METHOD FOR CONTROLLING AN ARTICULATED TURNTABLE LADDER OF A RESCUE VEHICLE |
| 摘要 |
The present invention relates to a method for controlling an articulated turntable ladder (12) of a rescue vehicle (10) wherein the ladder (12) comprises a plurality of telescopically extendable ladder parts (14) by including a tip ladder part (18) pivotable around a horizontal first pivot axis (28) by means of a first pivoting drive. The ladder further comprises a cage (22) connected to the free end of the tip ladder part (18) to be pivoted around a second pivot axis (30) by means of a second pivoting drive. The ladder (12) is pivotably mounted to a base part (16) on top of the vehicle (10) by means of a third pivoting drive to be lifted or lowered around a third pivot axis (32). The method provides for the step of controlling the first pivoting drive such that the absolute inclination angle (a) of the tip ladder part (18) is maintained constant during a lifting or lowering movement of the ladder (12) around the third pivot axis (32). |

1. Method for controlling an articulated turntable ladder (12) of a rescue vehicle (10), said ladder (12) comprising a plurality of telescopically extendable ladder parts (14) including a tip ladder part (18) that is connected to the remaining ladder parts (20) to be pivoted around a horizontal first pivot axis (28) by means of a first pivoting drive, and a cage (22) connected to the free end of the tip ladder part (18) to be pivoted around a second pivot axis (30) by means of a second pivoting drive,
said ladder (12) being pivotably mounted to a base part (16) on top of the vehicle (10) by means of a third pivoting drive to be lifted or lowered around a third pivot axis (32), said second pivot axis (30) and said third pivot axis (32) being parallel to said first pivot axis (28), characterized by controlling the first pivoting drive such that the absolute inclination angle (α) of the tip ladder part (18) is maintained constant during a lifting or lowering movement of the ladder (12) around the third pivot axis (32). |
