    • A process for anti-sway control of a rotating boom or other three-degree-of-freedom crane wherein the load is hoisted, at variable hoist lengths, by a cable suspended from a point that can be moved in space in three dimensions, either freely, or under known constraints. Initial acceleration of the load induces an initial sway to the load. A second lateral acceleration, equal to the first lateral acceleration, is scheduled to be applied one-half a sway period later to remove the sway induced by the first acceleration. A third acceleration is applied to correct for half the excess sway induced by hoisting, by non-linearities in the pendulum, and by crane platform motion; and a forth acceleration, of equal magnitude as the third but in the opposite direction, is scheduled for one-half a sway period later, to correct the remaining half of the excess sway energy. The first and third accelerations are constrained by the ability of the crane to execute them and to execute the delayed second and fourth accelerations. The lateral accelerations are applied additively, and repeated sequentially at a variable rate, to accelerate the load from its initial location to objective velocities and locations under controlled anti-sway conditions.

    • The invention relates to a method for damping the load swing of a crane during the traversing motion of a load-carrying trolley and/or a trolley-carrying bridge. The method comprises determining substantially continuously the acceleration of the trolley/bridge and the instantaneous swing time constant, swing velocity (v) and deviation (s) from equilibrium of the pendulum formed by the load. When the velocity reference changes, the acceleration providing the desired change in velocity is determined, said acceleration being switched on immediately, and the acceleration compensating for the swing prevailing at the moment of change of the velocity reference is determined, said acceleration being switched on either immediately or, if the compensating acceleration exceeds the maximum acceleration permissible to the traversing drive when switched on immediately, when the pendulum formed by the load has reached its extreme position.

    • A system and method for eliminating swing motions in gantry-style cranes while subject to operator control is presented. The present invention comprises an infinite impulse response ("IIR") filter and a proportional-integral ("PI") feedback controller (50). The IIR filter receives input signals (46) (commanded velocity or acceleration) from an operator input device (45) and transforms them into output signals (47) in such a fashion that the resulting motion is swing free (i.e., end-point swinging prevented). The parameters of the IIR filter are updated in real time using measurements from a hoist cable length encoder (25). The PI feedback controller compensates for modeling errors and external disturbances, such as wind or perturbations caused by collision with objects. The PI feedback controller operates on cable swing angle measurements provided by a cable angle sensor (27). The present invention adjusts acceleration and deceleration to eliminate oscillations. An especially important feature of the present invention is that it compensates for variable-length cable motions from multiple cables attached to a suspended payload.

    • A control system which stabilizes the hoisting rope of a suspension crane comprising a travel drive control unit capable of calculating a torque reference signal by a speed regulating controller having a proportional gain and an integrator or only a proportional gain on the basis of the deviation of a speed detection signal representing the rotating speed of a traveling motor for driving the trolley of the crane from a speed reference signal obtained by subtracting a damping control speed reference correction signal which is obtained by adding a damping factor to a swing angle calculated on the basis of the speed detection signal representing the rotating speed of the traveling motor or a calculated load torque on the traveling motor from a speed reference signal provided through a linear acceleration starter device by a speed reference device, of controlling the rotating speed of the traveling motor according to the torque reference signal, and of producing a damping effect for damping the oscillation of the hoisting rope through the output drive shaft of the traveling motor; a hoist motor for hoisting the hoist load; and a hoist motor drive control unit. The control system suppresses the oscillation of the hoisting rope resulting from the acceleration and deceleration of the trolley, enabling the trolley to travel at a relatively high speed and further enabling the automatic operation of the crane.

    • A method and device is adapted for controlling rotation of an upper rotary body of a construction machine, the upper rotary body being rotatably mounted on a lower body of the construction machine for lifting a load from a predetermined position thereof. The control is executed by determining, based on the radius of rotation of the lifted load, the weight of the lifted load, the inertia moment of the upper rotary body and the permissible weight of the upper rotary body, a permissible condition not to generate a lateral bending force beyond the lateral bending strength of the upper rotary body, and braking the rotation of the upper rotary body at a rotational angular acceleration satisfying the permissible condition and assuring no-swing of the lifted load. A device is adapted for calculating an inclination angle of the upper rotary body. The calculation is executed by detecting and storing inclination angles of the lower body with respect to two different directions respectively, or detecting and storing inclination angles of the upper rotary body with respect to two different directions respectively when the upper rotary body is at a predetermined reference rotational angle, or detecting and storing inclination angles of the upper rotary body with respect to one direction when the upper rotary body is at two different predetermined reference rotational angles.
