Hi,
Does anyone happen to have an SGS engine crane?
If so would you be really really kind and measure the internal dimensions of the jib extension, where the hook chain attached?
I am looking to purchase a crane to handle a roof tent. SGS offer options that are low enough to fit under my car but I need to know the jib dimensions to fit a roof tent lifting arm.
I have asked SGS but no response yet.
Thanks!!
I had a Howling Moon RTT on my Defender, I used an overhead gantry crane at work but I've seen people with a rope pulley system rigged to the ceiling of a garage to remove a RTT.
I can't imagine how an engine crane will work, they don't lift very high and if you extend as you mention it might then topple forward under load. RTT generally don't weigh more than ~50kg - can you not enlist some friends and lift it off?
I've got a Clarke one, no idea if it's the same though.
I agree with rusty, at full extension it can't hold much weight, (unless it's a very low car) if you extend it to go high enough, you'll need to extend the legs to stop it toppling forward, and it's unlikely to take more weight than you can lift.
IMO you need a strong garage roof, an A frame over the car, or some mates to help.
I have an engine hoist/crane (not SGS but I bet they're all very similar.
I think your basic issue will be that it won't lift high enough to get the load onto the top of your car. The chain/rope/strap between the hook and the load will likely add too much length for the pad the clear the roof.
Adding an extension to the jib though is potentially "brave".
(You could counterweight it though I guess)
They are not trivial things to store either.
(But extremely useful on occasion)
I can have a look tomorrow though if you like.
Couple of pairs of hop ups or step ladders and just walk it on. I’ve put ours on the jeep. Jimny and type 2 this way.
They only weigh 30-50kg just lift and walk it up.
Don't confuse that engine hoist with the cheapest sgs/machine mart nonsense.
It's very much not. I can see how they managed. The lower legs are much longer than on the cheapest 1t models
To the OP if you've read the link that Trail rat posted I'd ignore it.
The amount of dangerous/useless advice on that site is scary!
The engine hoist idea is just ****ing stupid.
The heating of a RTT section is downright dangerous - {insert photo of a large propane industrial heater}, diesel heaters with no mention of dangers of the combustion gases.
Just get some mates / blokes from three local to lift it on.
I’ve got an sgs engine crane. I’m pretty sure it would not lift a roof tent high enough to put it on top of a car. At its furthest extension i think it will only lift 150kg. There must be an better solution.

I agree. That's the first link I found (with the dimensions the ops requiring)
Note curiously they don't ever actually show the hoist in action. You'd think that would be a key thing to show ?
Extended crane seems to work https://www.ebay.co.uk/itm/125963866493
This one looks the same and claims 500kg at full extension https://www.primetools.co.uk/product/sealey-tools-ph20-2-tonne-2t-hydraulic-engine-crane-hoist-lift/ .
I'd be concerned about flipping the crane forward though, with the load being in front of the wheels, even if it strong enough extrapolating from the above figures. It appears from the existing jib positions (1-3 and 3-4) that each 260cm halves the load capacity. So 0.75m extra and you're down to 63kg.
Evening all,
I have finally got the roof tent lifting system sorted using an SGS engine crane and lifting arm from Adventure Equipped. It works!!
Somewhat complex to get it sorted, need a low profile crane to fit under the car and slightly longer than standard slings to go round the tent.
Thank you to all above who took the effort to reply and provide advice. What I would say to some is please consider that the situations of others may not be the same as yours when providing advice :-). For some the option to 'just lift it', 'get some mates round', 'hang from the garage roof' are not practical so we have to think of other options.
I have a hard top roof tent and it is great for one or two night roadside stops in Scotland, very quick to useable in windy / wet conditions. I am looking forward to Spring though.....
Glad you're sorted.
If you hang on the crane will it flip? Just interested in how much safety margin there is.

Bunk by name, bunk by nature. 🙂
