Accident-Free for 22-years

Michael Troy Richardson has investigated over 50 zipline accidents;  90% retained by Plaintiffs  because they find him first.   

A  
 t the 2020 ACCT Expo  an insurance  report  said that there were 6-7 zipline accidents per 100,000 over four years. 

Mr. Richardson's cases are about  50/50 Plaintiff/Defendant   Aerial Adventure Park matters  not directly related to zipline braking. 
​
He developed several  new   Zipline Auto-braking Trolleys   shortly   after   his caseload rose to five; and   received several new US patents designed to stop zipline  braking accidents. 
​

Safe Ziplining
 The Richardson Safety Trolley (RST) history began in 2001 when we—AA Machining & Welding, Inc.—designed and manufactured a 60-mph RST-02 for the 2002 giant zipline at Park City Mountain Resort (PCMR); the 3,500-foot-long zipline broke records with a 600-foot drop between platforms. Since then,  dozens of ski resort ziplines have utilized RSTs; our RSTs have an unblemished safety record.

In 2015, our company grew into Momentum Engineering and we designed our third-generation RST as a 3-lb. trolley for zipline tours. We're now selling the seventh generation  RST-23; it performed flawlessly again  and  in May of 2023 on a 20-degree slope  (see video)  
                                                        

​
The advantage of RSTs over free-wheeling trolleys (two wheels) is the RSTs' slope adjustment—via pin/slope settings—to equalize the slope for all zipliners and control their arrival speed.
The Petzl® two-wheel trolley is compared in this video to the RST. 

In 2019, our telescoping spring arrays solved the emergency brake problems.

Our springs   install in minutes. 



Zipline Accidents Doubling  Again

​
In 2016, he co-authored "Zipline Injuries on the Rise" with Rex Bush, Esq., published on hg.org and in Utah Trial Journal (2017). The article said that zipline injuries were increasing.

In 2023, 
Cameron Annas--CEO of Granite Insurance, said  there were    4.23 zipline accidents per 100,000 and predicted a 3.5 times increase over four years. (That is  nearly 15 zipline accidents per 100,000 (See Adventure Park Insider Magazine, Spring 2023 , pp. 42-45.))

MEET TROY

Many expert witnesses suffer from one of three issues: they’re either academics with limited practical experience, practitioners with limited academic experience, or professional expert witnesses with limited field and standards investment.

​Although, Mr. Richardson is working toward his Ph. D. in Risk and Safety Communications, he is well-rounded as a aerial adventure park builder and designer of zipline braking systems for
 22-years. He writes about each case and take the opportunity to strengthen the standards. Mr. Richardson is the CEO of Momentum Engineering, a DBA of ZipSafe, LLC. His company built the Park City Mountain Resort Zipline in 2002.

His seventh patent for zipline braking devices was filed in 2023.

I utilized Mr. Richardson’s services on a zipline death case and on a trampoline injury case. I was very happy with his services in both cases.
