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.

The top of this zipline is seen near the top of the mound. Notice where the trees (near the middle) are cleared.
