This Flat Top Luffing Tower Crane can go from horizontal with a 55 meter radius to a minimum radius of three meters in only 90 seconds. The luffing speed is varied by the load sensing hydraulic luffing cylinder.
This near vertical feature is particularly beneficial on crowded job sites. With the jib in this vertical position, the out-of-service radius is less than 10 meters.
It has 12 tonnes lift capacity when dual reeved at 55 meters, and 6 tonnes capacity at 55 meters when single reeved.
