[0002] In automobile production workshops, the lifting mechanism is widely used to transport workpieces, such as car bodies or automobile interiors. Here, the busbar is a power transmission device that supplies power to the lifting mechanism.

[0039] The local control device 20 can be configured as a control device in various forms, such as a programmable logic controller, etc. The local control device 20 can be arranged at a production line site, and can be assigned to a sling mechanism 10, for example. The local control device 20 can be configured to be communicatively connected to the first temperature sensor 11 via a first communication connection and to be communicatively connected to the second temperature sensor 12 via a second communication connection. Advantageously, the local control device 20 can be configured to receive the temperature of the first motor 21 from the first temperature sensor 11 via the first communication connection, and to receive the temperature of the second motor 22 from the second temperature sensor 12 via the second communication connection.
