Project: Installation of Light Polls at intersection fly-over complex of King Khalid Road in Riyadh. Owner: Ar Riyadh Development Authority. Client: Al Babtain Corporation/Al Mabani. Location: KSA, Riyadh. Year: 2017. Equipment: Terex-Demag CC 8800-1 (1600 ton) crawler crane, Terex AC 250-1 mobile crane, special engineering. GHHL was contracted to install 33 Light polls on the intersection fly-over complex in Riyadh, King Khalid road. Light polls was consist of tower and Sphere, which vary from 20 to 33 tons, with diameter from 5 to 9 meter. The assembling of Spheres took place at site. The main technical requirement from Client was to avoid to place any crane on the fly-over, because of damage risk. GHHL provide sophisticated engineering solution and offer to execute the installation with single crane from the one position. We perform installation of Polls and Spheres with Terex-Demag CC 8800-1 crane with SSL 158 meter, which is maximum possible boom length for this crane. The maximum lifting Radius was 138 meter, which was on the edge of Manufacturer Load chart. The installation activities was performed during night time, because fly-over traffic was stopped due to safety reasons. GHHL successfully completed all activities in 2 month. Main challenges: work at night, heavy lift in darkness, control of 158 meter boom and precise engineering solution.
