UAE Pavilion 

Client: Arabtech / Adnoc / Turner and Townsend

Year: 2017

Project: UAE Pavilion

Work Location: Dubai Expo 2020

Description: Mammoet deployed one of its 750t crawler cranes – Liebherr LR 1750 to lift and install the ‘wing’ panels of the UAE Pavilion roof. The weight of the panels ranged from 6t to 16t with lengths varying between 24m and 61m. Due to the size of the panels and the large surface area-to-weight ratio, the permissible lifting wind speed was reduced to 3.4 meters per second to ensure safe operations. All panels were installed at night to accommodate the continuity of other construction activities at the UAE Pavilion during daylight hours. Each panel was lifted at an outreach of 35m with the counterweight disconnected to accommodate the congested site requirements. After slewing the panel above the roof in line with the installation position, the counterweight was connected so the crane could boom out to 117.5m with sufficient capacity. Each panel was then safely lowered down to enable easy alignment for further securing. Additionally, six mobile cranes - ranging in capacity from 50t to 350t - were deployed for the installation of various structures at the Expo site, including bridge portals and the public spaces in concourses and arrival plazas.
