One was in June , just months after the ride opened, when a bolt on the main hill came loose, causing the cart to go the incorrect speed, which then prevented the ride to be completed fully. The hill was redone after a brief closure.
In May , lightning hit the main hill, damaging it. The hill had to be repaired after a two-month closure, and it was then reopened in August. Occasionally, the ride might suffer a rollback, which is when the cart doesn't fully go over the main hill, and instead, goes back down the hill.
This is common, and it always happens on Intamin rollercoasters. The cart has been designed with magnetic brakes, so it can rollback safely, and be launched again. In August , Hurricane Irene hit New Jersey and caused unspecific damage on the main hill and the other rollercoasters around it. The theme park was closed before the hurricane approached. Given its speed, the ride will last approximately 28 seconds. Reaching speeds of mph in 3. With the fifth quickest launch acceleration time in the world, Kingda Ka can hit its top speed so quickly because of its hydraulic launch system.
This system can generate a massive 20, horsepower through interconnected accumulators, cylinders, motors, and pumps. However, the system does not generate this much force for every ride.
Fundamentally, the hydraulic launch system works in the following fashion. A piston subdivides the accumulators into a wet and a dry compartment, the former containing hydraulic fluid and the latter containing pressurized nitrogen gas. It is hard to know exactly when Kingda Ka's launch will occur. When the signal to launch is given, the train rolls back slightly to engage the catch car, then the brakes on the launch track retract.
Occasionally there will be a voice that says "arms down, head back, and hold on. Previously, Kingda Ka's horn sounded before every launch, but it has been turned off because of noise complaints from nearby residents.
The horn now only sounds when Kingda Ka first launches after being idle for a certain period of time. Kingda Ka's launch mechanism is capable of launching a train every 45 seconds, resulting in a capacity of guests per hour. Kingda Ka has a dual station - this is a station with two platforms. Each of the station's tracks accommodates two trains so that each of the four trains has its own station. Each train only loads and unloads at its station; it does not go to any others. The trains on one side are loaded during operation while the trains on the other side are launched.
This system works efficiently as long as all four trains are running and there are no significant delays in loading and checking the trains.
This system was not used at all in because only two trains were working that year. It also results in a very fast-moving line before the station, but a long wait inside the station, especially if waiting for the front row. An employee directs riders in line to go to a particular side of the station, but riders are then be allowed to choose the front or rear of the train.
Two operators load, check, and dispatch each train, and one launches the trains. The other is the remix version of "Eye of the Tiger" by Survivor. Both of these records can be heard during the queue and station.
Kingda Ka has four trains , painted green, dark blue, teal, and orange. Each train has five cars and seats 18 people. The first four cars seat four riders in two rows of two, while the last car has only one row of two riders. The rear row of each car is positioned higher than its front row for better visibility. Each of Kingda Ka's trains has a panel behind the last row of seats covering an extra row of seat mounts.
These panels could be removed for the installation of additional seats in the future. This modification would increase the capacity of each train from 18 to 20 guests and the hourly capacity of the coaster from to guests per hour. Kingda Ka's station is already set up for this modification; it has the entrance gates for the currently nonexistent row of seats. Kingda Ka's over-the-shoulder harness system consists of a thick, rigid lap bar and two thin, flexible over-the-shoulder restraints.
Because the over-the-shoulder portions of the restraint are not rigid, the hand grips are mounted to the lap bar. These restraints use a locking system rather than a ratchet which allows them to be pulled down to any position; when locked, they can move down to any position but not up. In contrast, a ratchet-based restraint only locks at each notch and will often be too loose or uncomfortably tight.
Kingda Ka's restraints are also held down by a belt in case the primary locking system fails. In order to speed up loading, riders are asked to secure their own restraints if they can.
On June 6, , less than a month after its grand opening, a bolt failure caused the liner inside the trough through which the launch cable travels to come loose and create friction against the cable.
The friction caused the train not to accelerate to the correct speed. Actively scan device characteristics for identification. Use precise geolocation data.
