Was out on the ATV this weekend with my Bro-in-law when I had a nasty rollover on a hillclimb. It was near vertical at the top and although I have made it up on my quad plenty of times, no such luck on my borrowed ride. I tried and tried to avoid all the things that make a quad roll over; I got off the gas, I avoided the back brake, I let it roll backwards. But no no avail. It flipped over, I said some choice words, peed a little, then smacked my backside hard enough to notice for the next week or two.

The quad will be getting some repairs, I am OK, but I am wondering about what I could have done to stop this?

Bruised in the 'Burg.

Lean waaaaay forward? Know your machine. Don't borrow a ride an hit the heavy duty trails.

Was it 2x4 or 4x4?

Try a 2 wheeler next time If it does roll over on you at least it has only half the weight to crush you with

Most likely cause of the problem in the first place: insufficient speed. Big Mo (momentum) is your friend. It's way better to be going a little too fast at the top rather than a little too slow.

Was this a sideways or backwards rollover?

Common to both: keep your weight as far uphill as possible. If the quad is pointing uphill, get your ass off the seat and practically lay on the bars. If it's sideways, get your ass off the seat and lean as far uphill as possible.

Sideways: Turn the front wheels downhill so the the quad will follow the front wheels.

Backwards: let it roll backwards, turn the front wheels either way to try to get the quad sideways and then quickly turn the front wheels to point the quad's nose downhill.

If you get to the point where it can't be saved, BAIL! It's best if you jump uphill. If you can't go uphill, then go to either side but NOT downhill! The last thing you want is that heavy lump chasing you downhill.

Hello to all

A roll-over transfer for foundry equipment is disclosed in which a "C" shaped frame rolls along a base combining translation and rotation between two end positions. The frame is powered by piston and cylinder actuator connected for a cycloidal operation to provide maximum acceleration and deceleration at the ends of the frame travel. Cables are connected between the frame and base to maintain a predetermined relationship between the translating movement and the rotating movement. Primary and supplemental stops cooperate to positively prevent over-travel in the event of a failure in the drive system. A single clamp and draw actuator is centrally mounted on the frame for clamping and drawing foundry equipment. The machine is flexible in use in that it can be loaded and unloaded from any one of three directions in each of its operated positions.

Thanks for sharing

I've rolled over a canoe once or twice, as well. It's no fun. Well, it's no fun sober.

Is this guy just telling us about his canoe and not trying to sell it?
