What kind of help can the crane manufacturer give in the installation process of the gantry crane? For these questions, we will answer them one by one today. We will share with you the 2016 Saudi Electric Power Company's installation process of gantry cranes as a case study.
Under normal circumstances, when the customer needs to install the gantry crane, we can send an engineer or help the customer introduce a local experienced engineer to guide the customer to install it. In this case, we sent engineers to Jeddah, L'Arabie Saoudite via Abu Dhabi
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.
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.
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.
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.
The engineer will guide the workers do the electrical workers to do the electric with the help of boom lift.
After all the mechanical works and electrical works finished, we have to test and commissioning the crane.
