Tower crane

The 21 LC 660 tower crane from Linden Comansa is available in four versions, depending on the maximum load — 39,680, 52,910, 79,360 and 105,820 pounds. The crane features the Effi-Plus high-speed hoist mechanism, which allows for hoist speeds up to 800 feet per minute, and the PowerLift system, which improves the load diagram by 10 percent with reduced speeds. The 21 LC 660 is suited for public works, industrial construction, mining and infrastructure applications. www.lindencomansaamerica.com/
