Truss type concrete bridge beam launcher gantry crane manufacturer
Product Description
Truss type concrete bridge beam launcher gantry crane manufacturer is a professional design for U type bridge machine required for erection of city rail transit construction beam. As a kind of structure section, the U beam has good noise reduction effect, low construction height, high utilization ratio of cross section space.
Because of U type beam for thin-walled opening structure, the traditional bridge rack beam cannot be applied directly. Unable to realize the traditional function of carrying beam traversing, beam body installation can only be achieved by traversing the crane. Therefore truss type concrete bridge beam launcher gantry crane manufacturer, acquired vehicle girder, two cranes synchronous walking, then synchronized fall beam" of the process, simple operation, safe and stable.
Safety is the most important issue for cranes. To ensure the safety, the following safety devices are equipped in truss type concrete bridge beam launcher gantry crane manufacturer.
Crane traveling limit switch.
Overload protection device.
Lifting height limit device.
Voltage lower protection function .
Phase sequence protection function.
Emergency stop function.
Rain cover for outside hoist, driving units, electric cubicle.
Warnings indicator : flashing nights and warning sounds.
Wire-less infra-detector for anti-collusion.
