Rise steel engineering cranes installed

Rise steel major mechanical installation of tower cranes. The selection should be based on the structure of planar geometry and dimensions, components, weight, etc.. Tower crane choose the general case, as far as possible outside with cranes, easy disassembly. Elected tower crane attached to the outer, Taki optional in the basement or another Taki; elected with climbing tower, tower cranes generally located at the elevator shaft. The position and performance of the choice of the position and performance of the tower crane tower crane should be able to meet the following requirements:
1) To make the length of the arm has enough surface coverage (buildings);
2) have sufficient crane capacity, to meet the requirements of the different location component lifting weight;
3) tower crane wire rope capacity to meet the requirements of the lifting height and lifting capacity; the steel engineering  speed have the grades to meet installation requires;

4) multi-machine operation, should be considered: When the tower crane is horizontal arm, the arm must have enough height difference, not collision should be adequate safety distance between each tower crane capable of safe operation to ensure the interoperability of the arm with the tower collision; crane jacking jacking, anchoring, or climb the tower crane, anchor or climb should consider the following questions: 1 attached to the outside of tower crane hook height shall meet the requirements of the height difference between the mounting height and tower crane, and in accordance with the tower crane tower body to allow the free height to determine the anchoring number of times. The anchor point of the tower crane should be conducive to the strengthening of steel structures, and the first to form the framework of the overall structure conducive to the curtain wall installation site. Anchorage points should be calculated. Within the climbing tower crane tower crane climb the position should meet the the tower free height and steel structure of each section of the column unit installation height requirement. Should be calculated to determine the inner climbing tower crane base with steel beam - column connection method. Climbing tower crane location within the steel structure, should climb before welding is completed, to form a whole.
Li, dismantle the tower crane Notes

1) selection of tower crane legislation to consider the construction site, the demolition of the condition of the tower crane.
2) legislation tower.steel engineering  attached tower crane in deep foundation pit slope established tower, Taki can choose according to the specific circumstances of stationary or walking base, but to consider the foundation pit slope stability, to consider the value of the maximum wheel pressure and appropriate safety measures . Within the climbing tower stand tower can be used inside buildings and steel on the platform.
3) The demolition of the tower. Externally attached tower crane, the main consideration should be given to the impact of the construction of high-rise buildings housing the demolition of the tower. Within the climbing tower demolition to rely on the the roof crane disintegration, so to be considered buried shall not be greater than the carrying capacity of the steel structure of the roof hanging maximum the wheel pressure value and track.
4) Where the legislation, dismantle the tower crane caused the pit, the additional load of the steel structure, shall require the prior structure checking.
