塔吊抗倾覆验算(Anti overturning calculation of tower crane) A project overview Hawaii spring clean water project is located in Changsha Tian guihua. Two layer underground, 12 storey main building, frame shear wall structure, about 180 meters long, 65 meters wide, construction area of about 1040 s...
Tower craneStatic stiffnessControl valueStatic displacementThe static stiffness of tower cranes is studied by using the proposed formulations and finite element method in this paper. A reasonable control value based on theoretical calculation and finite element method is obtained and verified via collected...
including drafters of national standard of domestic tower crane industry, engineers of implementing earliest FEM calculation of China, and professionals of design calculation and manufacturing technique.Besides, the group also have more than 600 professional personnels of other aspects like sales,...
top tower cranes don't have design and calculation of tower head and pulling rod, less calculation work condition, simple mechanical model, calculation reduces that make results of calculation is closer to actual value, so that can be easy to proceed modular design, decrease time of desi...
And the wheel load detection method was proposed, which includes detection scheme design, sensor selection, sensor installation design and circuit design. This method offers a new way to perfect tower crane tip-over prevention plan. 展开 关键词: tower crane anti overturning stability overturning ...
The international top stress calculation software is used to analyze the safety of the tower crane structure, and the force on each node of the tower crane is calculated to ensure the overall safety of the tower crane. The three-dimensional solidworks software is used to design, and each compo...
When the overweight steel members are hoisted at high altitude, large internal-climbing tower crane must be adopted. 超高空吊装超重钢构件,需要大型的内爬式塔式起重机。 www.showxiu.com 9. finally, through examples verified the calculation accuracy and speed on fast processing software of tower crane...
(brick) in most cases has a round section.Towers are subject basically to meteorological stress—wind, temperature, and freezing. Calculations used in constructing towers are based on general rules of construction mechanics; a static calculation to determine durability, stability, and the degree of ...
This criterion enables calculation of the controller feedback gains for varying load weight and cable length. The position references for this controller are step functions. In the second approach, the transfer process and the swing control are separated in the controller design. We use a PD-...
6) tower crane foundation 塔吊基础 1. Based on the practical conditions and the engineering experience of the company,authors enumerate the normal design schemes oftower crane foundation,and put forward the calculation methods and the key points of construction for the example of QTZ63t·m outer-...
