Gantry crane

ship gantry crane is a variant of the bridge gantry 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. It may be in the form of a door frame structure, according to the main form of beams, according to the main beam structure, according to use in the form of classification.

You know how much knowledge gantry cranes?

electric gantry crane lifting equipment belonging to one, commonly known as gantry cranes. Such cranes are mainly extract article by means lifted after then move horizontally to the destination lowered. Gantry crane is a do loop, intermittent movement of equipment, mainly by the main circuit, control circuit, lighting signal circuit and the like. Purchase of gantry cranes at the construction unit should be combined with the construction situation of enterprises: the frequency of a combination of factors, utilization, from the weight, etc. into account. In addition to considering the technical parameters, but also need to conduct market research to understand the manufacturer's reputation, technical level. Typically buy when the span gantry crane technical requirements, often starting weight of less than 50 tons, the span needs no special equipment to within 35 meters. If you need a large weight lifting, the need to use large span and double bridge gantry crane

. When the purchase of gantry cranes delivered to your door, it should be out of the box inspection, to check whether the information is complete, matching the parts for damage, whether complete and so on.

Crane, also known as crane

Gantry crane  refers to a range of vertical lifting and carrying heavy loads of horizontal multi-action lifting machinery. Also known as cable car. The main features of terrains are: its driving cab and crane cab combined, is evolved by the crawler crane (crawler), will track and walking part of the running gear bracket into the chassis has a tire to overcome disadvantage of crawler crane (crawler crane) track shoes on pavement damage, belonging to material handling machinery. Single girder gantry crane lifting equipment to do some work is characterized by intermittent exercise, namely a working cycle reclaimer, ship appropriate mechanism to transfer, unloading and other movements are working alternately, 

development and use of cranes on the market more widely. Gantry crane manufacturers  because they are not leg slings and hoists with often some accident, driving speeds are more cranes (crawler) fast; job stability, lifting large can be hoist walking within a specific range, but must ensure that road grading solid tire pressure to meet the requirements, hanging above the ground shall not exceed 50CM; ban with a load of walking long distances. To ensure the safety of operations, the current domestic basically prohibit the outriggers are not hoisting operations.

Gantry multi-use box type and truss structure

Santo gantry crane multi-use box type and truss structure, the most widely used. You can carry a variety of bulk materials into items and, from the weight of 100 tons, a span of 4 to 39 meters. Grab common with the work of a higher level gantry crane. Common gantry crane mainly refers hook, grab, electromagnetic, hoist gantry crane, also includes semi gantry crane .

Bridge divided into single and double-girder, single girder generally 10t or less span is relatively small. 10t double girder can be more, and even some large traffic can be done from the weight of hundreds of tons, the span can be made relatively large. Orbit bridge is usually installed on the rail beam, bearing rail rail mounting bracket on the plant or from the vertical column.Gantry crane rail mounting on the ground, on both sides of the main beam with vertical legs have driven device leg stand upright on the track.

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.
