Схема снижения скорости моста крана в краевой зоне цеха

Proposal to limit the speed of the bridge crane when approaching the marginal zone of the shop. With asynchronous motors with a phase rotor. Near the parking zone of the crane, a boom is installed, which switches the limit switch on the crane bridge to a position that excludes all speeds on the controller, except the minimum one.
