Main Components

25 m basic jib with trolley gear. Extensions up to 70 m radius in 2.5 m steps. Slewing frame with one slewing gear, slew bearing with central lubrication unit and slipring system, operator cabin station with control cabinet. Counterjib with hoisting platform and counterweights.

Drive Technique

All drives frequency controlled squirrel cage motors, fully thermal protected. Hoisting winches Hw 845 FU or Hw 875 FU. Automatic re-reeving device (from 2-fall to 4- fall operation). One slewing gear with electrically operated weathervaning device. Automatic windforce compensation controls. Trolley gear.

Electrical Equipment

Multivoltage equipment for supplies from 380 V to 460 V at 50 / 60 cycles. Electronic safety crane controls with bus technology. Incremental absolute encoders for all operating movements. Electronic load measuring device at basic jib section. Multilingual graphic display showing information to operator, both operational and diagnostics.

Safety Devices

Crane is complete with electronic overload protection system. Increased load moment limitation due to automatic hoist speed reduction. Menu guided setting of overload protection system and of all limiters from operators cabin. Working space limiter, anti-collision interface. Trolley rope breakage safety device.

In series with

Teleservice module and wind indicator.
