Kronos 8020 - series

The Kronos 8020 series is available with option of three different boom lengths.  This is the most power­ful crane in the Kronos range, they are extremely robust and after rigorous testing they have proved their structural superiority.
The 8020 series cranes’ lifting and slewing forces are high throughout the whole operating envelope therefore guaranteeing high efficiency. The 8020 series of cranes comes as standard with a powerful grab and rotator.
Two particular sectors have been especially focused on when developing the Kronos 8020 series of cranes: durability and ergonomics. The booms have passed detailed FEM analyses and demonstrated their enormous strength. The slewing and lifting dampers soften the movements and prevent sharp hydraulic pressure peaks in loading, therefore ex­tending the crane’s service life. The telescopic extension cylinder with hydraulic end-dampening and swing damper for the grab put final touches to the unit.
Kronos 8020 is suitable for mounting on large tractors and forestry trailers, e.g. Kronos 140 N 4WDM and 160 4WDM
