    If it's new I wouldn't be to worried about lifting with it.
    Mine being a folding model has 6 wheels, 3 sets of 2. I have had the steel flexing so much when I was lifting the mill that the back 2 sets were off the ground. When I started to lift it, it took a few pumps after the sling was tight to lift the mill off the ground while all the steel flexed and bent.

    Over here they most places don't sell the 2 ton model anymore. They have derated them but claim they will still lift 2 ton. Must be something in the legalities of it.
    Where I bought mine it was the last and I had a choice of either the 2 ton manual pump or the 1 ton air pump model for the same price. I bought the 2 ton because the steel was thinner on the 1 ton and I can always change the pump over latter.
    One thing about these ceap cranes compaired to the one you linked, is the weight, try lifting one of those into a trailer on your own.

      Why do you think we have two?............LOL

      I can show you a pic of a buddy that lifted an engine and I don't think at the time was fully aware of what the ram was doing........yikes!!!!!!

        This one is a good design. Full details can be found here

              I have what may be an obvious question but if you're using an air/hyd ram and the air line blows or if the air cylindar suffers a catastrophic failure, will the load just drop or do the hydrolics take over. I guess what I'm asking is if anyone knows what the failure risks are when swapping to the air operated ram.
              I'm in it for the parking....

                The air/hydraulic rams work like this: there is an air motor that does your hand pumping for you. If something craps out in the air things simply stop moving.

                The 8 ton long throw air/hyd rams work great on engine hoists.

                  Hi Jim,
                  I wrote this up for another membber a while back.

                  You will need somewhere to host you photos. I use Glacern as they are advertising on here. The instructions are on there as well. Just make sure the photo's are 700 wide or less, you will need to resize them before up loading to Glacern.
                  http://www.glacern.net/
                  You can also use photo bucket.

                  After you have uploaded your photos on Glacern keep the link in a folder for latter use.
                  When you click on the (Post Reply) you are taken to the (Reply to thread) screen. On the second row down from the top of the message box you will see a square yellow and black icon which looks to be a picture of mountains. Click on this, another small window will pop up, then insert your address you got from Glacern and push OK and it's done.

                  Hope that helps.
                  Dave

                      The nice thing about the OTC one is it doesn't derate much......2200 retracted 1650 fully extended, I have a ShurLift engine hoist made in Manitoba and it's probably about 1/3 heavier on a scale than the Chicom to OTC comparison, mine still has a lil slop that could be tightened up but doesn't foldown so storage could be an issue for some.........anyway heres the pix.......grin.......there was another one floating around the net that had folded w a BBC hanging on the hook, can't recall if it slammed into the floor though.......

                      Anyway even with parts stripped off this engine would be waaaaaaay over probably the hoists retracted rating.......I wouldn't want to be the one opening the valve to lower.......LOL I think he may have grabbed it from this position w a loader and then realized the ram wouldn't retract.......

                        So with your present engine crane, could you pick up a Bridgeport, a 12" engine lathe or a 20" vertical bandsaw?

                        Each machine presents a different challenge to the engine crane...

                        The Bridgeport in terms of weight and base width.

                        The 12" lathe for weight and lateral stability.

                        The 20" vertical bandsaw for its extreme height and base width.

                        So what improvements have others made to meet these challenges?

                          Hardtail, looking at your photo of the Cat engine. I think if it was my engine I'd be hurrying to get a bucket full of loose sod under it before the hoist collapsed! Good thing the head is off.
                          I've seen loads just like that on engine hoists...right down to the bend in the hydraulic cylinder rod like in your photo.
                          I usually just tell them to not crawl under it, pray, and walk away.

                          By the way I remember seeing the one of the BBC folding a new engine hoist and I managed to find it.

                          Apparently the transmission was hooked up as well, but considering the weight of a stripped down BBC and transmission, it would be a stretch to say he had anymore than 1100 lbs on it...and he had the hoist in the 1 1/2 ton position.
                          Good topic TMT, I think we all have had to move iron with the help of an engine hoist, some good info here.

                            Thanks...I thought it would prove interesting.

                            I figured this year if I have any spare time I am going to remake several of my engine hoists so they are customized for machine moving...and I always like to discuss the subject before cutting and welding.

                              Is that what I have to do to get my main arm to fold down properly.
                              I have noticed some engine cranes have a thinner wall thickness than mine, thats why I bought this one.

                                I have the Horrible Fright version, it didn't have any problems lifting my SB 10L off a trailer 3 weeks ago....

                                Hadn't even thought of modifying it...
