The eight advantages about thetopless tower crane

1, the toplesstower crane reducethe dismounting requirements, lower weight, low mounting height, dismount eachmast at a time in the air, save the labor cost, safety and fast.

2, it is suitable for crossoverwork of the cranes, without the tower cap and pull rod, the safety will beincreased when there need the crossover work.

3, It is suitable for thespecial requirement about the height, such as airport nearby, tunnel, workshop,and the construction site with high-tension cable.

4, It is suitable for theconstruction site that has the requirement about the crane boom, it can be usedas internal climbing crane in the high-rise buildings, irregular roof or smallareas.

5, It is very convenient fordismounting in the restricted construction site, dismount each crane boom at atime by manual.

6, The steel structure of craneboom has long using life and high safety standard.

7, The crane boom is goodapplicability, high-usage,the design of the topless tower crane boom is easyfor realizing the serialization and standardization. Reduce the design andmaking cost.

8, Low design cost, shortcycle, can much better satisfy the multiple demands of the customers.
