How to install the gantry crane? What issues should be paid attention to during the installation process? 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.
The main parameters of installing the gantry crane
Type of crane: Single girder electric gantry crane
Lifting capacity: 5tons
Lifting height: 16 meters
Span: 30meters
Gantry Crane installation in Saudi Arabia
Saudi Arabia single beam gantry crane installation process
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, Saudi Arabia via Abu Dhabi
Work out the installation plan for the gantry crane
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:
Install the rail
Connect the end carriages and bottom beam
Set up the legs
Lift up the main girder and installed the hoist
Put down the main beam on the legs
Electrical works
2. 15 days estimate time to finish the installation of the gantry crane.
3. Installations workers and tools
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
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 others
After confirm the above details, we start the work directly.
Installation of side rails of gantry crane
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.
installed the four side rails for gantry crane
Connect the bottom beam of the gantry crane to the legs
Firstly you have to know there are two bottom beams and four legs for each crane. It means one bottom beam shall connect two legs.
Connections by bolts also.
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. 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. After all holes were connected by bolts, try to shake it to check whether the connection is steadily .If ok, then do another one leg.
Then the engineer has to ruler the distance between the two legs. This distance shall be same with the saddle of main girder.
If distance ok, then find one box iron to weld it on the legs to make sure the distance steadily when it was lifting up.
Rail inRail is fixed by the bolts,clamps and platenstallation for the 5 ton gantry crane
Bottom beam and leg connection by bolts
Lifting and setting the legs up on the rail
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
Install electric hoist on the main beam of gantry 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
Installation and commissioning of gantry crane electrical equipment
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.
Gantry Crane in Saudi Arabia
The installation of gantry cranes is a very complicated matter, but as a global crane manufacturer, we have a complete set of crane solutions.
