pumps with pilot control and capacity regulation, electric
controlled oil cooler as standard feature

• Standard high-efficient noise abatment of the diesel-hydraulic

crane drive

oviform boom profile

• 7-section, 72 m long telescopic boom and 12.2 m – 22 m

long biparted swing-away jib extendable to 29 m and 36 m

• One intermediate section of 7 m for the extension of the

telescopic boom at operation with swing-away jib

• Telescopic boom with rounded, oviform bottom shell, thus

high lateral stability

• Optimal utilization of the telescopic boom due to a multitude

of telescoping variants

• Swing-away jib mountable at 0°, 22.5° and 45°, hydraulic

fitting aid, hydraulic ram for continuous variation of the
swing-away jib from 0° - 45° (optional)

• Luffing under load (interpolation of the loads)
• Erection jib 5.3 m long, integrated in swing-away jib
• Easy and quick re-reeving of the hoist rope by rope dead

end connection

• Load hook with rope dead end connection, cylindrical shape

of the load hook for easy displacement by rolling on the
ground
