This distance shall be same with the saddle of main girder. Then the engineer has to ruler the distance between the two legs.After all holes were connected by bolts, try to shake it to check whether the connection is steadily. When you keep the hole between the bottom beam and legs at the same spot, use one steel stick to hold it and connect all the holes soon by the bolts. Put the bottom beam down on the ground with enough spaces, then lift the legs up and moving it slowing towards to the bottom beam directions.It means one bottom beam shall connect two legs. Firstly you have to know there are two bottom beams and four legs for each crane.Then we installed the four side rails for gantry crane with the help of workers.Īs 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.Īfter this process finished, we begin to connect the bottom beam and legs. Tools needed: 4.0 lever weld rod, 4 chain blocks with 1ton capacity at least, Tools box, including the wrench, spanner, screw driver, welding machine and othersĪfter confirm the above details, we start the work directly.Workers required: 2 welders at least, 4 mechanical workers and 2 electrical workers, 1 driver to control the 30tons truck crane, 1 driver to control the boom lift/scissor lift.15 days estimate time to finish the installation of the gantry crane. Lift up the main girder and installed the hoistĢ.Connect the end carriages and bottom beam.The process how to install the gantry crane: 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 othersġ.
When we met the customer, we go to gantry crane installation site with customer. Work out the installation plan for the gantry crane
