Heavy Duty Express Railway Building Girder Launcher Erecting Crane


Product Description


Heavy Duty Express Railway Building Girder Launcher Erecting Crane is designed for highway and railway. According to the situation of present railway with less subgrade, more bridges and tunnels which connected too closely, our company design and manufacture the new and special beam launcher. It is mainly used for lifting concrete girders in bridge construction in general railway and highway projects.



Specific Operation Process of Launcher Erecting Crane

  • The required height on both sides of the longitudinal running track of the Express Railway Building Girder Launcher Erecting Crane is stable. The horizontal running track of the front, middle and rear legs requires level, and the spacing is strictly controlled. The three tracks need to be parallel.
  • When installing the concrete beam of the inclined bridge, the front, middle and rear legs of the bridge should be staggered in front and back, and the left and right wheels should be staggered in front and back. The pitch can be calculated based on the tilt angle so that the leg wheels can run on the same lateral track. (For more information, contact the manufacturer).
  • The longitudinal movement of the bridge crane requires all preparations, and it is required to be in place at one time, and it is not allowed to stop in the middle.
  • When the gantry crane carries the concrete beam longitudinally, the front legs need to be fastened and fixed by chain hoists and horizontal rails to improve stability.
  • When installing bridges with vertical and vertical slopes, measures should be taken to prevent longitudinal displacement of the bridge machinery to prevent slipping.
  • After installing the erection machine, it needs to be hoisted and tested. After testing with concrete beams, the bridge crane can be put into operation again and the installation work can begin.
  • When installing the bridge crane, pay attention to security inspection at all times. Every time a hole is installed, a comprehensive security check is required. If you find that the problem stopped working and deal with it in time, you can continue. Mechanical electrical failure is not allowed to work.
  • Overloading of installation work is not allowed, and tilting and lifting work are not allowed.
  • The processing material of the connecting pin needs to be carried out according to the requirements of the design drawing, and low-grade steel processing should not be used instead.
  • It is strictly forbidden to operate above the tenth and fifth winds. A rigging is needed to stabilize the bridge crane and lift the crane. When the bridge machine stops working, the power should be cut off to prevent accidents.
  • The longitudinal position of the bridge erecting machine needs to strictly control the position and size to ensure the smooth installation of the precast concrete beam.
  • Since the bridge machine is a large-scale special equipment for bridge installation, the operation of the bridge machine needs to be clearly divided and unified, and full-time operators, full-time electricians and full-time security inspectors should be set up. . Strict construction organization and measures to ensure construction security.

Dismantling And Maintenance of Launcher Erecting Crane

  • When removing the truss beam, it should be supported by the sleeper raft, and the mule should be firm and reliable. High-strength bolts dismantled after flame heating need to be scrapped and not inherited.
  • Workers entering the demolition site need to wear safety caps and protective shoes. Workers working on truss beams need to wear security belts. This is the basic security protection for operating bridge installation equipment.
  • Before dismantling, the electrician shall mark each cable and wire, and shall dismantle the dismantling site. Any unrelated employees are strictly prohibited from entering.
  • When there is a bolt that is temporarily dismantled, it should be dismantled after it has penetrated into the diesel. Do not allow strong impact or forced disassembly after heating with flame.
  • After the bridge girder is completed, the track should be laid, and the bridge crane should be opened to the bridge head for disassembly. The crew should identify the hydraulic fittings, cylinders and other components that need to be identified to facilitate disassembly and next assembly.
  • The dismantling work is organized and guided by the bridge person in charge and technicians in the reverse order of assembly.
  • The removed parts should be handled and stored separately, and the joints of hydraulic pipe joints should be sealed.

Checking Work

  • Check the brake. Brakes are commonly used for the operation of suspended railway bridges. Therefore, the spring of the brake lever and the brake is more severe. If deformation occurs due to wear, normal braking effects cannot be achieved. Check often.
  • In order to avoid hanging wear of the utility model due to long-term outdoor work, the manufacturer requires a rain cover for electrical equipment. The rain cover not only prevents rainy weather, but also rain during normal hours. It can also block the sunlight of the device, avoid the aging of the device caused by direct radiation, and increase the service life of the device.
  • For all types of protective covers, the ladder needs to be carefully checked to prevent injury.
