Y  Composition diagram of Jib crane

The jib crane is made up of base plate, pillar, fixing system, rotation bearing, Swivel bearing bracket, Diagonal reinforcement and jib (cantilever) etc
Prework before installation
Check the needed parts
Expansion bolt or chemical bolts on the base plate
Fixed screw for the bearing
Up and down rotation bearing
Rotation smooth shaft
Diagonal steel bar with positive and negative teeth
Mounting plate of jib
Mounting washer of base plate

Tools required and auxiliary facility for installation

Auxiliary facility: forklift, scaffold or platform truck etc.
2. Exam the installation condition of site
Whether the height from ceiling to ground reaches the request
Whether there is obstacle above the jib, whether there is collision for jib swing
Whether there is potential obstacle in the covering area of Jib
Make sure the thickness of concrete is not less than 200mm
Make sure there is power supply on site
Make sure whether there is compressed air on site.
3. Installers and safety measures
Warning board and warning signal in installation area is a must.
Must wear safety helmet in the process of installation
Must wear goggles and Protective earplugs in the process of installation
Must wear protective mask in the process of installation
Must wear work shoes protected with steel plate
The clothing of the installer must be fitted, free of involvement, no drooping or floating ribbons, etc
Must wear saftey belt which is fixed in the safe and inmovable object for aerial work  
The installers must coordinate with the worker on the ground for aerial work  
If welding is required on site, the Power indicateor must be installed, and the ground wire must be connected
If welding is required on site, fire protection facilities such as fire extinguishers, fire masks, etc. are required
Irrelevant personnel are prohibited from entering the installation area
4. Installation steps
With the aid of other equipment, erect the column in a vertical state
Determine the installation position of the pillar, and adjust the installation direction of the cantilever according to the visual inspection
After the position is fixed, drill a deep hole with a diameter of 22mm with an impact drill according to the opening position of the base plate, and the depth should be 180-200mm

FClean up the dust accumulated in the hole
FPut the expansion screw into the hole, and hammer lightly with a hammer to ensure that the expansion screw completely touches the bottom of the mounting hole
FAfter the expansion screw is in place, insert the flat washer and the spring washer into the thread in turn, screw in the nut, and tighten with a wrench
FPlace a level bar or level gauge on the pillar, add and adjust washer on the base plate according to the actual situation, until the pillar is completely level, fully tighten all the bottom plate screws, and check the level of the column again
FPut the bearing on the smooth shaft of the cantilever bearing seat. If the fit is tight, you can tap it with a hammer to ensure that the bearing will not come out.
FInstall the rotating bearing seat into the upper and lower mounting plates on the pillar, pass the mounting screws through the mounting plate, fix the bearing, the fixing screw is M12, and tighten the anti-falling screw.
FFix the diagonal brace with positive and negative teeth on the cantilever bearing seat
FInsert the aluminum profile rail into the rail mounting hole and fasten it with a splint
FFix the other end of the diagonal brace on the aluminum alloy cantilever and fasten it with screws
FPut the level bar or level gauge on the aluminum alloy track, adjust the cantilever to the horizontal position by adjusting the positive and negative teeth, and tighten all the screws.
FAfter completing the installation, reconfirm the level of the pillar and cantilever
