In the inverter hoist, separate relays are connected to each of the up switch and down switch that are connected in parallel to the power source, and the inverter is set in motor operation mode and stop mode by turning on and off of these relays, and
The above-mentioned shield is equipped with a timer that is immediately turned on or delayed cut off when the above-mentioned relay is turned on and the inverter run signal and the above-mentioned relay is turned off. Equipped with a relay that is turned on in response to a fault signal from the inverter due to wire breakage, etc.
An inverter hoist characterized in that when the relay is turned on, contacts connected in series to the up switch and down switch are opened.
