Knott Laboratory provides forensic engineering and animation, Civil & Structural, and Fire & Explosion Investigation services to reconstruct accidents.
Trailer Jack Accidents
Trailer jack investigations often focus on the condition of the snap ring and whether or not it had been properly installed.
Trailer jacks are designed to withstand extreme vertical loading but are often subjected to unforeseen lateral loading conditions as the user attempts to maneuver the trailer onto or off of a trailer hitch. In many popular trailer jack designs, these lateral forces act on a single snap ring, or retaining ring, which holds the jack in place on the trailer. Failure of this snap ring could allow the tongue of a loaded trailer to fall to the ground, potentially injuring an unsuspecting user.
In cases in which a trailer jack becomes separated from the trailer, the investigation often focuses on the condition of the snap ring and whether or not it had been properly installed. Force analysis and exemplar testing can further determine the lateral loading conditions necessary to separate the trailer jack from the trailer.

I want to express our continued admiration for the quality of Knott Lab’s work both in accident reconstruction & in the preparation of demonstrative evidence. On the basis of your deposition testimony & the animation of the accident, the defense admitted the negligence of their employee, that it was the direct cause of the plaintiff’s injuries.D.W., Attorney, California

[Richard,].. Your assistance in the case has been invaluable. I am very pleased that you were able to rebut the findings of the two State Police officers and the defendants expert. No one else was sharp enough to focus on the oil spill in the photos and it was gone when the State Trooper did his final report.T.B., Attorney, Massachusetts

I wanted to personally thank you for all of your hard work and dedication in helping to get the case successfully resolved. If not for your hard work, your expert opinions and your keen analysis on this case, we would never have been able to settle it for the amount and/or in the time frame in which we did. It was truly a team victory.T.W., Attorney, Illinois

The work you did on the case was outstanding. Prior to going to the mediation, we sent your animation of what occurred to the defendants. I truly believe that your animation allowed the defense to see exactly what happened which, in turn, allowed them to appreciate their liability. Regardless, I think your work was outstanding and want to thank you.S.G., Attorney, Missouri
