The Steel Structure with Long Lifespan and High Safety: Compared with a high-top tower crane, the flat-top tower crane has an obviously different connection type and force condition. Its upper structure is rigid and placed horizontally. Without the pull rob of the jib, this tower crane is not affected by the alternating stress vertically or horizontally, which significantly enhances the lifespan and safety of the steel jib structure.
The flat-top tower crane is designed without any pull rod so as to reduce the height of the tower top and meet the requirements on different work sites. It is especially suitable for disassembling and assembling on restricted construction sites or during the multi-tower cross operation, which immensely boosts the tower crane working efficiency. This machine has low unit weight and low mounting height. The height difference between tower bodies can be reduced to save much space and cost.
