I spent a lot of years working at the family garage, and the one thing I was always paranoid about was a hydraulic lift failure. I always made sure the safety catch was out and checked the position of the car on the lift regularly, especially if I was hammering or trying to break a rusted bolt loose. We were also careful enough to not service full size trucks on the single ram lift, but some of the full size cars of the sixties and seventies were probably pushing the same weight. In all the years I worked there, we never really had a close call on the lift, and we never had the kind of epic fail seen here.
It’s hard to tell what happens in this video (especially without sound), but it looks like the lift cradle failed, which sent the truck to the ground, sideways. The mechanic in the video has undoubtedly found religion since this incident, but there’s no telling if he was held accountable for wrecking the customer’s truck. As a guy who’s made plenty of stupid mistakes turning wrenches, I hope not. Accidents happen, and that’s what insurance is for, anyway.
