Problems solved by technology
[0002] At present, in rail transit construction or building construction, it is often necessary to transport mobile beams and heavy parts, and ordinary transport equipment cannot meet the needs of rapid movement
However, due to the limitations of the construction environment and space on many construction sites, cranes and general large-scale beam erecting equipment cannot reach this field for construction. It needs to be realized by gantry crane
[0003] However, the current gantry cranes are too bulky and inconvenient for installation and transportation; in addition, the current gantry cranes cannot be adjusted according to the actual construction environment, and after the universal wheels are installed at the bottom, it is very easy to shake when hanging objects

The invention provides a manufacturing method of a simple dual-track gantry crane. The manufacturing method comprises the following steps: 1, manufacturing two groups of chassis; 2, manufacturing twogroups of support devices; 3, manufacturing a lifting device; 4, connecting the bottom of each group of support device with one group of chassis through a bolt, arranging two rows of joist steel between the tops of the two support devices side by side, and enabling the two ends of the two joist steel to be connected with the tops of the two support devices through bolts; and 5, adopting a hydraulic control system to control all hydraulic devices, adopting a controller to electrically control all motors, and uplifting the entire mounted device. The simple dual-track gantry crane is suitable formultiple types of construction sites, can be adjusted according to the construction environment and is more convenient to mount and move.
Description
technical field [0001] The invention relates to the technical field of simple gantry cranes, in particular to a manufacturing method of a simple double-track gantry crane. Background technique [0002] At present, in rail transit construction or building construction, it is often necessary to transport mobile beams and heavy parts, and ordinary transportation equipment cannot meet the needs of rapid movement. However, due to the limitations of the construction environment and space on many construction sites, cranes and general large-scale beam erecting equipment cannot reach this field for construction. It needs to be realized by gantry crane. [0003] However, the current gantry cranes are too bulky and inconvenient for installation and transportation; in addition, the current gantry cranes cannot be adjusted according to the actual construction environment, and the universal wheels installed at the bottom are very easy to shake when lifting objects. [0004] Therefore, ...
