Cranes or tower cranes in high-rise construction.
The difficulty that high-rise building contractors need to solve is: That is, transporting construction materials to the highest heights, especially heavy materials… Therefore, to construct high-rise buildings smoothly and achieve high economic efficiency, it is necessary to solve the above difficulties well. One of the important issues is to choose the right machinery and use them properly, in which the tower crane is the most important, deciding the progress of the construction project. To use the tower crane well, it is necessary to pay attention to the following issues:
1. Specifications
Including: lifting capacity, crane moment, crane climbing ability, reach, maximum crane hook lifting height, crane weight, working speed of tower crane. Depending on the project, we choose the technical parameters to choose the appropriate tower crane.
2. Factors affecting the selection of tower cranes
Those factors are: ground shape, number of floors, height, volume, progress, foundation conditions and construction area, site traffic conditions, crane service supply of the unit and other economic efficiency requirements.
3. Location
A suitable tower crane location must satisfy the following requirements: reach and lifting capacity for foundation construction, construction of above-ground components, and must take into account the reach and reserve lifting capacity; There must be a detour, convenient for cars and other auxiliary cranes to enter the site; The tower crane location must be close to the circuit breaker; There must be enough space left for dismantling the crane and transporting accessories out of the site; If two tower cranes are installed at the same time, attention must be paid to dividing the working electricity, and measures must be taken to prevent mutual obstruction and work accidents. In addition, when choosing a crane location, it is also necessary to consider the option of running on rails or fixed.
Some outstanding advantages of Tower Crane
– Flexible body and boom structure is convenient for installation, disassembly and transportation. When installing the boom, a small crane can be used to install each boom section.
– With a compact module structure, the crane disassembly and assembly is very simple, quick and safe.
– When installing a flat-head tower crane, only a small tire crane with a short reach is needed for installation.
– No need to install a top and complicated boom suspension braces.
– Especially suitable for installation in narrow construction sites in the city because the boom can be installed in parts without needing to be assembled as a whole.
– The lifting arm, counterweight arm and turntable are connected very simply for easy disassembly and assembly.
– The flat-head crane is always the right choice to replace the conventional top tower crane, especially for construction sites using many tower cranes.
– With a sturdy design, no change in pressure in the lifting arm, it almost completely eliminates fatigue of the steel structure.
– Easily change the self-standing height according to the construction site’s usage requirements (The self-standing height is the height when installed without anchoring).
– When installing a flat-head tower crane, only a small tire crane with a short reach is needed for installation.

– The lifting arm, counterweight arm, and turntable are connected very simply, making it easy to disassemble and assemble.
– Flat-head cranes are always the right choice instead of conventional tower cranes, especially for construction sites using many tower cranes.
– Flat-head cranes can achieve maximum hook height with the lowest height for the entire crane.
– With a sturdy design, no change in pressure in the lifting arm, so it almost completely eliminates fatigue of the steel structure.
– Easily change the self-standing height according to the usage requirements of the construction site (The self-standing height is the height when installed without anchoring).
– The lifting cage is specially designed to allow the crane to be disassembled or lifted from 04 directions (especially convenient for the process of disassembling and lifting the crane).
