Document Type and Number:
WIPO Patent Application WO/2006/054712
Kind Code:
A1
Abstract:
A control system having a force measurement means (3) for measuring vertical operation force that is force applied by a worker to the lower part of a rope (2) and also measuring the magnitude of force by mass and acceleration of a load; a first control means (4) in which a first calculation section (1) calculates, based on the result of the measurement by the force measurement means (3), the direction of rotation and speed of a servo motor to output a drive command signal to the servo motor; a length measurement means for measuring the length of the rope (2) unwound and suspended from a rope winding drum; a weight measurement means for measuring the weight of the load suspended by the rope (2); an angle measurement means for measuring the angle of swing formed by the rope (2) when the load is horizontally pushed by the worker and a vertical plane; and a second control means in which a second calculation means (7) calculates, based on information on the measurements from the length measurement means, weight measurement means, and angle measurement means, traveling conditions of a crane to output a drive command signal to the crane.
