Bottle Jacks and changing tires

[Christopher Thwaites]

Using the Hilift in a receiver will work to a point but I wouldn't recommend trying to lift front or rear off the ground, too much weight.
If you could get it up high enough it would become increasingly unstable also.

Max limit for the Hi-lift X-treme is 4,660 Lbs.
The jack is TESTED to 7,000 Lbs but not rated for that, only tested. Most engineers provide a safety factor on the things they build just like a bridge. There is an overload factor built in most of the time.

Plus the X-treme Hi-lift is only rated to 4,660 Lbs for a height of 48".

The rating drops after that.

The upper 12" for the 60" model is only rated to 2,660 Lbs and has been tested to only 4,000 Lbs.

As Angel commented, the force to lift 4,660 Lbs is hefty at 177 Lbs at 34" on the handle; so some folks might have a problem. Obviously if you saw me you would know I can handle that, but like many jacks or hoists, the recoil of the handle can knock out teeth. I saw it happen once to a co worker and afterwards he didn't look like this he was hurtin

Our vans are heavy and you should know the weight of each tire point and axle (front and rear) fully loaded.

Would I push the limit? To get out of a jam, yes, probably to a point. The shear pin is designed to let go at 7000 Lbs but I would be very careful. I doubt I will ever try to lift the rear axle off the ground with a Hi-Lift jack. At least not on my 11K + rig. Just lifting one tire is freaky enough.

Also if you pick up a used Hi-Lift, be sure to verify the shear pin is still a shear pin and someone hasn't slapped a bolt in there and sold it.

[Greggd]

All of you using the Hi Lift Jack should periodically check your Shear Spring and Shaft assembly .
This can be purchased for about ($12.00) and easily carried in your Van . The Hi Lift is a valuable piece of equipment when maintained and used safely . And like Dave mentioned do not hover over the handle always stand to the side at a distance as far you possibly can from the handle . If you are a first time buyer you should consider the Extreme model as it will allow you to move Rock's , Log's , pull out wrinkled body work , or even use as a decent Come A Long .

That is absolutely correct. On my last trip where daveb and I did use the Hi-lift to lift a tire it was tough to push the handle. Without 2 persons, I think it would be nearly impossible for most people to push the handle enough to lift one end of the van up. But again, there are not any other options sometimes, depending on how you are stuck.

How did you get stuck again?

You had to ask.

Getting hung up on one of these:


Thanks daveb:


Hi-lift in action:


The winch alone would not have worked. No room for a bottle jack. Hi-lift to the rescue.

Steve, Greggde talked me into purchasing the hi-lift base. Really nice. It gives a larger footprint than the board you were using. Like 35 bucks.

I didn't know what a hi-lift was but after seeing your pictures I can see how that handle would be dangerous. Looks like it could do more than just knock out a tooth if it gets loose.
