Title:
HYDRAULIC EXCAVATOR
Document Type and Number:
WIPO Patent Application WO/2020/080293
Kind Code:
A1
Abstract:
A hydraulic excavator is provided in which, even when operating in a situation with moving bodies present around the excavator body, the operator can reliably recognize warnings advising that the seatbelt is unfastened. This controller outputs a first warning through a notification system in the case that moving bodies have been detected and a seatbelt detection device has detected that the seatbelt is fastened, outputs a second warning signal through the notification device in the case that moving bodies have not been detected and the seatbelt detection device has detected that the seatbelt is unfastened, and outputs, with higher priority than the first warning, the second warning through the notification device in the case that moving bodies have been detected and the seatbelt detection device has detected that the seatbelt is unfastened.
