Abstract
With fast developments of the modern technology,the expansion of industrial production and the growth of the automatic level,applications of the carnes in the modern manufacture has been more and more extensive,the effect has been bigger and bigger. Higher and higher requirement has been caused. Especially,with the broad application of computer technology and the appearance of the advanced design method of a lot of interdiscipline,which urge the technology of the carne into a brand-new seedtime.
This crane is a 15t bridge crane. The main issue is the main crane hoisting mechanism for the overall design. According to the main parameters of the starting weight and the working environment calculate and select the appropriate wire rope, pulley and hook configuration group,design reel type then checking and calculated main dimensions,according to the work of lifting the speed and intensity of such factors as select and check the appropriate motor, reducer and brake.
This text briefly introduce the carne’s capability,structure,the actuality of development,and so on,referring to “Design criterion of carne” (GB3811-83) and design and calculate of the hoisting mechanism and its accessory in “Design handbook of carne”. From scheme demonstrating to designing and calculating,it takes full advantage of the computer in the whole design to raise the quality of the design,cut the cycle of the design,improve the work efficiency.
