摘要

An excavator control apparatus for shovel-type construction equipment includes a n automatic digging control section, a digging load control device, and an operation command correcting device. The shovel-type construction equipment has a boom, an arm and a bucket that are successively and rotatably connected in an operation section. The boom, the arm and the bucket ar e each connected to at least one cylinder that extends and retracts according to the operation of a lever. The digging load control device permits an automatic digging routing to be executed by controllin g the extension and retraction of the cylinder. The digging load control device transmits operation commands to the cylinder to maintain a digging load approximately equal to a set digging load du ring automatic digging. The operation commands transmitted to the cylinder by manual operation of the lever without canceling the automatic digging routine.
