Large cranes are typically assembled on-site using smaller mobile cranes or other heavy equipment to lift and position the various components. The process usually starts with the foundation being laid and anchor bolts being secured. Next, the base of the crane, known as the mast, is erected and secured to the foundation. The jib, counterweights, and other components are then lifted and attached to the mast, followed by the installation of the crane's control system. Finally, the crane is tested to ensure it is functioning properly before being put into operation. **

Finally, the crane's counterweights and the lifting mechanism are installed. It's important to follow the manufacturer's instructions and have a trained crew assemble the crane to ensure safety and proper functionality. **
