Title:
COVER OPENING AND CLOSING DEVICE OF WORK VEHICLE
Document Type and Number:
Japanese Patent JP2019127206
Kind Code:
A
Abstract:
To provide a cover opening and closing device of a work vehicle capable of reliably performing rising actuation of a cover while suppressing a load of a motor or the like at a cover stop position.SOLUTION: A canopy opening and closing device includes an actuator which drives a canopy, a microcomputer which controls drive of a motor of the actuator and an electric current detection circuit which detects an actuation electric current of the motor and performs inputting to the microcomputer. The microcomputer compares the actuation electric current of the motor with a third threshold (S2), stops the motor (S4) when the actuation electric current exceeds a first threshold (Yes at S3) during a period from when the drive of a motor starts to when the actuation electric current becomes lower than the third threshold (Yes at S2) and stops the motor (S8) when the actuation electric current exceeds a second threshold (Yes at S7) after the actuation electric current becomes lower than the third threshold (No at S2).SELECTED DRAWING: Figure 9
