According to by the weight of hanging device, generally select for use master's crane to get final product; If big especially, also can select two master's cranes for use by hanging device weight.
The suspension centre of described slide tail crane is arranged on by the hanging device center of gravity with upper/lower positions, and the suspension centre of described master's crane is arranged on by the above position of hanging device center of gravity.The relative position of the suspension centre of slide tail crane, the suspension centre of main crane and equipment center of gravity is specifically located according to the lifting ability of slide tail crane and main crane.
The concrete of suspension centre determines that principle is: the weight that main crane is born with slip weight that the tail crane born and main crane suspension centre to by the distance of hanging device center of gravity and slide tail crane suspension centre to being inversely proportional to by the distance of hanging device center of gravity.
Compared with prior art, because having adopted a kind of many cranes (being self-propelled crane) oppositely to lift to hang, hanging method provided by the present invention moves the method lifting by hanging device, after the slide tail is finished, the tail crane that slips lifts by hanging device simultaneously with main crane, therefore under the situation of quantity that does not change crane and lifting ability, the lifting ability of hanging method provided by the present invention increases greatly, and short construction period.This law can be used for the lifting of vertical equipment, has more preceence during in particular for the lifting of ultra-large type vertical equipment.
