When the grille 22 needs to be opened, the winch motor is turned on, and the winch motor drives the first drum 210 and the second drum 220 to rotate counterclockwise. At this time, the second drum 220 winds up the wire rope 218, and the wire rope 218 is unwound and released through the second drum 220. The wire rope 218 on the inner side of the second slide rail frame 214 moves downward, and after the second fixed pulley 213 and the first fixed pulley 212 change direction, the wire rope 218 on the inner side of the first slide rail frame 211 also moves downward, so that the lifting rod 216 and the clamping claw 217 move downward together, and then the grille 22 moves downward and is stored in the cab shell 1. Then the glass window 3 is opened, and the driver can stick his head out to communicate with outsiders. Conversely, the winch motor rotates in the opposite direction to close the grille 22.

[0029] When it is necessary to monitor and measure distance with the outside, the telescopic rotating arm 41 and its upper part can be driven to rotate together through the first motor 42, and the gear 433 can be driven to rotate by the transmission motor 432 of the telescopic assembly 43, and the gear 433 is engaged with the long rack 431 for transmission, thereby driving the long rack 431 to move up and down along the guide sleeve 437, and then the inner sliding tube of the telescopic rotating arm 41 is driven up and down by the long rod 436 and the fixed block 435, so that the height of the telescopic rotating arm 41 can be adjusted, and the second rotating arm 45 and its upper part can be driven to rotate together by the second motor 44, and the third rotating arm 46 and the monitor 47 can be driven to rotate together by the third motor 40, and displayed on the LCD screen, so that the camera 48 and the infrared ranging probe 49 can be used to monitor and measure distance at different angles and heights.
