ABSTRACT:
A work area limitation control system for a construction machine which includes a second entrance forbidden area calculating portion which sets a second entrance forbidden area positioned closer to a front device than a first entrance forbidden area. A slowdown control calculating portion calculates distances between two monitoring points and the second and first entrance forbidden areas and modifies operation signals (pilot pressures) depending on the relation of the calculated distances with respect to a slowdown distance.
