I am trying to get feedback from owners of 4 post car lifts. I've searched the internet and all I find are ads and more ads. I live on a farm and don't have access to the big city and its resources.

So thought I would ask fellow home shop machinists if they have any experience that they could pass on to me. As I understand these lifts are activated by a large hydraulic cylinder that through a system of cables and pulleys lift the car,lock it in position,so it can be worked on. Intel Wifi Link 5100 Agn Hackintosh Laptops. Thankyou for your help. I don't own one, but have used a few and will eventually get a lift for myself.

I much prefer a two post lift. The platforms of the 4 post get in the way a lot. If you want to do wheel, brake, or suspension work, you still have to jack the vehicle up while it's on the lift. The two post lifts grab the frame so everything else is clear to work on. I've always thought that a two post with a drop in table would be handy for getting real heavy items up off the floor to work on or roll into a truck bed. I own a Fog 411 four post ramp that is in the barn. Yes it has a central hydraulic cylinder running the length of the ramp which pulls on four cables which go up each post and tension of which provides the lift.

Hydraulic power is provided by a 3 phase pump on one of the legs on mine. I imagine you can find a manual online somewhere for any older 4 post ramp and study it if you wish to know more. You need less concrete/stability in the base, and have less risk of the thing tipping over if something goes wrong. Its also 4 ton working load and as a result I can also pick up every vehicle I own on it apart from the backhoe (that is 8 ton), and use it as a straight reference to various points when setting up. While you do have to lift the vehicle clear of the ramp, if your pockets are deep you can get dual capability ramps that have a second small scissor lift permanently on the ramp and an integral part of it, then you can lift the vehicle clear of the ramp on a whim for the same accessibility as a 2 post. I dont have this but thats what the latest ones now sport. But I do have a jacking beam, which slides up the length of the ramp on rollers in a track designed for it and has a air jack.

Its easy to slide it under the vehicle and connect the air and pop the vehicle is lifted clear. I'm also happy to park a vehicle on it for storage, it has locking mechanisms in the legs which stop hydraulic pressure loss causing its descent over time. If you are doing lots of driveshaft and brake work, the ramp does get in the way a bit compared to a two post, but for the reasons above I went for a four post and am happy with that choice. I have a 4 post, made by bradbury which was a main brand in the UK 20 years ago. Audi A3 8l Sam Naprawiam Samochod Pdf. It has a master column with hydraulic pack and ram, the ram lifts one corner of the bed directly and the others via cables/pulleys.

There is a ratchet on the master column to stop decent if the hydraulics fail, likewise ratchet locks on each post to catch a cable failure. As for practicality a set of wheels free beams is almost a must and a jacking beam sure would be nice. I made a tray that slides between the bed to allow jacking, supporting things, and holding a drain tray for oil services. The bed is a handy place for tools when working, but as others say; for exhaust, engine/transmission jobs a two poster would be easier. But brakes, wheel alignment etc are easier on 4 post. Often opening the doors on a two post can be difficult if the vehicle is on backwards If you're tight for space then i'd go two poster, wish i had. I lift pickups all the time on my lift.

Just like any tool you must use it right, put the arms in the right spots where they won't slip, and read the lift manual to know balance points of different types of vehicles. Typical lifting trucks on my lift (A-symmetrical) is 2x4's you line up the pillars with the back side of the dash/mirrors, 4x4 trucks you line up the pillars with the center of the dash, extended cab 2x4's line up just a little further back than the back of the dash, 4x4 extended cabs line up with back of dash. Cars is the same deal, fwd 2 doors get lined up with the dash, rwd 2 doors are lined up around the same spot. 4 door fwd get moved a little bit forward as well as rwd 4 door cars. All of this along with pictures is in the lift manual. The thing to consider is you can't lift anything but a vehicle with a 4 post. Look at my link in my last post to see just a fraction of some other stuff I use my lift for.
