The 1963 Černý Důl – Kunčice nad Labem aerial ropeway is over 8 km (5 mi) long, over 30 m high in places and carries 135 tons of limestone every hour from a quarry to the nearest train station. Its 120kW 3-phase synchronous motor requires power for a few minutes at the start and end of each day when most of the 800kg-capacity trolleys are empty, and spends most of the shift generating mains electricity and acting as a speed governor. Unlike the EV, it is fully autonomous most of the way, only 5 people are required to operate it. (Loading, unloading and timed dispatching is automatic, arriving/leaving carts just need to be checked; a safety latch has to be manually dis/engaged on trolleys passing the check.) The quarry will continue operation as long as it pays off, then the ropeway will be scrapped (projected 2033). A dude illegally rode the way up on it somewhat recently. He could have fallen to his death if he pulled the latch.
There's also one in the UK Tom Scott did a video on.
I know, this one is shorter and has mechanical brakes. Not as great but I imagine the Czech one, one of the largest in Europe, has very few English-language sources that could have pointed it out to him. I don't know whether the Claughton one cannot be ridden or Tom is just squeamish about safety (see description) but the Černý Důl one definitely can, that's how they do routine inspections.
