HIGHLIGHTS

Kronos 6020

Kronos 6020's powerful slewing device, short lift boom and strong chain transmission based double extensions, together make transportation of heavy loads extremely accurate and fast. 

Hydraulic hoses are well shielded inside a protected cover. The hoses are dimensioned for large amounts of oil flow to the grapple. This enables the efficient use of diversified felling and energy grapples without further modifications.

Kronos 8020

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. 

Kronos 6020/8020 Series

Both the Kronos 6020 & 8020 are suitable for mounting onto large tractors and forestry trailers, for example to the Kronos 140 4WDM & 160 4WDM.

Kronos 6020

There are various alternative control systems for the crane. As a basic choice, a mechanical multi-lever control valve is available but for the professional contractor a hydraulic or electrical remote control system is an advisable alternative. The greatest output in professional use can be reached by a fully electronic CAN bus controlled Parker IQAN system. The system enables among other things, individual speed control of all the motions. 

Kronos 8020

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 fianl touches to the unit. 

SPECIFICATION
