Condition of large hoisting equipment

Condition of large hoisting equipment, marks a national engineering machinery manufacturing ability, determine the traffic construction speed and quality. Our country really started to manufacture large chainb lock machinery lifting equipment in the 70 s, after nearly 30 years of arduous exploration, has made great development. Large hoisting equipment level of design capability, manufacturing, lifting load and the intrinsic quality, mechanical properties and the contents of science and technology, continuously leapfrog development. At present, is moving toward product seriation, variety diversification, simple operation, intelligent operation and performance of modern direction. $$in recent years, our country developed manual hoist developed large hoisting equipment, and identified by authority department has been close to or reached the current international advanced level. And initially formed the development of generation, research generation, reserve generation of production pattern. Based $$$$from scratch to lay looking back the development course we may see that the first 20 years since the founding of new China, our country because do not have the ability to create large lifting equipment, lead to transportation and engineering infrastructure used imports all large lifting equipment. $$in the next few years, our country successfully developed the 38 meters high, weight of 140 tons, the hoisting with 10 tons of port portal crane M10-25 type. Used for lifting heavy weights, traction weight and tensioning of the SuoSheng, suitable for places no power supply and liquidity operations.
