Beam Launcher for concrete bridge beam of bridge construction site
Beam Launcher Bridge girder erection machine merges an adaptation of a wide range of work, good compact structure, convenient operation, whole crane body with safety steel structure. This product can be used not only in plain construction environment, but also can meet the construction situation of mountain highway slope, Ramp bridge.
Full Span Truss Type Bridge Girder High Working Efficiency Beam Launcher is used for erecting concrete box girders for high speed (250km, 350km) passenger railway lines. This machine is suitable for equal span girders or different span girders which can be 20m, 24m and 32m, 50m. The rear part has two supports. One of the supports is "C" shape column with rotary and foldable technology. The "C" shape column technology saved the traverse space during traveling and which enables to travel through tunnels with the girder transfer vehicle.
Beam launcher body includes main beam, cantilever, under guide beam, front and rear legs, auxiliary outrigger, hanging beam crane, cantilever structure and hydraulic driving system, with high performance and strong working efficiency.
This type launching crane is well applied in highway and bridge construction site and railway construction site. It can be used for environment of no fire, no explosion and no corrosive media with temperature from -20~55C.
Safety first. .To ensure its safety, below safety devices must be equipped:
▪ Crane traveling limit switch.
▪ Overload protection device.
▪ Lifting height limit device.
▪ Voltage lower protection function device
▪ Phase sequence protection function device
▪ Emergency stop function device
▪ Rain cover for outside hoist, driving units, electric cabinet
▪ Warning indicator : flashing nights and warning sounds device
▪ Wire-less remote detector for anti-collusion.
It usually consists of three parts: mechanical, electrical and metal structures. It is shaped like a single-span flat bridge with two ends supported on two parallel overhead rails. It can be roughly divided into lifting mechanism and trolley operating mechanism. And shopping cart run organization.
During the whole process, the lifting mechanism is used for vertical lifting and lifting; the trolley running mechanism is used for lateral load movement; the trolley walking mechanism is used for lifting the trolley and the longitudinal movement of the articles to achieve three-dimensional space. Used to handle and load cargo.
The above-mentioned metal structural components are reasonably arranged by various devices, so that the bridge crane can be used not only for loading and unloading in open-air warehouses, storage yards, railway freight stations, ports, etc., but also equipped with various special hooks. Carry out various special businesses.
There are also rules regarding choice. Under normal conditions, the lifting capacity is less than 50 tons, and the maximum hoisting machinery span is within 35 meters. It is recommended to use single-girder bridge cranes without special requirements. If the width of the door legs is required, the working speed is high, or heavy and long parts are often lifted, then a double-beam portal crane is required.
During operation of an overhead crane, slipping sometimes occurs. In order to eliminate this undesirable phenomenon, it is necessary to first analyze the cause of slippage and take corresponding measures according to different reasons.
For example, the correct selection of a bridge crane matching motor should not be too large; at the same time, the bearing capacity of the bridge crane and the load capacity of the wheel load should be calculated to ensure that the wheel has sufficient pressure on the wheel surface. In addition, the starting and braking time of the equipment must be properly controlled.
