Abstract
Provided is a construction machine that avoids automatic release of operation restriction involving, for example, sudden acceleration unintended by an operator even when an inclined angle of a vehicle body changes. The construction machine includes a vehicle bodyconfigured to operate, 3D sensors (obstacle detection devices), andthat detect an obstacle present around the vehicle body, an inclined angle determination device (an inclined angle detection device)that detects the inclined angle of the vehicle body, and a vehicle body controller (a controller)having an operation restriction function that performs a restriction control to restrict an operation of the vehicle bodywhen the 3D sensors (the obstacle detection devices), anddetect an obstacle. When the inclined angle of the vehicle bodyexceeds a predetermined threshold while the restriction control is not performed with the operation restriction function, the vehicle body controller (the controller)disables the operation restriction function. When the inclined angle of the vehicle bodyexceeds the predetermined threshold while the restriction control is performed with the operation restriction function, the vehicle body controller (the controller)does not disable the operation restriction function.
