Tower Crane-FZQ2520
- Product Details
- Company Profile
FZQ2520 attached self-climbing tower crane is an upgrade of “FZQ attached self-climbing tower crane series” and the biggest luffing jib tower crane in China series of products is a new type of tower cranes containing the most technological content and the most advanced performances in China at present. They have used advanced imported mechanism in the world and high strength materials, and a few pieces of technology adopted has filled domestic blanks. Their comprehensive performance is advanced globally. Adopting trolley travelling mechanism on luffing jibs, upper slewing, upper climbing, postposition of boom hinge point and attached tower body, FZQ attached self-climbing tower crane series is characterized by big lifting height, big lifting capacity, wide range of operation, great wind resistance, light dead weight, flexible layout, easy installation and dismantlement and low costs for site transformation, installation and dismantlement. self-climbing tower crane series products are applicable to the installation of thermal power stations, hydro power stations and nuclear power stations, petroleum, chemical, and metallurgical industries, high-rise steel structure and other large construction projects, particularly in the construction of tower boiler power stations and other cases where the construction site is so narrow that other types of cranes can not work. The tower body of FZQ2520 attached self-climbing tower crane is composed of foundation section, standard mast section and attached section, which have the same section size. The tower body is a modular dismantling composite of tube truss structure. The main chord has a big section, the tower body has a small section, and the web members are K-shaped. The main chords in the tower body are standard components which are connected with taper pins. The tower’s standard section and attached section can be interchanged during installation as required by site conditions. The sections of the tower body are join
