WOLFF-Boost
With the WOLFF-Boost function, the load is allowed to exceed the load torque range specified for the lifting capacities by up to 10%. This is, however, subject to the restriction that hoisting gear and trolley gear must only be moved alternatingly.

Load Data BOOST
Description
Main Components
30 m (98′) basic jib with trolley gear. Extensions up to 80 m (263′) radius in 2.5 m (8′) steps.
Slewing frame with driver’s cabin, control cabinet, two slewing gears, ball race bearing with
central lubrication unit and slipring system. Counterjib with hoisting platform and counterweights.
Drive Technique
All drives frequency controlled squirrel cage motors, fully thermal protected. Hoisting winches Hw 2075 FU or Hw 20110 FU. Two slewing gears with electrically operated weathervaning
device. Automatic windforce compensation controls. Trolley gear.
Electrical Equipment
Multivoltage equipment for supplies of 480 V Y / 277 V 60 Hz. 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.
Tower Elements, Climbing Device
Tower configuration of WOLFF system tower elements. WOLFF slug bolt connection. Detachable hydraulic WOLFF system climbing devices KWH 20.6 and KWH 23.
WOLFF system inner climbing devices KSH 20 and KSH (E) 23.
Cross Frame KR, Mobile Cross Frame KRF
WOLFF cross frames KR can be used with gauge from 6.0 m up to 10.0 m (20′ – 33′). WOLFF cross frames can be modified to KRF.
