The Boom Booster system, developed by Terex with input from Sarens, increases the lifting power of the 1,600t Terex CC 8800-1 crawler cranes with a redeveloped boom component.
The Boom Booster replaces the bottom part of a standard CC 8800-1 boom, increasing capacity by 60% or more at short radii and long boom lengths, by reducing lateral deflection of the boom.
The system consists of five inserts and two adapters, with a total length of 72m and weighing 197t. The constructed Boom Booster is 10m wide and 3.2m high.
Constructed from assemblies of single girders and lacings with pinned connections, the parts can be stored in transport racks and shipped in ten 40ft containers.
Sarens owns two Boom Boosters, to fit the company’s six CC 8800-1 cranes. One CC 8800-1 with Boom Booster is now working at a project to erect 38 wind turbines for Enercon at Noordoostpolder in the Netherlands. The second is working at the Sadara Project in Jubail, Saudi Arabia, completing a lift of a 85m-high, 800t column, with a second column lift due to take place at the end of 2014.
