The eight advantages about the flat-top crane
1.reduce the dismounting requirements, lower weight, low mounting
height, dismount each mast at a time in the air, save the labor
cost, safety and fast.
2. it is suitable for crossover work of the cranes, without the
tower cap and pull rod, the safety will be increased when there
need the crossover work.
3. It is suitable for the special requirement about the height,
such as airport nearby, tunnel, workshop ,and the construction site
with high-tension cable.
4. It is suitable for the construction site that has the
requirement about the crane boom, it can be used as internal
climbing crane in the high-rise buildings, irregular roof or small
areas.
5. It is very convenient for dismounting in the restricted
construction site, dismount each crane boom at a time by manual.
6.The steel structure of crane boom has long using life and high
safety standard.
7. The crane boom is good applicability, high-usage,the design of
the topless tower crane boom is easy for realizing the
serialization and standardization. Reduce the design and making
cost.
8. Low design cost, short cycle, can much better satisfy the
multiple demands of the customers.
