Lashed this up to lift the bike engine out of the car, nothing else, so 65kg. what do you guys think just a bit rough or going to end in tears/a
and e?
Fine until the lifting arm swings off-centre and the whole lot folds.....
that can be easily locked good idea
honestly don't like the look of that one little bit.

before you push "the button, dial 999"
as it will all start to come down on your head!
and at least they will be on there way!
65kgs, is a few bags of suger, ive just lifted my 1600 xflow lump onto the bench. must be a lot more than that!
Steve
naah, i don't think its more than a cross flow, it's much lighter than a pinto, it's about 20kg less than me, i can lift and carry it myself, just not when strecthing over the car
Looks fine to me, maybee worth putting a couple of sky hooks on it. lol

i was going to say that, and thought, naaa, no one would get it !!
hahahahahahah
You wouldn't have asked unless you are doubting it. I think you have answered your own question.
Is the property yours? Will anyone else but you get hurt if it gives? Looks like a house of cards to me.

After a closer look it could be the screws into the end grain of that bit of 6x3 ish fixing the angle brackets that could be your weak link. Get a
couple of wall plate ties about 1000mm long each bend to 90 and fix those two bits of timber together a bit better, strap it up like.
main bolts are m10 holding the 6*3 to the roof, i'm not worried about the roof, the little angles up the top are intended to stop it trying to move sideways. the horizontal is braced to the wall, and the small angles there are just to hold it in position. the 2 pivots for the lifting beam are 8mm bolts right through. it'll be lifted in that position, not moved over the beam, the beam won't be swung anywere, i'm going to actualy lock the beam so it can't twist
I’m hearing you loud and clear now. “Only one way to find out Pritchard” the danger men!!!!!!!!!
If you can swing on the end of it and jump up and down with minimal movement it might be ok, but I have to say it doesn't look terribly strong. What size is that roof joist it's all tied into? Looks rather slim for the length for putting any major load in the middle, but might just be the photo exaggerating things.
I wouldn't be too worried about the roof beam - they have to withstand the weight of a whole heap of snow or a couple of people on the roof for repairs. Joists are specced for a maximum deflection under load, but overloading them (within reason) just makes them deflect further, there is a *LOT* of spare capacity in most joists..
Nope imho
If you happen to get a 'swing on' when lifting it could quite possibly all end in tears 
airfix engine ok
Try it. but you'll want one of these.
Seriously though it's a bike engine, just lift it, no need for a hoist IMO. can shift a pinto as far as you like with 2 blokes.
Design is all wrong.
You have bolted through the joist so you have not used the full thickness of the beam it could split where the bolts go through.
Also these bolt go through the down piece with the grain so this could also split along its grain and drop.
I would have used joist hangers between the two roof joist's and put a beam across then bolted the lift onto this.
Btw joist hangers should go up and over the joist, then nail or bolted into the joist on the opposite side of the beam to use the full thickness of
the beam.
Just my opinion.

But we are talking about a bike engine! The hoist and beam probably weigh more than the engine. I'd be happy swinging 65kg off what you have. Just keep an eye on it!!
i think you could only lift about 50 kg before the timber its attached to gives way .. as its only got 4 screws lol

Gone to a lot of time and trouble and expense for what should be a basic lifting job- what is wrong with getting a mate round and strapping engine/
cradle etc to the plank as close as posible then just liftingit up and out we changed lots of engines like that when I was a lad- Vauxhall, Viva,
Hillman Hunter. Reliant Robin....
Come to think of it I do get a few twinges in my back now and again
Good luck.
Mike
That looks destined to fail in any number of ways, can't you build a couple of pillars either side or knock a couple of bricks out and put an RSJ across ?
Or try this
If you doubt it's strength, just hang off it first. If it doesn't wobble too much and holds, carry on. If not, it's a bike engine: just pick it up you girl. I did my blackbird engine swap on my own, and that's quite big for a bike engine.

Well it worked and i'm still here!
i put the hook right down at floor level, and stood in the loop, then lifted it a couple of inches and tried jumping at that was all good too. i did
lock it so it stayed inline with the horizontal support, and moved the car out from under the engine, and it will be replaced with a better solution
when time allows. i did lift it into the car myself, 3 or so years ago, but maybe because of doing that sort of thing my backs not too clever
I once put my back out badly getting a bike engine out of a boot. Its one thing lifting it when you can get close, and quite another leaning over to reach it. I ended up with it balanced on the boot opening and unable to move it either way!

RickRick,
If you post/pm some more details I could help you size up a proper steel beam for future lifts

Good to hear it turned out ok.
But constructing your beam to the weight you'll lift is the wrong way around. Always spec your beam to the capacity of the lift/hoist.
You'll be surprised how fast things can turn ugly when for instance you forgot to take a bolt out. Hell even a proper earth strap would have
resulted in the hoist coming down instead of the engine going up. If you make sure the pulling force of the hoist is the weakest link in your setup,
then you'll be safe. Unless ofcourse you go to extreme abuse....
Because you know then once you install a hoist like that... you'll start using it for all sorts of things... and every time you'll load a
bit more, because... it's only 2kg more right..... Either install it properly, or expect it to come down one day.
