Getting ready to yank the old engine and transmission out of my C3 Vette. I have the Northern Tool 2Ton lift and leveler like below.

I am planing on removing the left front tire and positioning the hoist on the side. Kinda like this, except from the drivers side.

adding a swivel hook makes a crane far more user friendly

My question is if I have to extend the hoist boom to the 1/2 ton position for the right reach, is it safe to list the engine and trans together? Based on the engine weight of ~550 lb's and the M21 transmission at ~100lb, I would be lifting 650lb's. Thoughts?

Ive got several engine cranes (3) in my shop, and my larger engine crane was used to move my 2500 lb mill,
Image

around the shop to its current location, its rated at 2 tons and it easily lifter the 2500lb mill, but I needed to weld on 4 extra swivel wheels before it could easily roll with 2500lbs swinging on the crane, in the shop so I'm sure the design and capacity of your engine crane will have a huge effect on what you can do with it.
my smallest engine crane is rated at one ton, and while it will work with an engine and transmission, ... its seldom used, because its just not that steady as the leg base measurement foot print,is significantly smaller than the big engine crane, and I can,t roll an engine stand between the legs to accept the engine once Ive pulled one.

Maybe I’m over thinking it but when it says ½ ton (1000lb’s) on the hoist and I’m lifting roughly 650lb’s, is there a safety factor I need to worry about? I’m thinking I’m good but I don’t want this to happen.

again it depends on the quality of the equipment, most have some safety factor already built in ,if it says 1000lbs its generally going to not fail at something barely over the rated load like for example,1050 lbs , but most import crane hydraulic assembly's are not known for utter dependability either.
if your really concerned you could weld a couple sections of 2" square steel tube with 3/16" thick walls to both the crane support and boom making them far harder to bend than the original crane design, your local steel supply will be only two happy to cut you two sections at a fair price and any decent welder could weld that

you might even install a larger hydraulic cylinder (having a welder is so darn helpful,
OR you could sell the current engine crane and upgrade to a higher rated version

I think youll be fine lifting both the engine and trans, but I would not be sitting under the load either, obviously think about what your doing and what might happen if the hydraulics fail and stay out of the way, of any potentially dangerous areas,as much as you can.

It stared as a Matco 1200 lb capacity stand and I modified the legs so that the stand takes up less floor space and can store more compactly. I also added brackets to store the legs. Oh and I also had the stand powder coated and then pin striped it too.
Grumpy is right too, it's worth it to buy a high quality stand and not chance the kind of problem he described. My leg modification is plenty strong with Tig welded steel inserts and grade 8 bolts.
Image

The legs come off and store vertically along the mast. you can see I protected the holding brackets with corrugated sheathing. I also added a pair of rubber casters so that when the legs are off, 4 casters support the stand. They are mounted 1/4 inch off the ground when the legs are on so that they do not touch.


that engine stand paint job looks sharp!
ALL NICE FEATURES

brad_bb MODIFIED HIS ENGINE STAND FOR DETACHABLE LEGS
Image
I can see where the detachable legs might come in handy in a smaller floor space shop, and that particular stand design seems to be exceptionally stable

Im sure if you have a few buck$ you can spare the addition of the larger caster will further enhance the stands versatility, I found the addition to all my engine stands well worth the price, making the stands far easier to move when loaded with a big block engine!
probably a better design but not foldable
[color=#BF0000] I like what you did, that looks nice,btw,
Ive got two types of engine stands designs in my shop,(4 engine stands)but I added 4 of these wheels to each stand

Like others, I had old engine stands I never used because I aquired better ones. I put one to use on my whadayacallit I made out of an old roll bar to hold big/heavy things I want to work on, paint, etc. while being able to spin them around to work on different sides.

Not A T/A has the right idea Grumpy.
Engine stands are handy for Diff& Trans builds & more .

I was looking at the engine crane converted to a car trailer pictures you put up.
Idea is Novel but risky. No suspension or leaf springs or Trailerbrakes.
Never get it Titled & trailer licensed in Illinois.
One good bump & its bouncing all over & tow vehicle.

Handiest thing to have is a 18 foot Dual Axle Car Trailer & A Large 4X4 Tow vehicle.
Strap near anything to it. Go anywhere.
