How the single girder gantry crane installed? In the part, the on-the-spot report will be digested for your reference.
When we met the customer, we go to gantry crane installation site with customer. And then made one plan how to install the single girder gantry crane and how many days do we need to finish the job and others
1. The process how to install the gantry crane:
2. 15 days estimate time to finish the installation of the gantry crane.
3. Installations workers and tools
After confirm the above details, we start the work directly.
Then we installed the four side rails for gantry crane with the help of workers.
As for the 5tons and 30m/20m span gantry crane, wheel load is heavy, so we choose the P38 rail for customer.P38 rail is fixed on ground by platen and clamp by bolts.
After this process finished, we begin to connect the bottom beam and legs.
Bottom beam and leg connection by bolts
After connect the two sides legs and bottom beams, we have to set the girders up on the rail. It would be good to choose one small wind day to set up legs.
Finding the center of box iron which was welded already on the two legs and using the truck chain to fix it, then lift it up and put it down on the rail slowly.
After the left two legs were lift up, we have to use the wire rope and chain to fix the center of box iron also. One left two legs need two chain block fix on each side. If this finish, then another one.
Seting up the legs by truck crane
Let the truck crane lift the main girder up and keep about 1.5 meters distance up from ground. Ship the hoist to the bottom of main girder and fix it tightly.
Connect the cables and limit switch etc
We have to use the truck crane to lift main girder up slowly and we have to find two person at least to climb to the upside of legs when there is one good position between the legs and main girder. The two person of each side have to make sure the main girder edge is in the side of the bolts. Then put it down and let the welder to weld the girders and legs. We have to weld at least two spaces of each connection sides before we remove the truck crane.
After all the weld finished, it means all the mechanical works finished.
