LUFFING ANGLE MEASUREMENT SYSTEM |
摘要 |
The luffing angle measurement system includes a non-contact distance measuring device mounted on the nose section of a first boom. The non-contact distance measuring device measures either a distance to a second boom pivotally connected to the first boom or measures a time delay between the transmission of electromagnetic energy towards the second boom and reception of electromagnetic energy reflected from the second boom. A controller then converts the measured distance or the measured time delay into a luffing angle.
