Attraction "Catapult" (second name - "Slingshot") can be used as circus equipment or sports equipment. The construction of a small height (15-20 m) is most often installed on the beach or in the park area and is a prototype of a swing. Two racks with a crossbeam and elastic ropes are mounted in the ground. The passenger is attached to the cables with the help of seat belts and reliable rigging. The function of the starting mechanism is performed by the service operator, the winch lifts and descends the passenger. To extend the entertainment time, a trampoline is installed under the crossbar. Then the skater himself can push off and make jumps, somersaults in the air.
Also known is another attraction "Catapult", which is installed on a swimming base. Its second name is “Surface Swing”. This is a structure of two side racks and crossbars. Four elastic pendants with a seat below are connected to them. The device is mounted so that the crossbeams, the seat and the ropes form a parallelogram mechanism in the rocking plane. It provides a plane-parallel movement of the chair. The front seat of the ride is fully open, and the inside has a smooth surface. On such a swing, the rider sways measuredly in the air. The purpose of this attraction is to throw a passenger into the water. It is achieved thanks to an electric drive platoon suspensions. Together with it, the throw function is carried out by the latches of the cocked position of the chair and the vertical position of the suspensions, the trigger mechanism, the drive of the stroke and the adjustable stops of restriction of the stroke.
Another attraction "Catapult" is gaining popularity now. It is installed on the water and is intended for a large number of people. His second name is Blob. This is an oblong shaped inflatable pillow . She is not fully inflated. A man sits at one end of the lowered section (closer to the water), and a man from a low tower jumps to the other end of the blob. Due to the redirected air pressure to the other end of the device, a person is “thrown out” into the water. The force of pushing depends on the height of the jump and bloat blob.
Attraction "Catapult" - entertainment for these extreme sports. Those who want to tickle their nerves and take off on the cannonball can use this modern device in public places. This device for producing a burst of adrenaline was invented by Troy Griffin only a few years ago - in 1995.
Attraction "Catapult" in St. Petersburg consists of two high towers that are firmly mounted on the platform. Two elastic ropes are attached to them. At the other end of the cables, a double (or single) chair is fixed, protected by a spherical steel frame. Before the start of the rope is pulled and the "capsule" with people with the help of an electromagnet is held on the platform. When it is turned off, the chair abruptly catapults upward. Passengers at this moment experience a strong overload, similar to space. For 4 seconds of flight to a height of 70–80 meters, the speed of the “capsule” reaches 19 m / s. This is the speed of a locomotive flying from a high mountain. During the flight, the seat with passengers rotates around its axis. This rotation allows you to get additional sensations and makes the attraction more interesting. After several swings up and down, the tension of the cables is reduced and the chair is lowered to the platform. At this time, from a height you can see other attractions in St. Petersburg.
