2002 Park City Mountain Resort Zipline
22-years ago, our company built a zipline for Park City Mountain Resort (PCMR) set to debut at the 2002 Winter Olympics. PCMR contracted Mr. Richardson's company (AA Machining & Welding, Inc. (Utah Government Steel Contractor) to develop a safer zipline braking system for the resort; see his patented passive braking technology.

Lake George, New York
Steep Ziplines need autobraking (friction based) trolleys and a properly designed spring array. This New York Zipline's (in the photos) has a 30-degree slope. Stopping zipliners proved dangerous with their magnetic braking trolleys.

30-degree Slope at Lake George, New York
The top of this zipline is seen near the top of the mound. Notice where the trees (near the middle) are cleared.

Dual Braking Zipline Spring Arrays
Tested in 2021 at American Adventure Park Systems in Georgia (see full video).

Testing Dual Zipline Spring System w/ Sandbags
All spring arrays need to be tested; always document testing and training.

Utah Ski Resorts
Most Utah Ski Resorts utilize spring arrays and auto braking zipline trolleys from the original trolley design at Park City Mountain Resort.
