Gansu gantry crane | gantry cranes | gravity provided by the Henan Province, Henan Crane Co. gravity. Road Zhiyuan, temper forward. Gravity Henan Province Crane Co. (www.zlqzj.com.cn) strives to be and you win, symbiosis, strategic partners to move forward, the more determined to become the machining of the most influential business, and you leap together to succeed ! Henan Province gravity Crane Co. (formerly Xinxiang recorded Army Crane Co., Ltd.) is a domestic and international reputation for excellence, one of the larger crane professional manufacturer. Mainly engaged in single and double girder cranes, gantry cranes, ship cranes, bridge machine, grab, electric hoist, and other lifting equipment manufacturing, sales and installation. Bridge Crane bridge from the main box, grab the car, traveling mechanism, cab and electrical control system. Extract device is able to crawl grab the bulk material. Bridge Crane has opening and closing mechanism and the lifting mechanism, with four rope grab were hung from the opening and closing mechanism and lifting mechanism. Opening and closing mechanism driven grab closed, grab the material, after bucket mouth when closed, immediately start lifting mechanism Gansu gantry cranes, wire rope making four average load carried by the lifting work. Only start when the discharge opening and closing mechanism, then open bucket mouth, tilt materials. Bridge Crane hoisting mechanism in addition to the different external Jilin gantry cranes, overhead crane part with the rest of the structure is basically the same. Gravity Henan Province Crane Co. (formerly Xinxiang recorded Army Crane Co., Ltd.) is a domestic and international reputation for excellence, one of the larger crane professional manufacturer. Mainly engaged in single and double girder cranes, gantry cranes, ship cranes, bridge machine, grab, electric hoist, and other lifting equipment manufacturing, sales and installation. Crane hoisting mechanism including run institutions, luffing mechanism, slewing mechanism and metal structures. Lifting mechanism is the basic working mechanism cranes, mostly by hanging Dalian gantry crane and winch system composed but also lift weights through the hydraulic system. Run institution for vertical or horizontal transport of heavy adjust the position of the crane gantry crane work, usually by the motor, reducer, brake and wheel components. Luffing mechanism is equipped with only the jib cranes, jib looked up when the amplitude decreases, the amplitude increases when bent, sub-amplitude balanced and unbalanced two amplitude. Boom slewing mechanism for allowing rotation is determined by the drive and slewing ring device component. Metal skeleton structure is a crane, the main bearing member such as bridge, boom and mast may be a box structure or truss structures, but also for the web structure, and some can be used as the supporting steel beams.
