Anti-two block device using non-contact measuring and detecting devices |
| 摘要 |
<p>In the anti-two block device, a non-contact measuring device (10) detects in one form or another the distance between a boom nose (60) and a load-bearing member (40) supported thereby. If the distance detected is less than a predetermined threshold value, the device (10) triggers a warning or other operation to assist an operator in preventing anti-two blocking. <IMAGE></p> |
