WORK MACHINE
Document Type and Number:
Japanese Patent JP2022148741
Kind Code:
A
Abstract:
To provide a work machine which can secure a wide work space even when an uninvadable surface is set, and can improve work efficiency.SOLUTION: A work machine includes: a vehicle body having a traveling body and a turning body turnably provided on the traveling body; a work device mounted on the turning body; a position attitude detection device for detecting position attitude information on the turning body and the work device; a control device for restricting operation of the turning body or the work device so as to prevent the work device from entering an uninvadable surface set to an upper part of the vehicle body, on the basis of a detection result of the position attitude detection device; and an input device for allowing an operator to perform setting operation of the uninvadable surface. The control device sets a fan-shaped surface orthogonal to a turning central axis of the turning body as an uninvadable surface to the upper part of the vehicle body, and restricts operation of the turning body or the work device so as to prevent the work device from entering the fan-shaped surface, on the basis of the input information input from the input device and the detection result of the position attitude detection device.SELECTED DRAWING: Figure 6
