wind cable rope initial tension
powered palle ttruck is not working when the mast rope cable pre-tension force of the wind. Rally Rally beginning to take work for 15% -20%.
2 wind cable pulling rope work
Work force is at work mast cranes, wind cable rope assumed loads.
In the right wind cable wire process layout, there is always a wind cable hoisting rope is determined by the vertical axis and the mast vertical plane, this root wind cable wire called the "main wind cable rope."
3 wind cable rope selected basic principles: all wind cable wire rope shall be selected according to the main wind cable.
Selection for wind cable wire to the main cable tension and wind the rope work and as the basis of the initial tension.
(Three) types of anchors, anchor calculations
Type: Full buried, half buried, activity type and use of buildings
1 full Buried ground anchors can withstand greater tension, suitable for heavy lifting. Calculate the intensity normally be based on soil conditions and checking its horizontal beam material stability, vertical stability and beam intensity.
2 movable anchor to withstand the force is not suitable for renovation and expansion project. Calculate the strength necessary to calculate the horizontal and vertical stability stability
