Below is a rare video of a tow vehicle going down the ramp and sinking. I know these events happen from time to time but how they happen never seems to be well explained. Maybe this group can better explain but my thoughts below.
This example has a couple clear factors:
This example has a couple clear factors:
- The ramp was slick, due to low tide
- The jeep was likely over it's towing capacity.
- Is it just me or does the trailer appear to be floating? From 43-59 seconds in the video the back of the trailer appears to float to the left several feet. If the transom tie down straps were in use that would make sense but watching the video it seems clear straps were not in use. I can't explain the floating but if the trailer was floating, it could have lifted the rear of the jeep reducing traction. Maybe the M shaped hull somehow got caught on those bunks.
- Some of the you tube comments reference a failed clutch (or other drivetrain component) which is possible. Unfortunately the video isn't clear enough to tell if the wheels are spinning backwards, forwards or locked at that point but I suppose it's possible the driver was slow to hit the break once the car started going backwards.
- The driver leaves the vehicle and the car rolls again. It's clear the front wheel spins which I think is clear evidence that only the front wheels were holding the jeep at that point and letting off the break resulted in the final failure. It's also possible that the driver's weight was keeping the back wheels on the ground but once he exited they floated and since they were the only locked wheels, the jeep rolled.
