MaxJax Fail Safe

[pac man]

Does anyone know if there is a fail safe built into this lift? For example, lets say I am lifting my truck to the top position and one of the hydraulic lines bursts? or a fitting explodes?

Normal lifts have ratcheting stops that are passed as the lift rises. Would a hydraulic blow out or leak on the MaxJax cause the affected column to have a complete failure and lower to the floor?

I realize the safety bars are a fail safe of sorts, but this isn't what I'm talking about.

Good question. Their web site does not seem to answer the question either. I'd call Dannmar directly and ask them.

According to the Features page there are self installed locking bars in the posts once it's up and "velocity-fuse safety valves" in the lift cylinders. If you lose hydraulic pressure they're supposed to close if the fluid shoots out of them above a certain flow rate.

As for what would happen to a vehicle on the lift if this happened? More than likely it would happen as the lift engaged the load so it might slip a few inches back to the floor or less, depending how fast it lifts.
