Three tons of electric gourd, span 10 meters need what type of steel to be girder
More than a ton of electric gourd, it is not allowed to use the steel to make girder, use the composite beam, the i-steel use 240.
The i-steel 25a-50b is ok. But in the middle, you can ask for steel structures, and they all have a way of doing it. Wei hua group co., LTD. Was founded in 1988, after 20 years of continuous efforts, has developed into a collection of hoisting machinery research and development, design, manufacture, sales, installation, service, import and export business for the integration of large enterprise groups. Formed a powerful comprehensive technology innovation system, mechanical processing, heat treatment, welding, assembling, testing measurement and packing shipments complete advanced production equipment and large-scale production capacity. The main products are bridge, gantry crane, port machinery, electric hoist, steel structure building and so on nine big series more than 200 varieties, widely used in machinery, metallurgy, electric power, railway, water conservancy, port and other industries. Nearly 30 provinces, municipalities and autonomous regions throughout the country has a set of marketing and services for the integration of business outlets, products are exported to Britain, Russia, central Asia, South Asia, Africa and other countries and regions.
G. The hook should be flexible in horizontal and vertical direction. The pulley should be flexible. I. Steel wire rope should not be clearly cracked, and lined up on the drum, no loose pulley groove, twist, buckle, etc., and the lubrication is good. There is no abnormality in the crane. K. electric hoist working environment temperature is 25 ~ + 40 ℃ L. electric hoist is not applicable to full of corrosive gas or relative humidity is more than 85% of the place, not a substitute for explosion-proof hoist, unfavorable lifting molten metal or toxic, flammable and explosive. (2) the electric gourd shall not be suspended from the side, and shall be prohibited from overloading.
More than a ton of electric gourd is not allowed to make beams with steel, use composite beams, and steel and steel is used for 240. Electric hoist is a kind of special lifting equipment, installed on the crane, gantry crane, electric hoist has small volume, light weight, simple operation, convenient use, etc, used in industrial and mining enterprises, storage terminals and other places. considerations (1) before using the inspection A. there should be no obstacles and flotsam on the path of the operator's walk, line of sight and weight. B. Hand control button up and down, the right and left direction should be accurate, the motor and the reducer should not sound abnormal. The brake should be sensitive and reliable. D. Electric gourds should have no foreign body in orbit. The action of the upper and lower limit should be accurate. F. Hook stop nut should be set firmly.
