摘要： PURPOSE:To prevent the contact between cranes or with an obstacle by connecting the local control units of a plurality of tower cranes, adapter unit at a site, and a computer in a management room by the optical cables. CONSTITUTION:The local control units 2a-2c of a plurality of tower cranes 1a-1c detect each crane position from the signals of the hoist detectors 3a-3c, turn-down detectors 4a-4c, turn detectors 5a-5c and send each position data into a computer 20 in a management room 7 through an optical cable 9 and a local adapter unit 8a. In the computer 20, each signal is calculation-processed, and when the contact between the cranes or with an obstacle is afraid of, a signal is sent into the collision preventive interface panels 6a-6c of the pertinent crane, and an alarm is sent to an operator by voice and lamp, and at the same time, the crane is automatically deceleration-stopped. Thus, the safe operation of the crane can be secured.

摘要： PURPOSE:To avoid the collision between a cable crane bucket and a cart and to stop the cart with the shortest safety distance from the bucket, by using a computer to calculate accurately the distance from a start point. CONSTITUTION:A cart 1 is driven automatically between a batcher plant 31 and a point S. A computer (not shown in figure) detects the coordinates of the point S and recognizes and stores a stop point beta supplied for stop at a spot front of the point S as a distance from the plant 31. While the cart 1 receives the deceleration signal from the computer at an instant when it passes through a set deceleration start point alpha and starts its deceleration. Then the cart 1 stops by sensing the stop signal sent from the computer at an instant when the cart 1 reaches the point beta. The cart 1 detects the arrival of a bucket 32 hanged down from a cable crane and then starts again at a low speed to approach slowly to the bucket 32. Then the cart 1 stops at an instant when it touches the bucket 32 and discharges the concrete.

摘要： PROBLEM TO BE SOLVED: To provide a swing prevention control method and a swing prevention control system for a crane, excellent in effect of suppressing swing of a suspended cargo at a turning end point, including swing in a radial direction.
SOLUTION: A jib is turned at a constant turning radius, in the order of an acceleration section, a constant speed section, and a deceleration section. Operating times of the acceleration section and the deceleration section are the same, and are set to be approximately the integral multiple of a cycle To of pendular movement of the suspended cargo. A time difference from an end point of the acceleration section to a point of the first maximum swing displacement by oscillation in the radial direction of the suspended cargo generated by a centrifugal force is "(Δ/2)*To", and an operating time of the constant speed section is set to be "(n+Δ)*To" (n: an integer of 0 or more).

摘要： PROBLEM TO BE SOLVED: To estimate, during acceleration or deceleration, the amount of oscillation of a hanging load such as a bucket hanging from a traversing trolley, on condition that the oscillation of the hanging load can be halted in a minimum time. SOLUTION: The traversing trolley 8 is continuously accelerated or decelerated at a constant rate of acceleration or deceleration along a secondary function curve of its speed to the distance traveled, and respective equations of motion are applied to the traversing trolley 8 and the bucket 18 on condition that the acceleration or deceleration is completed in accordance with one cycle time of the pendulum motion of the bucket 18 caused at the start of acceleration and deceleration of the traversing trolley 8. With the acceleration and deceleration and the pendulum length as given conditions, the amount of oscillation of the bucket 18 is estimated from the time-based positional relationship between the traversing trolley 8 and the bucket 18.
