    • A trolley braking system for smoothly reducing the speed of a rider supported by a harness on a cable or rope approaching a landing platform comprises a vessel containing a fluid of selected viscosity and having a turbine rotatably mounted on a shaft in the interior. A braking cable is secured to a reel on the turbine shaft outside the cylinder and routed through a pulley to a braking block, which is slidably mounted on the cable between the trolley and the landing platform. The system may also may also include turbine blades of adjustable dimensions, so that the braking force may be controlled. The system may also include a counterweight suspended by a retraction cable which is coupled to the turbine shaft to rewind the braking cable on the reel for repeated use.
    • 用于平滑地降低由靠近着陆平台的电缆或绳索上的线束支撑的骑手的速度的手推车制动系统包括容纳选定粘度的流体并具有可旋转地安装在内部的轴上的涡轮的容器。 制动电缆固定在汽缸外面的涡轮轴上的卷轴上,并通过滑轮被引导到制动块,制动块可滑动地安装在手推车和着陆平台之间的电缆上。 该系统还可以包括可调节尺寸的涡轮机叶片,使得可以控制制动力。 该系统还可以包括由缩回电缆悬挂的配重,其联接到涡轮轴,以将制动电缆重绕在卷轴上用于重复使用。
