Al Faris deployed a Demag CC 3800-1 lattice boom crawler crane to lift heat recovery steam generators (HRSG) at a power plant in the UAE.

Al Faris installed 16 HRSGs, which measured 28 m long and weighed up to 80 tonnes. According to Tadano, the units had to be brought to a height of just under 60 m at a radius of 40 m so that they could be installed.

To do this, the Al Faris team deployed its Demag CC 3800-1 in an SWSL configuration with a 48 m main boom, a 36 m fly jib, and a superlift counterweight of 165 tonnes with a radius of 11 m.

For the 16 lifts, the 650-tonne capacity crane was assisted by another 250-tonne crawler crane from Al Faris’ fleet, which picked up the HSRGs from one end so that the CC 3800-1 could then bring them to a vertical position. After this, the 250-tonne crane “unhanded” the load and the CC 3800-1 placed it into the desired position.

The project took a total of six months and consisted of transporting and positioning various components including condensers, boilers, generators, tanks, in addition to the HRSG modules. Al Faris used hydraulic trailers and various all-terrain and crawler cranes to complete the works.

Hilary Pinto, Al Faris founder and managing director, said that the biggest challenge was the tight space conditions during set up, conversion and disassembly. “Handling the long boom components in particular really demanded a great deal of our team, but they were able to take care of that smoothly, and not in small part thanks to the crane’s ease of assembly.”
