Title:
WORK MACHINE
Document Type and Number:
WIPO Patent Application WO/2021/064775
Kind Code:
A1
Abstract:
The present invention provides a work machine with which deterioration in work efficiency can be suppressed while lowering the possibility of coming into contact with a worker, a dump truck, or the like. A motion range of the work machine is set beforehand such that a worker, a dump truck, or the like is not allowed to enter inside the set motion range. While the work machine performs a stopping control with a margin from an obstacle that has entered the motion range, the stopping control is performed comparatively without a margin with respect to the motion range (the amount of margin is minimized) and, therefore, the frequency of stopping the vehicle body or the work implement can be reduced and deterioration in work efficiency can be suppressed. Additionally, when a worker, a dump truck, or the like has entered the motion range of said work machine, the stopping control is performed with a margin with respect to the vehicle body or the work implement and therefore the possibility of coming into contact with a worker, a dump truck, or the like can be reduced.
