[0077] Balanced lifting mechanism 3 includes adjustable balance component and adjustable connecting component slidingly connected on adjustable balance component, adjustable connecting component is used to detachably connect with the set position of bridge machine component, and adjustable balance component is used to adjust the included angle between bridge machine component and horizontal plane;

[0079] It should be noted that when high-altitude hoisting is carried out on the constituent components of bridge machine, part of the constituent components need to be pre-assembled on the ground before being hoisted integrally, then the position of adjustable connecting component is adaptively adjusted to adapt to the connection of different bridge machine constituent components, and the center of gravity position of the overall construction is calculated and determined according to the design drawing, then the connection mode between adjustable balance component and tractor 2 is adjusted, so that the overall component can always keep balanced state in the process of hoisting, thereby reducing the complex construction process of adding counterweight on the overall component, and in the process of hoisting, when the connection process such as butt bolt is carried out, the adjustment path of space position adjusting component is determined according to the design drawing, auxiliary component 48 is moved along the set path by space position adjusting component, and in the moving process, when passing through the area where staff stand safely, movement is paused, staff install connecting piece, such as bolt, into auxiliary component 48, and then auxiliary component 48 with connecting piece is moved to the set connection position by space position adjusting component, which is mostly suspended position, so as to assist the staff to install the connecting piece, such as bolt, by inserting the bolt into the connecting hole from the suspended position, and the staff only need to connect nut in the safe area.
