600-TON CRAWLER CRANE IS EASILY TRANSPORTED
The 600-ton, SL6000 crawler crane is a new model at the top end of Kobelco’s range of crawler cranes. The SL6000 features three different configurations: • Standard Crane – 276 feet maximum standard main boom, 354 feet maximum long boom and a luffer option of 197 feet main boom and 236 feet luffing jib. • Heavy Lift Crane (which includes an additional Mast) – 276 feet maximum standard main boom, 354 feet maximum long boom and a luffer option of 217 feet main boom and 236 feet luffing jib. • Super Heavy Lift Crane (which includes HL Mast and an additional 551,400 pounds of palette counterweight) – 276 feet maximum standard boom, 413 feet maximum long boom and a luffer option of 276 feet main boom and 276 feet of luffing jib.
The 1,082-foot square footprint of the SL6000 gives it sure and firm stability throughout the full 360-degree rotation. The SL6000 is powered by a Tier 3 compliant, Hino E13C-UV, 429 hp diesel engine, and has six variable-displacement hydraulic pumps.
As with all the Kobelco cranes, the SL6000 can be broken down into easily-transportable sub-assemblies. The largest individual part being the 9-foot 10-inch wide car-body and upper-structure assembly weighing 141,000 pounds, which itself can be broken down to 91,100 pounds for the upper-structure and 49,900 pounds for the carbody with a quick-connection system. By removing the mast assembly with an ‘easy-attachment’ system, it can be further reduced to 70,600 pounds.
Each fully-assembled crawler-track assembly weighs 88,200 pounds, and the boom and jib sections can be ‘nested’ for transportation. Main winch, auxiliary winch (and optional luffing jib winch) are conveniently located in the lower boom, reducing the transportation weight of the base machine. In order to reduce the assembly time and to further reduce the transportation weight of the base machine, Kobelco designed the SL6000 with the boom winch mounted on the mast and with the boom wire rope already reeved through the sheaves of the upper and lower spreader. Assembly on site can be completed in a staggering two to four days depending on the configuration.
