[Problem] within which participants climbing tower crane models and advantages are?

 

[Answer] after nearly a century of development, the tower crane in the 2010s and today has spawned a lot of variety, in the form design can be divided into self-elevating tower crane, inner climbing tower crane, topless tower machine, boom tower crane, tower crane, and so quick. Wherein the inner climbing tower crane in the construction of high-rise buildings often used.

 

And for common tower crane attached different inner climbing tower crane is installed inside a building (the elevator shaft or stairwells ad hoc bay). Construction surface for the whole round. This large building density in urban construction, is particularly important. Because horizontal crane boom across the street, easy and buildings, wires, pipes and other collision, an accident could occur, resulting in danger.

 

Generally, internal climbing tower crane with a valid construction capacity, low cost, low cost, safe and tower assembly material library small footprint, etc., but in China's current standard classification, tower Crane standard model is QT, where "Q" represents the "crane", "T" stands for "tower", and since the inner climbing tower crane slewing mechanism in the upper part, the serial number on it, The same kind of tower crane is "QTZ" - that is classified in the "Back to the switched-lift on" crane column.

 

Inner climbing tower crane, also known as "climbing tower crane", so some manufacturers of such models has also been classified as a separate category, giving "QTP" prefix in coding. The inner climbing tower crane numerals and other models remain consistent standards. For example QTP40 (4908) shows "Nominal lifting moment is 400KN? M, 49 m boom, boom lifting at 49 meters (end lifting) weight 0,8T climbing tower cranes," where 40 referring to the 40 torque units, a unit corresponding to 10KN? m, brackets 49 are arm length, "08" refers to 0.8 tons.
