The Zip Line

Riding a Zip LineWhat's a zip line? A zip line is a means of moving people or equipment over rough or pristine terrain using a cable and special zip line trolley system. There are many variations and uses. The most common use of the term is that of a ride. As an adventure ride, the zip line usually traverses over beautiful landscape or dense rainforest or desert canyons. The rider fastens into a harness or seat and launches out over the expanse. It is a thrilling ride, moving quickly and covering rugged terrain. Zip line rides slow to a landing speed as the line levels out naturally at the other end. Often there will be a platform or ground features that meet the rider just at the end. This occurs naturally because of the sag in the cable. The designer ensures the cable tension is not too tight and not too loose. Tight zip line cables will tend to keep the ride at a relatively constant speed, while a line with less tension will start fast and slow down near the end.

How big are they? Zip line rides can be short and low to the ground. This type of zip line usually does not fasten the rider into a harness...just hold on! The zip line handlebar is most commonly used in playgrounds or backyard zip lines and glides over a soft landing zone or swimming hole where the rider just drops off at the end. Long, high and fast zip lines are for thrill seekers and usually operated by professional adventure companies. A few zip lines around the world are known to reach speeds in excess of 100 miles per hour, and some are more than 1,000 feet above the ground.
