Metro J.V on the Dubai Metro’s Jumeirah Lake Towers Station in a 140t twin lift of the gantry footbridge.
The LTM1250-6.1 joins the Al Faris Equipment Rentals fleet, one of the largest in the Middle East with more than 250 mobile cranes and including 130 Liebherr models; all fitted with Liccon software ensuring lifts are made safely and economically.
Al Faris Equipment Rentals was formed in Dubai in 1992 to provide rental cranes and transport for the oil and gas industry later extending into oil refineries, power plants and the construction sector.
To date, Al Faris has taken delivery of 22 Liebherr mobile cranes this year and has a further 14 on order including its largest mobile crane, a Liebherr 1200 t capacity LTM11200-9.1.
Illustrated, the LTM1250-6.1 performs a twin lift of the 32m lg x 10m wide x 6m high steel gantry which, once fitted out will become the pedestrian bridge spanning the four lanes of the Sheik Zayed Road at Jumeirah Lakes Station.
Weighing 140t, the gantry was lifted and positioned on ‘stools’ alongside the Sheik Zayed Road for fitting out. Once completed, the bridge will be finally positioned in a hydraulic lift.
The Liebherr LTM 1250-6.1 mobile crane features a 15.5m – 72m telescopic boom and has a maximum lifting capacity of 250t at 3m radius. It also features a 108m maximum lifting height.
The six-axle mobile crane offers improved operating safety in the travel mode and has a top speed of 80km.
On track for operations to begin in 2009, the Dubai Metro is set to be one of the most advanced urban rail systems in the world; and the world’s longest fully automated rail system.
The 52.1 Km (32.5 mile) Red Line will feature 29 stations and run from Jebel Ali to Rashidiya.
Groundworks were started in February 2006. In August a second line, the 17.6 Km Green Line was announced, intersecting the red line at two stations and running from Al Ittihad Square to Rashidiya.
When fully operational, the Dubai Metro has been designed to carry approximately 1.2 million passengers on an average day and 355 million passengers annually.
Main contractor for the Dubai Metro are Mitsubishi Heavy Industries, Obayashi Corp, Kajima Corp and Yapi Merkezi JV.
