摘要： For stopping a zip line trolley, a zip line braking system includes an impact device, a non-zip liner parallel cable, a freewheeling pulley, a tether, and at least one spring. The impact device rides on a zip line cable, wherein the impact device is positioned down the zip line cable from a zip line trolley that rides on the zip line cable. The impact device does not ride on the non-zip liner parallel cable. The tether connects the impact device to a first freewheeling pulley. The impact device applies a force to the first freewheeling pulley via the tether in response to a zip line trolley contacting the freewheeling pulley. The at least one spring is disposed on the non-zip liner parallel cable and slows the freewheeling pulley, wherein the freewheeling pulley decelerates the impact device and the zip line trolley via the tether to a stop.
