For travel on a cable, the zipline trolley includes a wheel, a brake, a frame, a hanger, and a lower slot. The wheel is disposed on a proximal end of a frame. The wheel includes a groove that receives a cable at a lower portion of the wheel and a wheel bearing. The brake is disposed on a distal end of the frame. The brake is connected to a given lever point and includes a groove along a brake bottom that receives the cable. The frame includes an array of lever points disposed between the brake and the wheel. The hanger is connected to a given lever point and suspends a weight. The weight applies a force about the wheel to the brake to control a rate of descent of the device along the cable. The lower slot receives the cable.

The invention relates to a roller coaster vehicle guided along a rail structure extending in a two- or three-dimensional plane and having at least one passenger seat (3), which is fastened to a chassis (2) guided on the rail structure, wherein the passenger seat (3) is fastened to the chassis (2) by way of an axis of rotation (16, 17) extending in a longitudinal direction of the vehicle, and the rotation of the passenger seat (3) can be influenced manually during the ride of the roller coaster vehicle. According to the invention, a rotation about the axis of rotation (16, 17) can be influenced by the force of an airflow along adjustable air guiding wings (18, 19) on the vehicle.
