A crane device, comprising:
- a system for determining and providing information concerning wind proximal to the crane device, the system comprises a first detector apparatus for determining a first component of the wind proximal the crane device, and a second detector apparatus for determining a second component of the wind and the position of a portion of said crane device relative to said second component of the wind;
- and
- a display system including a display for displaying wind information comprising the determined components of the wind and the relative position of said portion of said crane device and said wind provided by the system for determining and providing information to an operator of the crane device.
A crane device, comprising:
- a boom;
- system for determining wind direction proximal to the crane device relative to a direction of said boom, said system comprising at least one wind sensor including a wind direction detector for detecting a direction of wind proximal to the crane device, and an apparatus that determines the direction of said boom relative to the determined direction of the wind proximal the crane device;
- and
- a display system including a display for displaying wind information including the direction of the wind relative to the direction of the boom provided by the determining system to an operator of the crane device.
