The spinning drop tower ride also was called spinning shuttle, it is commonly known as the jumping machine. The main body is a tower structure. The cockpit can instantly rise and fall along the tower body track and rotate 360 degrees during the lifting process. People sitting in it not only feel the excitement and scream of free fall and breaking the earth's gravity, but also feel the pleasure of flying dizziness.
①Classified by equipment height
Drop tower are mainly divided according to the total height of the equipment. Common heights are 9 meters, 11 meters, 20 meters, 24 meters, 28 meters, 35 meters, 44 meters, 50 meters, 68 meters, 74 meters, etc.
②Classified by the number of people carrying
The size of the equipment is different, and the number of people（quantity of seats） that can be carried is also different. The common carrying number of the drop tower is 6, 8, 12, 16, 20, 24, and 30.
③Classified by driving power system used
There are two driving systems for the lifting tower, one is a pneumatic system and the other is a hydraulic system.
The manufacturing costs of the two systems are very different. Each has its own advantages. The pneumatic system is expensive, uses a large amount of air, and has a high pressure value. There are many air storage tanks and large air compressors. The equipment occupies a relatively large area. The pneumatic system is easier to maintain and the maintenance cost is lower. The drop tower using the pneumatic system is faster, and the ride experience is more exciting and fun. The hydraulic system has low cost and small footprint, but the hydraulic system is more complicated, more troublesome to maintain, and more prone to failure. The ride using hydraulic system experience is not so exciting and interesting.
