How does a sky lift work?

How do ski chairlifts work?
A chair lift is made up of two stations, one departure and one arrival, as well as pylons, a load-bearing cable, and chairs. Each chair is equipped with a “grip” that pinches the cable. Then, when the lift is in operation, the cable is pulled along by the motor in the station and the chairs are moved along the line.
Do chairlifts ever break?
There have been two chairlift malfunction incidents in Colorado resulting in fatalities. In 1985, two people were killed in Keystone due to a welding failure on the lift's bullwheel, and in 1976 in Vail cable wires became entangled with a gondola, resulting in the deaths of four people.
How do chairlifts slow down?
They use grips to clamp onto the cable, which then moves them up the mountain. This allows the chair to slow down for loading and unloading by loosening the grip on the cable (also called rope). Because of the more stable design, detachable lifts can move at faster speeds.

The significance of detachable chairlift technology is primarily the speed and capacity. Detachable chairlifts move far faster than their fixed-grip brethren, averaging 1,000 feet per minute (11.3 mph, 18 km/h, 5.08 m/s) versus a typical fixed-grip speed of 500 ft/min (5.6 mph, 9 km/h, 2.54 m/s).

Modern ski lifts rely on electric motors to turn the bull wheels. Most also have secondary backup diesel power motors too - for safety. Electric motors are less expensive to operate than the diesel systems. The power and motor may be located at the top or bottom of the chair lift depending on engineering requirements.
How do ski lifts stay balanced?
There's a motor, of course, but it alone can't simply lug the car up as dead weight, so each cabin going up is counterbalanced by one going down. This is done by mounting each one halfway around a loop of steel cable.
