Trolley Jack Beams

[kambites]

It's no more wobbly than a jack under a single central jacking point (like jacking the rear of a car on the diff casing). As long as you don't try and use them on both ends at once it should be fine.

Looks useful, the downside would be once it's in place, clearing any under car ancillaries. You still have to have enough space to fit a jack under it.

cant think of many cars it would slide under , cant get a standard jack under alot of them

A pair of ramps is probably an easier solution unless you intend to work on the suspension.

think id spend the money on a extra jack rather than that

Are they any good? (this is mostly a laziness-based idea, but would also mean I could put the jack further under the car without the need to leave room for a trolley jack handle to swing up and down)

The review stating the screw shaft broke on first use would put me off that particular model. That should simply never happen.

Scissors jacks in general are very useful however. I have a couple of them to help with various jobs (e.g. raising my car enough to get my trolley jack underneath!).

I have made a beam for jacking up the rear of my Morgan. It is a light car so less load. There is SLIGHT deflection only as the angle adds to the stiffness.
Based on one that a Morgan owning engineer designed/made and been using for some time.
It is 30mm hardwood with steel angle along it for added strength.
Buffers on ends where it meets the chassis.
Centre marked for even lift.
ALWAYS use axle stands though and never leave it in place once the car is on stands.

How very Morgan!
