Flat Top Tower Crane
One of the remarkable characteristics of a flat top tower crane, also known as topless tower crane, is that supporting components of the jib wont exceed the height of the boom. The top part of the tower crane is significantly different from that of traditional tower cranes with tower head. Determined by the special structure, its advantages can be highlighted specially in construction sites with limited space. When several construction cranes need to work close to each other on the same site, adoption of flat top crane is cost-effective. Without a tower head, the flat top crane lowers its self-standing height significantly and reduces installation time as well. Moreover, the height of the flat top cranes which work together at the same site can be relatively reduced. Meanwhile, central ballast of each luffing crane can be reduced as well. Therefore, the topless crane is suitable for construction sites in need of cross operation of multiple cranes and special tower height.
Characteristics
Made of steel structure, the jib features long service time and high safety. No pull rod will be required for support of the jib. With modular design, the jib significantly reduces design and manufacturing cost, thus bringing down the price of the flat top tower crane, fully applying its flexibility and adaptability and improving the utilization percentage of the boom sections. In addition, installation and disassembly of the jib is easy as well.
Even during construction process, there is no need to dismantle the whole jib when we need to change its length. All we have to do is add or remove related jib sections. The sectional size of the jib is larger than that of a comparable regular tower crane, thus reducing buckling deformation during loading. Hence, the topless tower crane is more suitable for construction circumstances requiring variation of working scope.
For electronic control system, reliable and superior quality international brand electric elements are adopted, thus ensuring high level of automation and easy operation. Moreover, the tower crane comes with five categories of safety limit devices to achieve safe operation. Fully equipped with safety devices, the interlock manipulation platform features easy operation, comfort, safety and easy maintenance.
Design of the whole machine is assisted by finite element software to ensure reasonable structure design and standard technical indexes. As a result, the topless crane can be used for lifting projects under complex circumstances. The tower crane has multiple working modes which include walking, fixed and internal climbing mode, etc.
