	Lift hill - Wikipedia, the free encyclopedia
		A lift hill, or chain hill, is often the initial upward section of track on a typical roller coaster that initially transports the roller coaster train to an elevated point.
		Lift hills usually propel the train to the top of the ride via one of two methods: a chain lift involving a long, continuous chain which trains hook on to and are carried to the top; or a drive tire system in which multiple motorized tires push the train upwards.
		The familiar "clickity-clack" sound that occurs as roller coaster trains ascend the lift hill is not caused by the chain itself, contrary to popular belief.

		The first modification is at the base of the lift hill, where the gearing ratio has been changed to 24:1, much faster than the 120:1 on the first coaster, but still powerful enough.
		The operator pushes touch sensor 1, and the lift moves up.The lift is some beams connected to a conveyor belt link, which is connected to a chain that continues up to the top of the hill.
		At the top of the hill after the car has been released, the operator pushes touch 1 again, and and the lift mechanism retreats back to the bottom of the hill.

	CEC: Coaster Physics
		The train is carried up to the top of the lift hill by the lift motor, and is from then on "powered" by gravity until it returns to the station (for the sake of simplicity, I will ignore unusual cases such as shuttle loops).
		Similarly, the lift motor of a roller coaster exerts energy to lift the train to the top of the lift hill, energy that will eventually become kinetic energy when the train drops.
		Furthermore, at the bottom of hills, the train will tend to go slower at the end of the ride than it did at the beginning, because to go fast also means having a lot of energy.

	CEC: Coaster Terms
		The sensation of being lifted off your seat when the coaster descends or ascends a hill where the cars are made to follow a curvature that is slightly lower than the curvature they would follow if not held to the tracks.
		As the coaster ascends the lift hill, each dog (which is pivoted) drops into a slot designed to hold the train from rolling backwards into the station, should the chain break.
		Note that some hills are designed to give air time on the way up by using inertia and a track curvature which follows just under the parabolic curve of the train, were the track not there.

		The lift hill uses a new elevator lift lift system which is quite fast and almost required for the very long lift hill.
		The lift hill is at 45 degrees which is steeper than the drops on some coasters.

		As we saw in the last section, the initial lift hill in a roller coaster serves to build up potential energy.
		At the top of the first lift hill (a), there is maximum potential energy because the train is as high as it gets.
		At the bottom of the hill (b), there is maximum kinetic energy and little potential energy.

		The Hill Hiker's typical footing layout is supported by posts that anchor to the outside of the 24-inch-wide track every 10 feet for the entire length of the track.
		The Hill Hiker lift in Belize is powered by a three-phase, three-hp brake motor coupled to a 60 to 1 gearbox.
		The ability to generate the needed electricity from the river to produce enough power to run the lift and the entire lodge is also an example of ingenuity coupled with necessity and common-sense engineering.

		The length of the lift hill inspired Intamin to develop a new lift system that would move the trains to the top faster than the conventional motor-and-chain mechanism.
		With a lift hill and many sections of extreme height it would seem that the new ride would dwarf everything else in the park.
		At the peak of the hill, one has a brief moment to enjoy the sight of the park from this unprecedented vantage point.

		The best lift and sometimes the only spot you can find lift in light winds is produced from wind coming from the east, blowing up the steepest side.
		The hill is shaped like a cone so the landing spot on the top of the hill is small, but as you can see in one of the pictures, there is a small grass feild at the base near the parking lot.
		In the spring, the west side of the hill is mowed and can be used for a landing spot, but other than that, and the top, its all weeds.

	Roller Coaster Science
		As the chain lifts the train, the kinetic energy of the motion of the chain is given to the train.
		At the bottom of the first hill (most coasters), the velocity (and kinetic energy) are the greatest, and the gravitational potential energy is spent.
		Ultimately, all of the gravitational and kinetic energies the train had at the top of the lift hill move into thermal energy by the end of the ride.

	CoasterQuest.com -- How a roller coaster is propelled!
		All you really have is a lift chain and a train of cars which usually has at least 96 wheels that hold it to the steel rails or wooden track.
		The drive system on most coasters is located directly underneath the bottom of the lift hill, although there are a growing number of new roller coasters being installed with the drive system at the top of the hill.
		It is also nice to have the drive at the top of the hill because it reduces the excessive noise at the ground level.

	OPERATING PRINCIPLE OF ROLLER COASTERS: CRAZY WORM
		There is a drop after the station that propels the train to the bottom of the lift hill.
		Once it reaches the lift hill the initial energy of the train's drop from the station has been used up so it must be pulled up the hill by a motor.
		Extreme hills on larger roller coasters might be able to throw the cars away from the tracks, so upstop wheels under the track are used instead of the pads so that the train is not slowed down.

	Block Brakes
		If your first section - typically the track's lift hill - takes a longer amount of time to complete than any other section, trains will tend not to be blocked unless there are too many trains for the track.
		In some cases you may want to divide the lift hill into two sections by including a transition track in the middle of the hill, creating a two-section hill.
		This is helpful if the lift hill section requires more than twice as much time to complete as any other section.

		At the beginning of the ride, the coaster car is pulled up the lift hill.
		When the coaster is released at the top of the hill, gravity pulls it down the track, converting potential energy to kinetic energy, or energy of motion.

		Potential energy is experienced while the roller coaster car is being projected to the top of the lift hill, where, at the top of the hill, potential energy will be at its greatest since this is point where the coaster is at its highest elevation.
		Gravity powers the coaster though the duration of the ride by detaching the car from the lift mechanism, which propels the car up the lift hill, and forces the coaster off of its highest elevation along the inclined track of the first hill and propels the coaster through the extent of the ride.
		From the top of the second hill, riders experience the same thrill of free-fall as on the first hill, but now the parabolic path of the coasters projectile motion must be taken into high consideration.

	Howstuffworks "How Roller Coasters Work"
		For most of the ride, a roller coaster is moved only by the forces of inertia and gravity.
		The only exertion of energy occurs at the very beginning of the ride, when the coaster train is pulled up the first hill (called the lift hill).
		The potential energy you build going up the hill can be released as kinetic energy -- the energy of motion that takes you down the hill.

		The transition into the lift hill is a bit abrupt as there are two sets of magnetic brakes.
		The lift provides beautiful views of the area and you catch your breath before diving down a nice drop (which looks like it will have a splashdown effect added at a later date) and into a zesty element to end the ride.
		I was afraid the lift was going to add a chopped up feel to the ride, and while yes, it's weird to have a lift in the middle of the ride, I think it does not take away from the ride in anyway.
