DOUBLE JIB LEVEL LUFFING

The Double Jib Level Luffing crane is, like the Lemniscate crane, able to move the load in horizontal direction without vertical movement and thus not requiring any lift capacity (and energy) during the horizontal movement. A double boom principle delivers an optimum balance between weight and center of gravity.

The Double Jib Level Luffing crane type is a three boom system: the main jib (front arm), the jib tie (rear arm) and the jib fly (upper arm). The pull- and pressure boom are in a vertical position when the crane is at medium outreach. This contributes to an optimization of the balancing system of the crane.

BENEFITS

• Optimal balance and stability through double boom Lemniscate principle
• Capacity (up to 800t/per hour)
• Outreach of 13m-43m
• Cycles of 180 degrees in 55 sec
• Extreme low center of gravity
• Optimal driver position with full view into the hold
• Almost horizontal load curve during luffing
• Full frequency control

Reliability, durability and client’s requirements are paramount.
