Composite girder self-supporting crane can complete the arduous task of elevated lifting, 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. The modular design structure with prefabricated standard can easily expand with the expansion of the center of the working unit;



Easy to install and easy to move;



At present, the combined self-supporting crane supplied domestically is made of steel with a lifting weight of 75kg-2000kg and a total girder length of 10m (optional aluminium girder);



Compared with the traditional girder crane, the closed rail design makes its handling force only 1/3 of that of the traditional girder crane;



The truss rail design makes the span larger and the installation layout more flexible.
