Shandong Huaxia Group is a professional manufacturer of construction machines .It passed ISO***1:*4 quality mangement system accreditation in ***9 and passed ISO***1:***2 quality mangement system accreditation in ***2.The sale of its tower crane has been listed the first place in China since ***8 and its tower cranes are exported to Algeria ,Russia,Guinea-Bissau,Vietnam and Tran and other countries.The QTZ**5(HX***4) tower crane is a new large building crane designed and manufactured by Shandong Huaxia Group in ***3.Its steel structure were designed by FEA.We used tower crane computer software to make the parameter optimization and stability computation of complete crane and parts ,which are up to international leading level. Various performance and technologies of QTZ**5(HX***4)tower crane take lead in all similar products in China.Its merits are as follows: The maximum length of its jib can be *0m and also can be reassembled to *5m,*0m,*5m,*0m, which can have a wide work range spite of barriers.The anchoring tower crane has the hoisting height of *6.2m.The tower crane use fluid drive system to increase or decrease mast height so as to make proper crane height for different building height.The climbing tower crane has the hoist height of **1m.At specific requirement and through special treatment ,the anchoring tower crane can have the hoisting height of *1.2m and the climbing one can have the hoisting of **0m.The tower crane has the horizontal jib and double trolley traveing length.Load hangs to trolley and change workingradius with the traveling of the trolley on jib.When changing speed,steel rope can hang only one trolley so as to lighten the tower crane and hang more loads.Compared with jib-moving tower crane,the crane is more stable ,easier to install and has a wider working radius.And building materials can be in a wide range .The tower crane has complete safe devices such as hoist height limiter,trolley traveling limiterf ,hoisting moment limiter,hoist load limiter and tower crane rotating limiter .All these devices are sensitive and relible .All devices have aresters for safe working .Its driver&#**9;cab is very comfortable and has big space and good visual field.The electric control system an all parts have good performance ,are east to buy and repair.
