Texas Crane Services inaugurated its new GMK7550 all terrain crane with a challenging dam maintenance project in Bastrop County, Texas, USA.
The 550 ton (500 tonne) crane lifted a Grove RT530E-2 rough terrain crane onto a barge to enable it to carry out maintenance work on the dam of the Lake Bastrop reservoir. The 4,000 foot (1220 metre) long, 85 ft (26 m) high earth-filled dam is inaccessible to cranes from land, which is why Texas Crane Services adopted the barge approach.
For the pick, the GMK7550 worked at a 105 ft (32 m) radius. It was configured with 148 ft (45 m) of main boom and used 120 tons (109 tonnes) of counterweight to lift the 30 ton (27 tonne) capacity rough terrain crane.
Once in place on the barge, the Grove RT530E-2 was then transported across the lake to the section of the dam that needed repair. From the barge the RT530E-2 was able to easily replace the stop logs.
