第六步：利用垂直升降系统提升整个桁架，摄像机系统安装时，先利用垂直升降

Step Six: lifting the entire system with a vertical lift truss, the camera system is installed, with a vertical lifting system to decrease the entire truss, the camera system and the related installation cables in place after the installation is completed by a vertical lifting system rises the entire truss, for increased fine-tuning, and finally to the entire system maintained at the design position.

Step 6: The use of vertical lifting system to lift the entire truss, camera system installation, the first use of vertical lifting system to reduce the entire truss, installation of the camera system and related cables, after installation, the use of vertical lifting system to rise the entire truss, rise to position after fine-tuning, and finally make the whole system remain in the design position.

Step 6: use the vertical lifting system to lift the whole truss. When the camera system is installed, first use the vertical lifting system to lower the whole truss, install the camera system and related cables, and then use the vertical lifting system to lift the whole truss after the installation is completed. After the lifting is in place, perform fine-tuning, and finally keep the whole system in the design position.
