Following the successful market launch of the Boom Booster kit for the Terex 8800-1 crawler crane, Terex Cranes is now offering a Boom Booster for the crane’s smaller sibling, the Superlift 3800.
It increases the main boom’s stiffness, boosting the crane’s lifting capacity by up to 30 per cent. The welded steel structure consists of seven sections with a length of 12 m, comes with the Terex fall protection system as standard, and is designed for being directly mounted on the crane.
“When equipped with the Boom Booster kit, the Superlift 3800 crane can reach an impressive maximum hook height of 174 m and lift loads of up to 80 tonnes,” explains a company spokesman.
“This means that this cost-effective crane is effectively raising the bar for its lifting capacity class worldwide, as the Boom Booster kit enables it to handle lifts that would otherwise be the exclusive domain of cranes in the 750-tonne class. These parameters make this multifunctional crane especially well-suited to erecting large wind turbines, which usually require lifting heights of more than 140 m.”
Boom Booster kits for Superlift 3800 cranes are available in lengths of 24 to 84 m. Terex Cranes has developed an entire series of innovative solutions designed to provide cost-effective use of the Boom Booster kit, says the spokesman.
“For example, the structure has an overall width of only 3.5 m, making it easy to transport. Two additional boom sections can “slide” into the Boom Booster kit during transportation, eliminating the need for at least one truck that would otherwise be required, providing savings of up to €1,000 ($1,120), depending on the configuration,” he adds.
Another highlight is the optionally available Superlift Split Tray with quick coupling technology, which can be used when setting up the main boom with or without the Boom Booster kit: Once the main boom is set up, the counterweight that is no longer required can easily be uncoupled, after which the crane can move with only the superlift counterweight that is still needed. The Split Tray reduces the amount of assembly time and personnel required and eliminates the need for an assist crane for this particular procedure, making it possible to reduce costs by up to €10,000 ($11,200) per lift according to calculations by Terex.
In addition, a 3.5-m-long extension for the superlift mast enables an increase to the superlift radius from 19 to 21 m and allows to lift off long boom systems from the ground without an assist crane. Finally, the optional Flex Frame solution, which replaces the usual tele-cylinder, allows easy setting of the superlift counterweight radius from 13 to 21 m with full counterweight on the tray. This reduces the need of restacking counterweight, saving valuable time. All three options – superlift mast extension, Split Tray and Flex Frame – are available separately.
