As a company continuing to focus on customers’ needs and carrying out continuous innovation, Henan Yuntian Crane takes the lead in establishing the R&D Center for Crane Design compared with those in the same industry in China, attracts the top-class talents within the industry and has obtained more than 140 patents successively.
Based on introducing and absorbing the design philosophy and manufacturing technology of cranes domestically and overseas, the R&D Center strives to the modification and design of electric hoist, single girder and double girder cranes and launches new products successively, such as the new type crane, trolley (winch type), steel structure design and trolley (new type hoist), etc. (If necessary, the product feature will be performed and showed by pictures and subtitles) The Company also invests a large amount of money in the purchase of more than 1,300 sets (suits) of high-grade, precision and advanced equipments, introduces the weldless cover plate and the production line of one-time forming and slitting line of weldless U-groove, and eventually achieves the automatic production of single beam. Besides, it possesses the leading production line of steel pretreatment, V-method cast steel production line, the production line used for the decoiling, levelling and shearing of large steel, plasma CNC cutting, large-scale floor type borer, CNC gear shaper, vertical machining center and heat treatment CNC quenching machining tool and etc domestically. It also researches and develops double beam and main-beam hydraulic resistance welding machines in the advanced level of China and adopts the automatic systems such as hydraulic pressure and electromagnetism, etc. which all help the company both achieve the weldless double beam plate less than 80t and meet the demand of welding of different height of box beams. It researches and develops the national advanced main beam welding manipulator with Shanghai WTL together (Shanghai WTL Welding Equipment Manufacture Co., Ltd.), achieving the one-time welding of four main welding lines of the single beam.
