Composite girder self-supporting crane can complete the arduous task of lifting elevated, and can undertake frequent elevated material transportation.
It can be mounted on any ordinary 15 cm thick reinforced concrete floor without exerting pressure on the roof structure of the building. It can easily expand with the expansion of the center of the working unit by using prefabricated standard modular design structure.
Easy to install and easy to move.
At present, the combined self-supporting crane supplied in China is made of steel with lifting weight ranging from 75kg to 2000kg. The total length of the main girder is 10m (optional aluminium main girder).
Compared with the traditional girder crane, the closed rail design makes its handling force only 1/3 of the traditional girder crane.
