I've never seen a platter before and I see Lift Engineering built a few.

Platter Pull:
POMA Lift:
Differences:
The Platter Pull is a fixed grip style surface lift very similar to a J-Bar or a T-Bar but instead of using a bar at the end of the shaft coming down from the grip it has a circular platter attached to it. Being fixed-grips these lifts normally turn somewhere between 300 and 500 fpm.
The POMA lift is a detachable version of the Platter Pull, using the same circular disk/platter just with the ability to detach from the cable. When you use a POMA lift all of the disks are at the bottom when not in use (unless they are on the return from the top station). The attendant gives you a platter and you put it between your legs. The attendant then pulls a lever which releases the platter's grip onto the cable. About 1 to 2 seconds later you are jolted ahead travelling up the hill somewhere between 600 to 800 fpm. The reason it is called a POMA is because Jean Pomagalski (not sure if I spelled that right) was the original inventor of the POMA lift.

Jonni any idea where the pic of the Poma detach came from ??? We have 1 circa 1960, 1961 same exact lift and let me tell you set it on 6 and you,ll break someone's back.... 0 to 600 to 800 fpm in about 1 second. We also have a fixed for sale... Real cheap belt driven... Ran all year no problems...
They say a monkey can turn a wrench... I hope it's an adjustable....

SRRY.. 2 say no problems would be a lie... LOL ... Wand's stick, top operator's sometime's forget there is a stop gate or on such a lift a top stop.... Broken brittle bars and broken cut wire's due 2 a guest thinkin they can surf this lift 2 the top... All in all no Big trouble really....

Pomagalski is spelled right.
There's no switch that the lift attendent pulls. (Or at least in the case of Storm King.) It should be noted that high-speed pomalifts are not detachable at all. The cable runs through the grip. As you move foward, the grip gets friction from the angle of the pole, and suddenly takes off. The grip rotates with the pole angle of the pole, so if the pole is not perpendicular to the rope, it will catch the rope, and pull. If you get the pole perpendicular to the rope, and the cable does not have any angle change, then you will have lost contact with the rope, and it will just slide.
Here you can see the rope running through the platter "eyes".

Actually, I think there is a button on the controls outside. It is labeled "Launch." However, I think that button is the manual way to launch the platters. I think what you described is true. On less busy days, I believe the lifty can launch some platters so there aren't too many at the bottom.

The only reason to use the 'manual launch' feature is when the auto-launch system doesn't work or if a rider doesn't follow the red light/green light launch system and skis down the ramp early. It doesn't matter how many sticks are in the rack, one or eighty, it's all the same. FYI, the platter grips are called 'buttons', not eyes.
This one was built in 1985.

You are correct they are called buttons, that which the rope runs through.
There were many Versions that were made but they all operated on the same principle.
The early versions had a manual lever that was pulled down by the operator this in turn by mechanical linkage pushed down the arm that was riveted to the button. The button had slots cut into them that when the arm was pushed down contacted the rope at that time the operator if he was good would pull the person forward, this action along with the spring in the hanger tube reduced the shock or snap of the launch to the skier.
Later versions did have a wand and for that matter could have had a photo eye. But it still operated on the same principle.
In this case it was considered a fully automatic loading system.
The light would tell you when to go and the skier would slide down the ramp (to closer match the rope speed, and take the operator out of the system) they would then go through a wand that electrically tripped a solenoid the pushed down the actuator arm that rotated the button into contact with the rope.
This whole system operated on friction the weight alone of the hanger would keep the button in position of contact with the rope.
Once launched the hanger would make a trip up around the return bullwheel and back to the bottom. The hanger would then come into the rack and by mechanical means the trip arm would be raised and the button would lose contact with the rope.
In the rack the button would then slide down to a waiting position until it got back to the front where it would be launched again.
These lifts were great on a cold windy day, but they were a maintenance nightmare.
Buttons wore out, when this happened sometimes they would not trip and or lose friction some where up the hill and slide back into the next person coming up the hill, hanger tubes got dented or bent the slide rack wore out and grease was everywhere, they were also hard on haul ropes.
The larger systems were an AC drum controlled motor, and generally had a floating bullwheel at the return.
The best part of them was as kids and on the racing team you got to know the operators and they would allow you the just stand in position they would trip the launch arm and on a cold morning you could catch 50 or 60 feet of air before touching down and while riding up the line you could pull yourself forward and stop yourself and again catch air. Some days The first 4 to 8 kids of the team in line would plant their ski poles in the center of the track as they were going up the line and the rest of us would use them a slalom gates, the last person in line would pick them up and bring them to the top. AAAH the good old days.

The automatic launching feature must be something that was installed on newer Poma lifts. The Poma lift that I have been mostly in contact with (the one I ride the most) is the Burke Mountain Poma (ca. 1956) which the buttons are manually launched by the attendant. Still a fun ride all the same!

Not to mention when the inner spring has had enough and retires... at 30 feet long. I've thought sometimes that ours takes more TLC than our detachable chairlifts. Ours also has a fixed return with hydraulic tension.

I recall being five or six and riding the old platter at White Pass. there was a span several towers up that was way too high for my rather lightweight self to pull the rope down, and I'd float along for a bit before touching back down. Needless to say all the kids my size loved it. that one was also an operator-released launch system; I heard stories of the ops releasing the bindings of people they didn't like at the same time they released the sticks

The upper snowdon poma or poma 2 at killington is manually operated with a lever. Hella fun to ride and op. If you are ever there ask the attendent to launch you! Depending on your weight you can get a good 5-15ft of airtime.

What a contraption!! Sounds like fun!! Our single-speed Hall can launch people. I got launched off of it one day!
