This Double Helix Coaster is equipped with two helix/spiral rails. One is a helix lift using a worm gear gearbox operated by hand crank or a motor to push many carts to the top continuously, another one is a helix slide rail for carts to coast down in a spiral. Both of them were built in the same tower just like the shape of DNA!
The helix lift is safer, more reliable, and compact. The whole thing was built on two base plates only.
