According to accident prevention regulations (UVV, BGV D6 § 14.1 (VBG 9)), cranes<br />
must have their power-driven travelling and slewing movements braked, thus<br />
preventing unint<strong>end</strong>ed movement. According to the regulations UVV 18.2 BGV D6<br />
§ 30.6 (VBG 9), the crane operator must ensure that cranes exposed to the wind are<br />
secured during storms and at the <strong>end</strong> of work.<br />
According to the surface area exposed to the wind, one or two safety catches are<br />
required per crane.<br />
Dep<strong>end</strong>ing on accessibility, the manually operated wind safety catch should be<br />
preferred.<br />
Optimum handling capacity can only be achieved by correctly selecting the working<br />
speeds. For this, the average speed of the individual movements is the determining<br />
factor.<br />
