摘要： PROBLEM TO BE SOLVED: To easily stop in an objective position at deceleration time during coast operation of a crane, smoothly accelerate without increasing load detection at running motor operation time, by improving 35 responsiveness, so that the load deflection can be absorbed by an operator with acceleration/deceleration action. SOLUTION: In an output side to a motor 1 of a crane running drive motor, in a pulse generator 2 of a speed detection means equipped with a mechanical foot brake 30, a pulse frequency in proportion to a rotational speed is output, a speed signal ωr is obtained in a speed arithmetic part 17. On the other hand, a crane running speed is set by a speed setter 3-1, 3-2, 3-3. In a current controller and a PWM inverter part 19, by torque component current It and a magnetic flux component current Im, a level I1 of a primary current of the running motor is vector synthetically calculated, by a primary ouput angular frequency ω1 of the running motor, a primary current of the motor is determined. In the current controller and the PWM inverter part, a speed of the running motor is controlled by pulse width modulation (PWM) control.

CONSTITUTION:First, work 5 is lifted from placed mounts 6 with hoists 11 and 12. Next, the work 5 is made the vertical by winding up one side wire rope 13 and winding down the other side wire rope 14. Then the work 5 us 180 deg.-rotated with an electric rotation hook 30, linked to the wire rope 13, to be stopped. After that, the twist of a sling 81 is released by 180 deg.-rotating an electric rotation hook 31, linked to the wire rope 14, in a reverse direction to the electric rotation hook 30. Finally, the wire rope 14 is wound and inversely the wire rope 13 is rewound with a winding device, etc., 11 to 90 deg.-rotate the work 5 to make it horizontal. At this time, the work 5 is fully reversed at its first position on the placed mounts 6.

摘要： PURPOSE:To obtain the automatic device and improve efficiency by installing a hanger and a hanger housing part on the side part of a loading base and installing a hanger suspending device onto a radio introducing crane, in the captioned device for the long and heavy articles such as steel products. CONSTITUTION:A crane 10 is set over a loading base 1, and a frame 30 is set oppositely to a hanger 6. Then, a cam 25 is turned by a cylinder 26, and an extension rod 21 is extended, and projected from a lower weight piece 29, and projected into the hanger 6. Then, an extension beam 12 is raised, and the hanger 6 is engaged with the extension rod 21. Therefore, a steel material 36 is raised together with the loading base 1. The crane is drive-controlled by a radio introducing device, and transported to a prescribed position. The crane is controlled through a calculation machine, crane controller, and the radio introducing device which are not shown in the figure.

摘要： PURPOSE:To efficiently perform the work by lowering a crane hook to lower a stop-mounting link of bucket hanging tongs, turning this link to stop-mount it to a bucket, winding it up thereafter releasing stop-mounting of a stop- mounting part in one side in the destination and winding up a crane to tilt the bucket. CONSTITUTION:A crane hook 44 is lowered to lower a hook 12 (stop-mounting part) to a bucket 33 provided in bucket hanging tongs 1, and this hook 12 is stop-mounted to stopper levers 38, 38 of the bucket 33, mounting a load, by actuating a motor to rotate this hook 12. After winding up and conveying by a crane, stop-mounting to the stopper lever 38 of the hook 12 in one side is released in the destination, and a conveyed object is released by winding up the crane hook 44 to tilt the bucket 33. Consequently, preliminary work of slinging of the bucket to the crane hook, conveyance, bucket tumbling, resetting the load released bucket, etc., is made possible only by operation of a crane operator.
