QTZ105(HS5516P) tower by my company is developed and large tower. The tower forturning on the shelf, the car horn level arm, no tower cap, hydraulic ZiSheng.Rated lifting torque for 1050 kN m., independent erection was maximum liftingheight of 43.5 m, and attached to the maximum lifting height is 170 m, maximumlifting weight for 8 tons, the most greatly place up to 1.6 tons of weight, themost greatly for 55 m.

The biggest characteristic tower: (1) the standardsection of the space is little chip, transport costs low. (2) tower overallintensity is high, most of the materials are used the tower Q345B (manganesesteel), make use of the tower more security, the service life is longer. (3)due to the unique design, making the overall upper tower weight, reduce theprevailing wind direction, force reduction. (4) the flat roof top without towercap design, more can apply the requirement of cross homework, and can even makefull use of space and the effective high tower. (5) the forearm unique designhas altered the forearm force situation, no longer tension and compression ofalternating stress. (6) the forearm transformation convenient, do not need tobe born can change the forearm arm. At the same time the connection of thefestival is also very simple. (7) greatly reduce the disassembling of towercrane equipment needed for the lifting capacity requirements. Crew cut towerdue to the elimination of the tower head, the unit of small, height ofinstallation quality low, the biggest installation height of the tower at thesame level than other reduce more than 10 m. Ordinary tower crane boominstallation must be on the ground to arms frame, tension bar and so on allconnect the integral hoisting again, this time to the requirements of thelifting equipment is the highest, with a lot of lifting weight and liftingheight. Because arm root pin shaft even good after he will raise many big armsto the arm bars even good, install the arm bars was easy to appear safetyaccidents, and even tower was completely improve the installation. This designhas fully considered the special needs of the users, using a variety of basicform, especially the tower can be made according to the customer demand walktype, expand the application places.

The machine has a hoisting, slewing, derrickingand roof up four work units, but alone or composite action to improve the workefficiency. Roof up mechanism for mai take high or drop tower; Three biginstitutions through the variable frequency speed regulation produce variousdifferent speed to meet the needs of the different working conditions. Hoist boomcan be positive and negative spin 540 °, slewing, luffing flexible reliable, hoisting in placeaccurate, and can be one-time meet in vertical and horizontal construction oftransportation needs.

The machine has the weight limit device, torquelimiter, lifting height limit device, amplitude limit device and rotarylimiters device. Safety protection device is sensitive and reliable, ensure thenormal work tower. In addition, but also is equipped with the rest platform, such as fence safety protection facilities. The driver room independent sidebuy, beautiful modelling, vision and interior space is big, easy to operate.
