Abstract
A control section determines a monitoring region, a region wherein an obstacle is to be monitored, the monitoring region not including the lower travelling body. The control section changes the monitoring region so as not to include the lower travelling body based on a turn angle detected by the turn angle detection section. The control section limits operation of at least one of travelling of the lower travelling body and turning of the upper slewing body when the obstacle detection section detects an obstacle being present in the monitoring region.
