Embodiment
[0029] The installation method of the large bridge crane provided in this embodiment, its installation method comprises the following steps:
[0030] A. Organize the hoisting site to ensure the strength and flatness of the site; B. Use drawing software to draw the layout of the crane components through multiple computer simulations of hoisting and on-site surveys (such as figure 1 shown) and reserve the location of the truck crane, where the truck crane is located below the crane that needs to be installed; C. According to the weight of the main girder, sub-beam, end beam, main trolley in the crane and the hoisting height required on site, choose a Car cranes for hoisting weight and height, among them, because the main trolley is too heavy as a whole, before hoisting, its drum, motor, reducer and other components need to be removed; D. Check whether each hoisting equipment is qualified, and use the car crane to separately The main beam, auxiliary beam, end beam, auxiliary trol...

Abstract
The invention discloses an installation method for a large bridge crane. The installation method for the large bridge crane comprises the following steps: S1, carrying out construction preparation; S2, assembling a main beam at a left side and a main beam at a right side respectively, assembling two secondary beams at the middle part, and end beams, and installing heat-isolation plates below the main beam at the left side, the main beam at the right side, and the secondary beams; S3, sequentially lifting the main beam at one side, and the secondary beams and the end beams which are integrally assembled, and fixedly installing the main beam at the side, and the end beams; S4, lifting the main beam at the other side; and S5, sequentially lifting a secondary trolley and a main trolley. According to the installation method for the large bridge crane, which is disclosed by the invention, the maim beams, the secondary beams and the end beams are lifted by virtue of an automobile crane, and the main trolley is lifted in the form of cooperating the automobile crane with a traction device, thus consumed number of automobile crane groups, and the labour cost of operation are reduced; and one automobile crane is used for lifting, thus lifting difficulty for the main trolley can be reduced, and construction safety and quality are guaranteed.
Description
technical field [0001] The invention belongs to the field of hoisting equipment installation, and in particular relates to an installation method of a large bridge crane. Background technique [0002] Large-scale bridge cranes have many components, and the main girder and auxiliary girder are tens of meters long. At the same time, the frame of the main trolley is large, and the requirements for the tonnage and site of the truck crane are high when the equipment is hoisted at high altitude. These hoisting contents are the top priority of construction safety and quality control heavy. [0003] At present, the hoisting method of the bridge crane is mainly to lift the main girder, auxiliary girder, and end girder to the installation position before assembling, and then hoist the auxiliary trolley and the main trolley in turn. When hoisting the main trolley, the following two methods are mainly used for hoisting: one is to use a single truck crane to hoist from one side after th...
