In this article, machinery experts at Robson Forensic provide an introduction to hydraulic systems and the hazards they present. Hydraulic systems are used everywhere, from forklifts to landing gear to industrial systems and the largest earth-moving machinery. Some of the most complex and critical life safety hydraulic systems are found on board ships and aircraft. Expertise in those environments translates well to industrial applications on terra firma. Required to be powerful and reliable, hydraulic systems are not, however, immune to malfunction and failure.
In this article, Mechanical Engineer, Brian Kelly, P.E. discusses the incidence of injuries involving overhead doors. His discussion includes an overview of overhead door anatomy, an explanation of the hazards, and a description of safety precautions to protect users from injury.
Failures that allow the stored energy within the spring of an overhead door to be rapidly released can cause devastating injuries, often to unsuspecting or untrained personnel. Failure of the overhead door balancing system can cause the door to rapidly close under its own weight. The experts at Robson Forensic are experienced in investigating and testifying in overhead door cases and a broad range of other matters involving facilities safety.
