[0014] In an advantageous embodiment, the oscillating circuit is connected to the AC voltage side interface of the AC / DC converter, and the intermediate circuit is connected to the DC voltage side interface of the AC / DC converter.

[0044] As shown, the conveying system, which is preferably designed as a construction hoist, has a particularly vertically oriented cable tray 1 , which is particularly assembled from a plurality of modules, into which the primary conductor is inserted and received, particularly in a vertically elongated manner.
[0045] Therefore, the cable carrier 1, which is configured as an elongated conductor loop, preferably provides an elongated recess in order to place the primary conductor 3, in particular, to place the primary conductor 3 that can be powered by the feeder 2. Here, the feeder 2 applies a medium-frequency alternating current to the primary conductor 3. The frequency of the alternating current is between 10 kHz and 1 MHz, and the feeder 2 acts as a current source.
[0046] The cable tray 1 is realized by modules 20 arranged one behind the other in a row and connected to one another in a form-fitting manner. A tongue and groove system is provided for this purpose.
[0047] Each of these modules has a tongue 21 designed as a tongue and a groove 22 designed as a recess on both sides in the cable direction, into which the corresponding tongue of the nearest module engages. Similarly, the tongue of this module also engages in the corresponding recess of the nearest module.
[0048] The modules are preferably designed to be flat and / or plate-shaped, in particular each as a plastic injection-molded part.
[0049] The cable bracket can thus be easily fastened to a support of a conveyor system, in particular a construction hoist, and can then hold the primary conductor 3 .
[0050] The movable part, which is arranged movably along the support, in particular in the vertical direction as the direction of movement, has one or more secondary windings which are inductively coupled to the primary conductor 3 which is laid in an elongated manner in the cable carrier 1 .
[0051] Preferably, each secondary winding is connected in series or in parallel with a capacitor, so that the resonance frequency of the oscillating circuit formed thereby is equal to the frequency of the alternating current applied to the primary conductor 3. This enables stable transmission of electrical energy while overcoming the distance variation between the primary conductor and the secondary winding.
[0052] The voltage dropped at the oscillating circuit is fed to an AC / DC converter 54 , in particular a rectifier, from which an intermediate circuit, which is formed in particular by the DC voltage line 50 , can then be supplied.
[0053] On the one hand, the electrical consumers 55 are supplied with power from the intermediate circuit, and on the other hand, the energy store 51 and the braking resistor 53 can be connected to the intermediate circuit via an energy management device 52 .
[0054] If the secondary winding can provide enough power, the energy management mechanism 52 releases the load of the energy storage 51 (especially the supercapacitor), and the energy storage 51 is charged. After charging the energy storage 51, the remaining excess power is transmitted to the braking resistor 53, thereby preventing the voltage in the intermediate circuit from exceeding the critical voltage threshold.
[0055] However, if the consumer 55 requires more power than the secondary winding 30 can provide, the energy management device makes the power of the energy store 51 available to the intermediate circuit, while the braking resistor 53 remains switched off.
[0056] The energy storage device 51 can preferably be designed as a supercapacitor and can therefore store large amounts of energy.
[0057] In a further embodiment according to the invention, the module is screwed to a support of the conveying system using bolts. The module 20 is thus fastened to the support. Optionally, the module 20 is additionally glued to the support.
[0058] In another embodiment of the present invention, the primary conductor is arranged to be integrated in the cable tray. Here, each module 20 has a lead conductor section placed in a first groove of the module 20, especially encapsulated with plastic injection molding, and a return conductor section placed in a second groove of the module 20 spaced apart from the first groove and extending parallel to the first groove, especially encapsulated with plastic injection molding.
[0059] At the first end of each module 20, which is located at the front in the direction of movement, a connecting conductor is mounted to the respective module 20, which connecting conductor electrically conductively connects the outgoing conductor section with the return conductor section. The connecting conductor is oriented in a transverse direction relative to the direction of movement of the movable part and is therefore also oriented transversely relative to the direction of extension of the outgoing conductor section and transversely relative to the direction of extension of the return conductor section.
[0060] Each module has only a groove at its first end, which is located at the front in the direction of movement, and only a tongue at its other end, which is located at the rear in the direction of movement.
[0061] As soon as the second module 20 which is most adjacent to the first module is connected by inserting its tongue into the groove of the first module 20, the connecting conductor of the first module 20 is pressed away from the outgoing conductor section and the return conductor section of the first module 20 and is thus electrically isolated from the outgoing conductor section and the return conductor section. For example, the connecting conductor is received and held in the plastic of the module 20. However, if the tongue of the second module 20 is inserted into the groove of the first module 20, the plastic is deformed and acts as a rotating hinge, so that the connecting conductor is spaced apart from the outgoing conductor section and the return conductor section.
