塔吊抗倾覆验算（Anti overturning calculation of tower crane）

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 square meters. Two, the selection of tower crane: The project area is large, wide operation, brings some difficulties to the location selection of tower crane. According to manufacturer specifications, types and characteristics of the project and the actual situation, the project adopts QTZ63 series D5610 type tower crane 3, vertical and horizontal transportation for materials and equipment to the construction site, the crane performance of this model is reliable and safe and convenient operation, the design department of the Ministry of construction Changsha construction machinery research and Design Institute Hunan South Building Machinery General factory. The three section layout. The basic can cover the whole surface of the construction, meet the height, amplitude. Three, the plane position of tower crane Crane position principle: the crane can rotate 3600; maximum coverage area; the construction site as far as possible without blind area; no influence on surrounding buildings; no touch, and safety between tower crane. 1, layout: To ensure the safety of production, reliable quality, convenient operation, vertical transportation of materials, semi-finished and finished products to cover the maximum working surface of the lifting range and rotation radius, and more than a little, to achieve the best efficiency and the best economic benefits, by comparing and investigating the decision. 2, the base position: 2# tower crane tower crane base is arranged in the center of D5610 (2 A) 3.6m (2 - south axis 21 axis South East 3.3m, 3.6m). Parallel to the axis of the base (2A). (see Figure plane position). The center coordinates: X = 88055.728, Y = 49579.670. The geological exhumation of t
