Gantry crane is a variant of the bridge crane

Electric gantry crane  is a variation of the bridge crane, gantry crane known. Mainly used for outdoor yard, yard goods, bulk cargo loading and unloading operations. Its metal structure shaped like a door frame, carrying the main beam install two feet down, you can walk directly to the track on the ground, both ends of the main beam may have overhanging cantilever. Gantry crane with a high utilization of space, large operating range, wide adaptation, versatility, etc., are widely used in the port yard.

Press the door in the form of the structure, according to the main form of beams, according to the main beam structure, according to use in the form of classification.Simple  single girder gantry crane  structure, easy manufacture and installation, small quality of their main beam much for the partial rail box-shaped frame structure. Compared with the double girder gantry crane, the overall stiffness weaker. Therefore, when the starting weight Q≤50t, when the span S≤35m, can this form. Single girder gantry crane doors leg has L and C forms. L type of manufacture and installation convenience, the force was better, the smaller their own quality, but, lifting goods through space at the relatively small number of legs. C-type legs made of sloped or curved shape, aimed at a greater horizontal space, so that goods pass foot.

Our companies need to increase efforts to implement the crane independent innovation strategy

 New Army of China's machinery and equipment industry, to seek progress as the column mounted jib crane industry guidelines, meanwhile, intensify the implementation of independent innovation strategy, merger integration of domestic and foreign technology, products, brands and other resources to enhance the capability of independent innovation .
Going cross-border mergers and acquisitions, acquire overseas mature technology, advanced production equipment, and even the technical and executive talent, domestic brands can waste handling crane machinery manufacturing enterprises effective resource input, speed up the pace to catch up with global brands.
Although in recent years the development of the domestic industry's key components is relatively fast, but many companies are still willing to rely on overhead cranes imported components to enhance the competitiveness of its products by the price to attract customers.
Completely on their own brands, although independent research can provide long-term development of the cornerstone of the bridge crane business, but the cost in terms of finance, time is too expensive, but also in the technical competition will be lagging behind. If there is a suitable acquisition targets overseas, and was acquired their own development objectives and has a high degree of strategic fit, then you should try its own brand overseas acquisitions.

Our lifting machinery industry out of a self-innovation, scientific development of the road

Through years of development, China's machinery industry out of a lifting innovation and scientific development of the road, in the gradual growth in showing a good momentum of development. From a global point of view of construction machinery sales, electric magnetic overhead crane occupied a share of almost 40%, while China's market sales accounted for 60% of global crane crane sales.
    From the appearance, the machinery industry's decline in recent years because of weak demand, overcapacity; but this is only the surface of the reason, deeper, and more reason is the nature of the stage of economic development, China has undergone profound changes, but the single-girder industrial overhead cranes industry development model has failed to change the attendant.
    2014 just past, although not yet released annual reports of major companies, but the first three quarters of performance, engineering machinery overhead crane industry seems "winter" still.
    Currently, the product is converted to mechanical versatility to the system integration technology, a single function from a single technology; product specifications from large to micro and small and medium-oriented extension: Twelve Five "period, high-end equipment products will be nurturing and development of machinery industry strategic focus areas.

Bridge crane manufacturing industry gradually transferred to multinational

 With the trend of economic globalization, more and more obvious, bridge crane manufacturing industry gradually shift to multinational corporations, our crane has become a foreign and private capital procurement more obvious, continue to support our mill industry. International grab bridge crane future market prospects are still a lot of room for development, but also face greater challenges.
At present, China's bridge lifting machinery industry, there is a big gap in the production of high value-added products, quality, variety and specifications, while the developed countries in the new industry, new equipment, new technology development and engineering primitive aspects the level of a certain distance, and the high energy consumption of China's enterprises, need to be improved in terms of environmental protection.
Application Grab overhead crane equipment expanding field has been applied more and higher requirements to shape the development of the fast pace of development in other manufacturing industries, has become a universal law, create demand in the world market.
Advanced technology is an important factor in the development of bridge crane business, experts believe that companies want to come to the fore, it is necessary to market demand and self-oriented development strategy, adjustment mode, looking for new opportunities to improve their scientific and technological content.

Insiders thematic analysis for your bridge crane hoisting phenomenon

The reason wall mount jib crane hoisting phenomenon occurred:
1, the working process, we do not rule out the presence of staff negligence, since bridge gantry crane hook is run by pulling the handle to pull the controller
Lead, so if the driver accidentally during work operations, did not pull the handle controller zero will cause the hook to continue to rise, causing things
It.
2, limit switch, column jib crane hook stopper is on the rise and fall of the process, is responsible for controlling the operation of the main bridge crane hook accessories, if we in the normal course of their work, check for stopper not careful enough, then the joint is very adhesions may occur, but once the joint adhesion limit, and that limit is equivalent to fail, leading to the main hook on the rise in the process, continue to rise, making the rope can not stand the pressure The collision, direct rupture, hook destroyed the goods happen to fall, resulting in unnecessary life safety issues.
3, because the longer the use of cranes age, and the staff did not work in the course of their regular inspection and maintenance, so that the stopper hidden loss
Spirit of risks, and finally cause hoisting phenomenon.

Overhead crane industry development constraints point

grabbing cranes industry development in energy dissipation process but there are people in the industry are not aware of the invisible killer. From the industry perspective, these invisible killers factors also severely restricted the development of the industry to a healthy direction.
As the domestic scientific and technological research in the past for lack of investment, has seriously affected the development of the overhead crane industry today due to technological level is lagging behind and cause behind the severe overcapacity situation. Beginning last year, the development of domestic crane industry has been in decline stage, but also the capacity development model to today's energy dissipation for enterprise development priority from the expansion of the high-speed stage.
Part of the grab bucket crane business in order to be able to further promote digestion and backward production capacity, has taken some irrational promotions, both take aggressive credit sales model: low down payment or even zero down payment way to pursue more orders, but these aggressive promotional methods There is undoubtedly a huge risk in the development process will give enterprises. Some users even in a crisis can not afford to repay the debt, eventually leading to the risk of the enterprise is difficult to recover the balance due.
This factor will have a direct impact on production and operations Magnetic overhead crane, etc., may result in more severe cases, the business capital chain breakage. This aggressive promotions, companies do not realize that the latter will become invisible killer enterprise development, although on the face of business is to get a large order, but it risks seriously affected the normal operation of the enterprise.

To develop scientific and technological innovation is the way out of the crane industry

If China's SMEs can also rely climax hold nation-building to develop their own, those large and very large Chinese construction machinery enterprises in order to ultimately foundry crane standing on top of the world engineering machinery, we must come to this level of business learning.
Current technology industry's largest gap with the developed countries is the technology of intelligent wall traveling Jib crane elements, in order to keep pace with the world, China, and even come to the forefront, it is necessary to develop the scientific and technological innovation, and actively participate in international competition and cooperation, and gradually the foreign core technology to thoroughly understand and master innovation.
