Tower crane is the most commonly used lifting equipment on construction site, also known as "tower crane", with section by section extension (height) (referred to as "standard section"), it is used to lift construction materials such as steel bars, wood ridges, concrete, steel pipes, etc. Tower crane is an essential equipment on the construction site.
Normally we have the classification of Topkit Tower Crane, Topless tower crane and luffing jib tower crane.
The topkit tower crane mainly has three working types including stationary , traveling ,and inner climbing type.
The topkit tower crane has some features such as the advanced and resonable design, compact structure, good speed regulation performance, stable running and little impact, easy to operate, high using efficiency , accurate locating, high safety and reliability , big load capacity , and wide application scope.
2. The Topless Tower Crane has some features , such as module design, and good universality. And the flat tower head is suitable for the group of tower crane working together. The assembly and dismantling are more convenient , which have the low requirement to the lifting equipment. Besides, the topless tower crane has long service life on the steel structure, high safety and other advantages.
3. The luffing jib tower crane mainly include the stationary, traveling and inner climbing type .The luffing jib tower crane has some features such as follows. Invasion to the sovereignty over airspace can be avoided efficiently through the luffing jib. Meanwhile, as the short counter-jib, it is suitable for the constructing in the commercial intensive area and narrow area.
