Heavy Duty Scissor Jacks

[btcsxj]

Has anyone used a heavy duty scissor jack, like the one below as an alternative to a hi-lift or the OEM jack once you move to larger tires.

I understand that these are typically used to level 5th wheel trailers, and a plate will have to be made for the top to correctly cradle the frame or a rock slider... They have a 7,500lb capacity and lift 24"! AND these are so much more compact than a hi-lift or bottle jack, won't leak like a hydraulic bottle jack and they're nearly as stable/reliable as a jack stand since that ACME screw isn't going to start spinning on it's own.

I deal with very large trailers in the industry I work in. We do have scissor jacks on the trailers, but by no means to we uses them to level the trailer. They are only used to stabilize the trailer from rocking. I've seen guys try to crank these things to level trailers before, and they usually turn into a jack taco. I've had a scissor jack fail on me before when using it to jack up a vehicle and I would never trust them again. Sure it's rated for a high weight rating. But that is a perfectly vertical weight. Any movement in the jack especially on uneven terrain, these things have a tendency to fold in half.

Interesting considering most OEM automotive jacks are of the scissor jack variety... Someone should make one for this application...

Hi-lift jacks are F'ing dangerous for one thing.
I just carry a decent bottle jack to fit under the axle.
There's no Hi-lift big enough to use on my truck anyway.
