MBX-211 |
Microwave type |
|
Detecting accuracy is high because of geometrical setting system |
Feature
- This is a microwave overhead traveling close crane warning device. Consisting of two sets of transmitter/receiver
installed oppositely, when two cranes approach each other until the both detecting areas overlap, the microwave of the opposite side is mutually detected, and an alarm signal is executed.
