Depends, we do startup for the operators, so yes, it's just a start button & their log sheet.
When we get there in the morning... let's see I'll describe Paradise. Bottom Station: Clean off carriage test two normal stops, slow and E-Stop buttons & visual lift line. Inspect counterweight, make sure it moves freely. In electrical room at top: Turn on Main disconnect switch, turn on drive disconnect switch, turn on control power & turn off gearbox heater. Reset Rollback/OverSpeed/Safety gate. In operator room: Reset Towers/Bottom Station/Service Stop 1, 2 and slow. Go up into drive room & pump E-Brake off to 1400 psi, make sure there is oil in the gearbox. Go back to operator room & reset Top terminal. Visual lift line. Start lift @ 15/20% for warmup - let lift run for about 5 mins. Inspect rollback/overspeed equipment for abnormalities, go into the motor room and inspect the electric motor for arcing brushes and weird noises from the gearbox, as well as oil flowing. Also check service brake clearances/pads. Speed up lift to 100%, let lift run for 5 mins again. Do stopping distance check. Less that 6.9 meters? Good. More than 6.9 - go back into drive room and adjust service brake to under 6.9m. Test all stop/slow buttons. Go back into the drive room, check auxiliary fluids. Start auxiliary & run it to temp. Every two weeks run the lift on auxiliary. Inspect carriers for abnormalities by stopping 10 chairs in the terminal and looking them over.
There's probably something I'm forgetting since it's just become a routine :)

Dang that's a lot of work. Must be a hassel to check all this stuff and keep going up into the motor room. I wonder on high-speed lifts if the computers do all the work. I mean they are so high-tech that they probably calculate fluid levels and stuff for you.

It just seems kind of a hassel to keep climbing up into the drive room over and over again to keep on checking stuff. That's what I kind of mean. It's not a lot of work, but just a lot of repititoin.
BTW Allan, what time do you get up in the morning to start your day.

Typical startup on the Flyer:
-Turn on 24 VDC control power.
-Reset the computer and begin hitting stops. The main PC will record all stops and you can see on the screen what you've hit/missed.
-Unlock motor room; turn off heat; turn on ventilation fan and open vents; turn on 480 VAC main breakers (x 2); hit all motor room stops; check diesel fluid levels; look for leaks from any fluid system (brakes, gearbox, diesel); look for bolts on the floor.
-Go back upstairs into the terminal. Thump all tyres (fill/change any flat ones); look at belts and note any twisted or broken ones, change or untwist any of those; trip all cable protection/position switches; look for leaks in the cadencing gearboxes. Fall down ladder because you're in a hurry.
-Return to lift shack. Bandage cuts and scrapes from falling down ladder. Look at PC screen to ensure all stops register. Curse upon finding that you've missed one. Check it again. Now it registers. (If it still doesn't, note it down and fix it later after you've shuttled operators up.) Wait for bottom operators to call and check all their stops.
-Pump up e-brakes. This will take some time; read War and Peace while pumping.
-Finally- start lift on slow speed and run it for five-six chair lengths. Move to full speed. Check stopping distance after line is cleared of all early morning passengers (lifties for other lifts, patrol, on-mountain restaurant staff, ski school 'clinics' (actually first track poachers, but who's checking?
) This will also take time; continue with Crime and Punishment.
-Check cadence zones by setting a 'test zone' on the PC touch screen; ensure lift stops before a second chair enters zone. Finish coffee and find something else to do.
With several variations on the theme, this is detachable startup at Copper.
Oh- once a week run everyone up on diesel, and once a month operate the lift all day on diesel. Be sure to check fuel status before the all-day operation...

to start up a Poma Detachable
1.turn the control power switch to on and select the desired operationg mode.
2.If the electrical mode is selected, make sure that the main circuit breaker is in the on position. Make sure Aux. Coupling is un coupled.
3. If the aux. position is selected, make sure that the main circuit breaker is in the off position. Make sure Aux coupling is coupled and that the aux engine is operationg correctly. Make sure the siding door on the fron of the terminal and the louvers or windows on the rear of the building are open.
4. Push the RESET buttom
5.check the annunciator and see which faults are displayed
6.Pump the e-brakes until this fault is cleared
7.Clear the remaining faults.
8.The green ligh incorporated in the reset botton will come on indicating that the safeties are ok.
9.Pusah and hold the start button for the duration of the starting bell signal. The lift will start up @ the preset speed.
10.When the drive is started. The dc motor current meter will jump to approximately 50 to 70% of the motors rated current. if howerver after 2-5 seconds the motor current is not down below 25 to 30% of its rated value stop the drive and call maintenance personnel. The drive may be pulling to much current due to frozen sheaces, buried carriers, etc.
11.if icing has occurred on the detachable lift the lift should be brought up to full speed asap to shock ice from the grips.
12. preset the slow and fast speeds to the desired speeds for operation.
13.with the lift running @ it's normal speed, stop the lift @ all stations to determine that all safeties are working correctly.
14.To shutdown the lift, execute a normal stop and turn the control power switch to the off position.
15.Whenever the lift has stopped, the operator must determine the cause and communicate the cause to all attendants on the lift before a restart is initiated.

We're describing a normal day. If it snows lots: clear path for carriers at both ends. Climb onto YAN carriages and clean them with your crotch by shimmying across them. Clean off the bullwheels. Rime day: Go to the top, quickly start/stop lift several times to try and make all the sheaves turn. Well that didn't work - go out and beat on the 61/64 sheaves that are frozen, and then listen to people complain about the funny noises they are making from the ice.
There's more too... Ride the lift up/down and check all towers for alignment ignore the ones that are chronic problems until the summer, listen to people say "you're going the wrong way!" Climb all towers and knock the snow off, listen to the 1000 people going underneath saying "don't jump, your life is worth more than that". Is the counterweight too low? Raise it with the HAND winch, swear at the 12000 kg weight you are rising with your HANDS, then remember it's only 3000 kgs, as it goes through a 4 part reeving system.

And they think they're being funny when they say that...
I'm glad I don't have any icing problems to deal with. All I've got is terminals that fill with snow because there's no underskin to keep it out. But at least you can clean out snow relatively easily.
Total startup time, including checking stops, runs me about an hour. School busses, on the other hand, take about fifteen minutes including warming up the engine on cold mornings.

We do a 30 min APU run on our lifts as a monthly. That must suck to run them once a week and all day as a montly.
