摘要： A control device for a work machine on a construction vehicle is provided so that a bucket cylinder is stopped at a target position, with high accuracy achieved in a bucket cylinder length, and with chock held down to a low level. A bucket cylinder length detection section refereces a cylinder length detection table on the basis of a boom angle and a bell crank angle, thereby detecting a bucket cylinder length. A bucket attitude control section controls the bucket cylinder length so that a target position will be reached. Feedback control is performed until a set value which is set short of a target value is reached. After the bucket cylinder length reaches the set value, open loop control is performed until the target value is reached.

摘要： The construction machine includes a propulsion device, the working equipment, and a controller that controls the propulsion device. The controller performs attitude determination of determining whether or not the present attitude of the working equipment corresponds to a predetermined attitude, performs propulsion determination of determining whether or not the present propulsive operation of the propulsion device corresponds to a predetermined propulsive operation performed while performing a predetermined construction task that applies an over load to the working equipment, performs driving force determination of determining whether or not the magnitude of the present propelling force corresponds to a predetermined magnitude at which an over load is applied to the working equipment, and reduces the propelling force outputted from the propulsion device when the results of attitude determination, propulsion determination, and driving force determination are affirmative.
