Choosing the right trolley for your zip line
A zipline is an outdoor recreation sport/adventure sport where a freely moving pulley is used to ride from the top to the bottom of an inclined cable. It is emerging as one of the most popular outdoor activities.
How did zip lining begin?
The theory of zip lining that today is fundamentally an adventure thrill ride, was invented out of necessity. The gravity-fueled transfer using cables and pulleys threaded between two points was developed by workers and residents who were required to instantly transport people and supplies across canyons, rivers, and other impassable areas in remote regions around the world.
Which Zipline trolley is right for you?
The Head Rush LightSpeed Zip Line Trolleys are engineered from the ground up to have superior performance on zip lines, specifically lines with impact braking. Starting from the compact and affordable Micro Trolley to the entirely rebuildable and customizable Impact Trolley, there is a Head Rush LightSpeed Trolley for all the zipline requirements.
- Micro Trolley: An affordable zip line trolley and the smallest in size, the Micro Trolley explains many of the common concerns seen during zip line braking. Its long-lasting impact surface, high retention backup connection slot and forward of centre connection point all lead to smoother, more efficient braking and longer life for the trolley and brake system.
- EZ Clip Trolley: Nothing like the LightSpeed EZ Clip Trolley is available in the market. The zip explicit design supports long life and smooth impression braking with perfect size, weight, accessory options and price. It is the most durable, easiest to connect zip line rider trolley.
- Impact Trolley: The LightSpeed Impact Trolley was the original Head Rush zip line trolley and the first rider trolley to tackle issues connected with impact braking. This trolley is built for long, high speed and large diameter zip lines.
Why do zip line trolley bearings matter?
Bearings are one small component of the new head rush zip line trolleys. The bearings extend the trolley's lifespan, support the higher speeds on the line, and deliver it a smooth ride down the line.
Most noteworthy, in other trolleys, the bearings are the prime things to fail and are often the reason zip line trolleys have to be retired. Head Rush engineers delivered the new zip line trolleys with high-quality bearings that will last longer.
What is a Bearing?
A bearing is a mechanical component that provides movement and decreases the friction between two parts. Bearings support the movement and reduce friction for less wear on the parts over time, instead of two smooth surfaces sliding past each other, which would cause lots of friction.
Why are zipline trolley bearings important?
In zip line trolleys, bearings are employed inside the sheaves to let the trolley roll smoothly. Zipline trolleys can attain high speeds while travelling down a zip line, and that speed can cause a lot of friction and heat inside the sheaves.
Head Rush desired to produce a robust trolley with a longer lifespan, so the EZ Clip and Micro Zip Line Trolleys emphasise precision bearings. The head rush doubled down and put two inside each sheave. This distributes the load of the rider over 4 separate bearings so they don't have to work as hard and so each bearing lasts longer.
Different parts of a Bearing
The bearing has an inner race and an outer race, and these races will have grooves for the balls to roll along. The bearings inside the head rush trolleys have 7 balls each. The balls are held between the races by a cage that maintains symmetrical spacing of the balls while allowing them to rotate freely. The ultimate component is a shield that guards the internal pieces against contamination while helping hold in the lubricant that surrounds the balls.
ABEC rating
High-quality bearings may adhere to certain standards that allow them to earn an ABEC rating. The ABEC rating is a measure of the uniformity of the shape and surface of the bearing components. Bearings can be rated ABEC 1, 3, 5, 7, or 9, and the higher ratings represent lower tolerance for variation.
What does it mean for a bearing to be shielded?
A cover sits over the balls and cage of the bearings between the two races. A snug fit is beneficial because it keeps out particulates and water, but creates friction where the rubber seal touches the rotating inner race.
The bearings inside the head rush's EZ Clip and Micro Trolleys feature metal shields that sit between the two races. There is a gap between the shield and the rotating inner race that eliminates a friction point, hence reducing the heat buildup and wear.
Why Head rush trolleys are better than other brands
The Head rush trolleys are lightspeed and are designed for zip lines and engineered for durability. Head Rush has a variety of zipline trolleys to offer. One can choose from the fully-featured customizable impact trolley, the lightning-fast one-handed install of the EZ Clip or the compact affordable micro trolley. Each head rush trolley is well-equipped with premium high-speed bearings and optimized for stable and uniform impact braking.
