DETAILED DESCRIPTION OF THE INVENTION

[0051] According to the rope swinging safety system, the rope drum of the crane (1) is fixed in the highest possible fixed end of the rope (2) between a sufficient number of rope supports for lower body (32), which are located on the rear part of the lower body (30) of the device (3), by means of a sufficient number of rope grabbers (7), bolts (8) and flanged nuts (9). The rope support for lower body (32) is in even numbers, each pair positioned perpendicular to each other. Thus, the system can easily adapt to ropes of different thicknesses. Thanks to the positioning in the highest possible fixed end of the rope (2), a vertical view for the designed lifting height is achieved and it is possible to detect the swinging of the rope (2) more accurately.

[0052] According to the rope swinging safety system, a display (11), a decrement button (12) and an increment button (13), which all have a suitable size, are provided on the device (3). Rope swinging value can be decreased by the decrement button (12) and increased by the increment button (13), in terms of angle and/or distance, and the changed values can be displayed on the display (11). In this way, adjustment can be made manually.

[0053] According to the rope swinging safety system, a safe operation light (14) and a safe stop light (15), which all have a suitable size, are provided on the device (3). If the system operates within the adjusted limits, the safe operation light (14) informs the user that the swinging limit is not exceeded and the system is operating correctly. If the limit is exceeded, the lifting operation is not allowed and the safety stop light (15) and the warning light (10) inform the user that the swinging limit has been exceeded, so the lifting cannot be performed.

[0054] According to the rope swinging safety system, a cable communication connector (5) and a connecting cable entry (6) are also provided on the device (3). In this way, a connection to the system is provided by cables, and limit values can be adjusted and controlled. In this case, whether the limit value is exceeded or not is transmitted to the wired controller of the crane, and visual warnings are provided.

[0055] According to the rope swinging safety system, a protective cover for connector (16) is provided on the device (3), wherein the connector is prevented from being damaged by external environmental conditions when communication with cable is not provided.

[0056] According to the rope swinging safety system, the device (3) comprises a joint gasket for body (33) located between the upper body (25) and the lower body (30). The coupling gasket for body (33) is positioned in the gasket groove for lower body (31) which is located on the lower body (30), so that it protects the coupling of the upper body (25) and the lower body (30) from the negative effects of outdoor conditions. The lower body (30) and the upper body (25) are connected to each other by means of a sufficient number of connecting screws for body (34).

[0057] Since the upper connection cover gasket for cable (23) located between the upper body (25) and the upper connection cover for cable (22) is positioned in the gasket groove for upper body (35) provided in the upper part of the upper body (25), the junction point can be protected from the negative effects of outdoor conditions. The upper connection cover for cable (22) is connected to the upper body (25) by means of a sufficient number of upper connection cover screws for cable (24).

[0058] The upper connection cover for cable (22) is made of a transparent material which is completely light-transparent or only the front surface of which is light-transparent. In this way, it is possible to warn the user from a suitable distance via the warning light (10). While the device (3) is operating safely, the safe working light (14) and the warning light (10) are lighted in green. If the device (3) does not allow the lifting operation due to exceeding the limit values, the safety stop light (15) and the warning light (10) are lighted in red. Therefore, according to the colour of the warning light (10), the user can detect from a suitable distance whether the limit values are exceeded, so that he can take precautions.

[0059] The rope swinging safety system, the device (3) has at least one power board (28) for supplying energy from different power sources; at least one communication board (29) for making adjustments by connecting to the system via both wired and wireless communication; at least one sensor board (27) for measuring the swinging of rope in type of angle; and at least one control board (26) which calculates the safe working area and angle values and comprises user buttons and indicators for parameter settings in order to record the limit values, to record the measured values, to compare the measured values with the limit values, and to prevent an incorrect input by the user.

[0060] In the rope swinging safety system, the remote controller (4) provides a wireless access to the device (3). A display for controller (17), a decrement button for controller (18), a confirmation button for controller (19) and an increment button for controller (20), which all have a suitable size, are provided on the controller (4). Limit values and whether the limit values are exceeded or not are provided to the user over the display for controller (17).

[0061] When the setting of the limit values is desired, the angle or distance can be decreased with the control value decrease button (18) and increased with the control value increase button (20), and the appropriate value can be confirmed and recorded with the control confirmation button (19). In case of exceeding the limit values, the user is warned and measures are taken easily.

INDUSTRIAL APPLICATION OF THE INVENTION

[0062] The rope swinging safety system, which brings successful solutions to the technical problems mentioned above, is a product that can be produced like other crane safety parts.
