随着城市基本建设规模的不断加大,大型工程和群体工程越来越多,单台塔机已经不能满足施工中的垂直和水平运输需要,多台塔机甚至几十台塔机群体作业司空见惯。由于单台塔机作业覆盖面呈扇形,要保证施工中对作业工程的全部覆盖,必然会出现塔机作业平面相互重叠现象,作业面相互重叠必然会导致相互间的干扰,运行中就可能存在作业碰撞。因此,为保证群塔施工中的相互运行安全,减少安全事故,同时又尽可能地满足施工需要是群塔施工中需要解决的主要问题。
With the increasing scale of urban infrastructure, large-scale projects and population engineering more and more, a single tower crane has been unable to meet the construction needs of the vertical and horizontal transport, tower crane or even dozens of tower crane group operations commonplace . As a single tower crane operation coverage was fan-shaped, to ensure the construction of the full coverage of operations, tower machines will inevitably appear overlapping workstations, overlapping work surfaces will inevitably lead to mutual interference, the operation may exist operations collision. Therefore, in order to ensure the safety of each other in the group tower construction, reduce accidents and at the same time meet the construction needs as far as possible is the main problem to be solved in the construction of group towers.
