Title:
WORK ATTACHMENT STOP CONTROL DEVICE FOR CONSTRUCTION MACHINERY
Document Type and Number:
Japanese Patent JP3895439
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To perform effective deceleration of the movement speed of work attachment.
SOLUTION: This work attachment stop control device is provided with position detecting means 5f, 6f, and 7f to detect the position of work attachment; a first deceleration command value deciding means 12 to decide a first deceleration command value corresponding to the position of the detecting work attachment; a set movement speed calculating means 13 to calculate a set movement speed corresponding to the position of the detecting work attachment; an actual movement speed detecting means 14 to detect the actual movement speed of the work attachment; a movement speed comparing means 15 to compare the set movement speed and the actual movement speed of the work attachment; a second deceleration command value deciding means 16 to decide a second deceleration command value corresponding to a speed differecet between the set movement speed and the actual movement speed, compared with each other; and a deceleration command signal output means 17 to output a deceleration command signal calculated by a composite value of the first and second deceleration command values.
