coupling hook
1.Problems in using screw-crane in fields and water resources engineering were analysed with examples of engineering project.Based on this,a method was presented.By using double-hook screw-crane and connecting two screw-cranes by an intermediate bearing and a gear coupling,the problem of inefficiency in door-closing was solved.The double-hook screw-crane could work synchronously.
2.Sets of assembly hook with the hoisting capacity from 3.2 tons to 300 tons,assembly weel,type Φ250-900,and shaft coupling prodaced by this company are widely used in varieties of hoisting ,metallurgy,oilfield,harbor,constuction and other industries.All kinds of non-standard assembly hook,shaft coupling and othe settings of machinery also can be designed and produced according to the requirements of customers.Sincerely welcome the friends at all circles to the company for visiting,guiding and business.
