Patent ID: 8660759

Claim:
A traveling crane operation control apparatus for a traveling crane having travel rails laid in a predetermined direction in a horizontal plane, a traverse rail disposed in a direction perpendicular to said travel rails and moved along said travel rails by a travel motor, and an electric hoist having a traverse motor for moving along said traverse rail and an elevation motor for lifting and lowering a load, said traveling crane operation control apparatus comprising: an operation control circuit section including a base unit wearable on an arm of an operator and a control unit operable by a hand of the arm wearing said base unit; said base unit having base unit tilt detecting means detecting a vertical tilt direction and tilt angle of said base unit in a vertical plane, base unit direction detecting means detecting a direction in which said base unit points in a horizontal plane, and command signal generating means generating a travel command signal and a travel speed command signal for said travel motor, a traverse command signal and a traverse speed command signal for said traverse motor, and an elevation command signal and an elevation speed command signal for said elevation motor; said control unit having at least motion decision means outputting a motion decision signal to the command signal generating means of said base unit; wherein, said command signal generating means has the following functions A, B, and C: A. a function of generating the travel command signal and the travel speed command signal, and the traverse command signal and the traverse speed command signal according to a detection signal from said base unit direction detecting means when the operator is pointing the arm wearing said base unit in a direction for movement of said traveling crane in the horizontal plane and when the motion decision signal is output from said motion decision means; B. a function of generating the elevation command signal and the elevation speed command signal according to a detection signal from said base unit tilt detecting means when the operator is pointing the arm wearing said base unit in a vertical direction for lifting or lowering of the load by said electric hoist and when the motion decision signal is output from said motion decision means; and C. a function of generating the elevation command signal and the elevation speed command signal, the travel command signal and the travel speed command signal, and the traverse command signal and the traverse speed command signal according to detection signals from said base unit direction detecting means and said base unit tilt detecting means when the operator is pointing the arm wearing said base unit in a direction for movement of said traveling crane in the horizontal plane and in a vertical direction for lifting or lowering of the load by said electric hoist and when the motion decision signal is output from said motion decision means.
