Lifting equipment is a kind of space transportation equipment

Lifting equipment is a kind of overhead gantry crane transportation equipment, main function is to achieve the weight of displacement. It can reduce labor intensity, improve labor productivity. Hoisting machinery is an integral part of modern production, some of the hoisting machinery can also in the process of production for some special process operation, the production process to realize mechanization and automation. Lifting equipment to help mankind in conquering nature change nature of activities, to achieve the past large hoisting and moving objects cannot be achieved, such as heavy ship unit assembly, chemical reaction tower of integral lifting, sports venues the integral lifting of steel roof truss, etc. Use lifting machinery has a huge market demand and good economical efficiency, lifting machinery manufacturing industry has developed rapidly in recent years, the average annual growth of about 20%. Due to production process, from raw bridge gantry crane to products for material handling quantity often use hoisting and conveying machinery is the product of the weight of a few times, even hundreds of times.

To improve the national economy of hoisting machinery

Hoisting machinery sectors of the national economy to improve labor productivity, shortening production cycle and reduce production cost, should not be underestimated role, and therefore is widely used in various types of production enterprises. The pros and cons of hoisting machinery manufacturing quality and use of security technology condition quality directly bridge gantry crane the state property and the safety of life of the masses. In order to strengthen the safety supervision of special equipment, to prevent and reduce accidents, guarantee the people life and property safety, promote economic development, 373 decree of the state council has issued a "special equipment safety supervision regulations", made clear of overhead gantry crane equipment in the design, manufacture, installation, use, inspection, maintenance, renovation and other aspects of the safety supervision management. 

The crane system's work efficiency

The swing on the one hand, lowers the crane system's work efficiency, on the other hand may lead to load with the operator or other objects collide cause casualties or damage. Therefore, many scholars in view of the bridge crane control system for a overhead gantry crane amount of research work: on the one hand require car quickly and accurately reach the target location, on the other hand it also requires can effectively restrain the load swing. The most commonly used open-loop bridge crane control method is the Input Shaping (Input Shaping), but this bridge gantry crane of method for system parameter precision demand is higher, so more and more scholars closed-loop control is used to solve the problem of oscillation inhibition and car positioning. .

Simple electric hoist gantry crane is a crane

Simple electric hoist gantry crane is a crane, which has two kinds of single and double beam. Because of its simple structure, easy manufacture, light weight, low cost, easy installation and maintenance overhead gantry crane obtained the considerable development, widely used in industrial and mining enterprises, railways, docks, warehouses, material yard and other places. Because of electric hoist gantry crane structure is simple, however, in the design, production, installation, inspection process, such as failure to cause enough attention. In the electric hoist gantry crane in use process, if the defect of leg connections, such as fracture hidden danger of overturning bridge gantry crane occur. As a result, the examination link, pay attention to the electric hoist gantry crane leg installation quality inspection, is to ensure production safety, prevention of the accident is an important guarantee. Example: in 2010, the zhuhai YiMenShi inside some temporary steel structure workshop crane accident, at that time, the operators are preparing to lifting items, items in lifting has left the ground, the crane suddenly overall tilt to one side leg, fortunately, at that time the next workshop are not present in more than 20 workers, no casualties at the scene. Accident analysis accident lifting main parameter table 1 accident hoisting main parameter table type MH16-22 A5 rated lifting weight 16 t lifting speed 8 m/min lifting height of 6 m span 22 m working-level A5 cart speed 20 m/min.

Imported equipment characteristics and use of electrical equipment maintenance

The characteristics of the imported equipment electrical devices and the basic situation of imported equipment in operation and maintenance characteristics and basic situation in operation and maintenance of electrical devices TengBaoYu (liaoning at liaoning 122009) are introduced in this paper introduced the main characteristics of complete sets of overhead gantry crane electrical devices, problems found during the use and maintenance experience. The article points out that the advanced technology and equipment must have the corresponding staff, management system and accessories to ensure corresponding, to give full play to the introduction of device of high efficiency, high quality. overhead gantry crane trade from our factory in the UK Deng Lupu international engineering co., LTD., has introduced the production of 150000 sets of full load of steel wire radial tire production line, early in 1989 through the national acceptance. Since putting into production, from five years of operation, equipment and pipe is analyzed.the achieves a higher level, the scale of production to meet the design basic ability. Actual use prove that these imported equipment is advanced, operation is reliable. 1 the characteristics of the imported equipment electrical devices 1.1 reliable these imported equipment more than a dozen companies from six countries, mixer, vulcanizing machine, inspection and testing equipment, a total of more than 50 Taiwan (sets), all products for the mid - 80 - s, technically mature, driving scheme is reasonable, and has been used in some countries, therefore, to run the reliability is high. The quality of electrical device is stable, reliable, electrical components comply with IEC standard.
