Abstract (en)
[origin: EP1221426A2] A crane safety device comprising a plurality of wind speed and direction sensors (53) and a control console (48) to display this information and to limit the operation of the crane to safe conditions. Other sensors for boom length (68) etc. are used to evaluate safe conditions. The wind sensor is pivoted and has a counterweight (65) to ensure that the sensor remains vertical at all boom angles. A crane control decision network (66) is also disclosed for programming the setup of the crane. <IMAGE>
