Zusammenfassung: | The utility model discloses a band-type brake control circuit and a lifting device, a driving module and a band-type brake switch module are adopted to replace a contactor, the driving module and a band-type brake switch are directly controlled by a controller, the problem that the breaking capacity and the service life are reduced due to frequent action of the contactor is avoided, and the safety problem caused by adhesion of contacts of the contactor is avoided. A coil of the contactor does not need to be arranged in the safety loop, so that the installation and maintenance cost is reduced; the voltage conversion module, the band-type brake switch module and the driving module can all adopt miniaturized electronic elements, so that integration and modularization of the band-type brake control circuit can be realized; and the voltage conversion module, the band-type brake switch module and the driving module adopt miniaturized electronic elements, so that no noise is generated during action, and the user exp |
