming a variety of good structural performance, and beautiful arc surface; sheet cutting and forming, widely used intelligent numerical control laser cutting machine blanking, numerical control stamping machine and numerical control bending machine molding manufacturing process;

The welding and welding of structural parts have been replaced by robots instead of manual welding.

The development trend of modeling style: 

the straight line and edge modeling style is still in use. For example, the Roller Cab of BMW, the Roller Cab of Caterpillar and the Roller Cab of Dana Parker. 

Streamline modeling style of arc and curved surface has been widely used in all kinds of construction machinery cabs, especially in all kinds of cabs produced by specialized factories. For example, Liebherr's large-tonnage truck crane cab has evolved from the original straight line, angular style to arc, curved surface streamline style. Give people a sense of fluency, nature and beauty. 

Streamline modeling of arc and curved surface is still used in the cab of excavator, which is becoming more and more exquisite, smooth and natural. 5 the use of large area, large field of vision and light colored glass has become the trend of development.
