A notification device is used in a moving device and comprises a main unit that can move a moving body by a driving force of a motor and a control unit that controls the motor in response to an operation input. The notification device comprises an operation information acquisition unit that acquires operation information of the motor from the control unit and a notification unit that, when the motor is in operation, makes a notification different from a notification at the time when the motor is stopped.

The present invention relates to a swivel for reducing torsion in a cable, having two swivel parts which are rotatable with respect to one another in the longitudinal direction of the cable, wherein a rotary drive for the forced turning of the two parts with respect to one another is provided. According to the invention, provision is made on the swivel of at least one direction-of-rotation sensor for sensing the direction of torsion of the cable with respect to the swivel, wherein the rotary drive is actuable by a control device, depending on the determined direction of torsion, such that the swivel part connected to the cable is turned in the direction of the sensed direction of torsion.

A system for identifying an operator and managing access rights in connection with a crane (1-100). The crane includes control system (1-110) and a controller (1-200) positioned at a distance from it. The control system maintains a plurality of operator-specific parameters that define operator rights. An identifier reader (1-300) is placed in connection with the controller (1-200) for reading the operator's identifier (1-350) by using a first connection (1-360). A second connection (1-260) is set up between the identifier reader (1-300) and the control system (1-110) to send the operator's identifier (1-350), or information derived from it, to the control system (1-110). The control system (1-110) compares the operations requested through the controller (1-200) with the operator-specific parameters, which define operator rights, and allows the operation of the crane (1-100) only within the scope of rights associated with the operator's identifier (1-350).
摘要:
The present invention relates to a crane [1], in particular in the form of a mobile fast-erecting crane, comprising cabling and a testing device for testing at least one cable [6] of the cabling for sufficient strength, and to a method for testing the cabling of such a crane, wherein a testing tensile force is applied to at least one cable, in particular the trolley cable. According to the invention, a testing tensile force is applied to the cable [6] by a cable tensioning device [7], which is operated in a testing mode when the cable is installed on the crane [1] but before the crane operation is enabled.

A hoist life calculating device has a load calculating unit (21) that calculates a load suspended from a hoist (4) from the motor speed and the current value of a control inverter for the hoist, an operation cycle measuring unit (25) that counts both the number of lifting operations and the number of lowering operations of the hoist for each load calculated by the load calculating unit (21), an operating time measuring unit (24) that counts the operating time for each load calculated by the load calculating unit (21), and a remaining lifetime calculating unit (26) that calculates a loading rate from the operating time for each load measured by the operating time measuring unit (24) and that calculates the remaining lifetime of the device for hoisting from the obtained loading rate.
摘要:
A crane operation assistance system includes: a scanning-type distance meter capable of measuring a distance and an angle between the distance meter and an object under a range of movement of a movable body that can hoist a container and move in a horizontal direction; and object height distribution data making means for making, based on the information measured by the distance meter, object height distribution data that is data indicating a distribution of heights of objects under the range of movement of the movable body. If a blind spot for the distance meter has occurred, the object height distribution data making means revises data of object heights in the zone of the blind spot based on data of an object height at a point that is farthest from the distance meter in a imaginary containers presence zone having an overlap with the zone of the blind spot.
