Q:Under what circumstances are winches used and under what circumstances tower cranes are used?
1, this depends on the specific construction organization design, the general height of less than 20 meters, all with the hoist.2, the framework of the structure, four, 18 meters, construction area, if large, with tower cranes, of course, labor-saving, time-saving and rapid progress, if the construction side agrees, it is best to use tower cranes.3, artificial wages are too high, the project is big, with the winch is not worthwhile, progress can not catch up, workers are also big grievances. The track type tower crane is usually used in shipyard or fixed freight yard.
Q:How to select tower crane type according to the height of building? Seek explanation
