1. Independent installation
The truck crane is mainly used. After the bottom beam is installed and fastened, install the foundation section, support section and standard section in turn, then install the outer jacket swivel part, then install the tower cap, rear arm, finally install the lifting arm, and finally install the remaining counterweight. After the above installation is in place (after the installation of the truck crane), it is required to jack up the joint to an independent height.
2. Attachment installation
As the work after the completion of the above-mentioned crane installation, the only additional work is to install the anchoring attachment device first, and then lift the tower crane section by section through its own jacking system until the required height.
