    I believe there is an article in Machinist Workshop on this topic. It was a couple of years ago. I'll try and check my back issues later tonight.

    Years ago I had a hoist that I modified for outdoor/rough terrain usage.

    I replaced the tiny wheels with 12" diameter by 4" wide, filled pneumatic tires. On the back side, I welded on three point hitch attachment points for one of my tractors. In use, you'd back up to whatever you needed to lift, hook up, lift, balance and drive off with it. The best thing about the arrangement is that the weight of the tractor and the three point hitch stabilized the lift - I never once lost a load to tipping, etc.

    The addition of the tractor makes use inside a garage or shop problematic due to clearance issues, but it's great for picking stuff off a trailer and getting it through a doorway and at least onto the shop floor.

    Sorry, I don't have any pics, but you get the idea.

    No not you, this fellow showed pictures of the before and after shots of the base, that he ground out and rewelded. If I find them I will put them up.

    Leg-opener

    Candy
    Is dandy
    But liquor
    Is quicker.

    So?

    The best "leg opener" is booze aka liquor.

    The problem I've run into with engine hoists for machinery is that the legs are too close together to allow the machine (think Bridgeport) to be lowered directly to the floor. My mod would be to increase the distance between the legs somehow.

    You bring up an important issue.

    I have seen many engine cranes over the years...and some are so poorly built that they do not deserve being called an engine crane.

    Any suggestions as to how to improve the poorly constructed ones?

    You guys talk about larger casters. I took the easy way out. I had a $12,000 concrete driveway put in and I can run from the shop out the door, across the barn, up the drive to the front door sidewalk with no interruptions in the concrete!! Means I can push my tool box to the back of the kitchen door if I'm on an long and involved project. Best tool I ever got for myself was this flawless concrete driveway and barn floor. (I understand it's a long way around to solve the problem )


    Tiffie, If I don't get a PM about any garage sales you got planned I'm going to be PO'd !! I expect at some point you'll be selling off to make room for more! Or, if you have found a way of taking it all with you let me know, I'd like to take mine too.

    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...

    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.

    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?

    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.......

    Lower profile casters. Wider base.
