Anyone know about hiab vehicles max lifting weight?
 

I'm looking into a hiab lorry that can lift site cabins, weight about 3 tonnes and 24x9ft wide.

Looking for a cheap vehicle and seen plenty but they never seem to list hiab lifting weight.

Anyone know about this sort of stuff?

All lorry loaders will be different depending on the type of lifting gear, lorry carrying capacity etc. All types of HIAB lifting gear must have clearly marked a SWL and have been inspected annually. If they havent don't touch them.

Can the container be loaded close to the lorry? The longer the boom has to stretch the weaker it gets. What I mean by that is, you could lift 10 tonne if the container is next to the lorry. If the container is say 10 foot away from the lorry it will only manage to lift 2 tonne.

So I was told :)

As above, quite correct, you need to know the heaviest weight your going to lift, and how far away you want to lift it.
For example.
an 18 metre ton hiab will lift 18 ton at one metre, or 1 ton at 18 metre:thumb:

Ok we are getting somewhere here.

The lorry can park right next to the cabins we have, thus the hiab would have to be over the middle so about 6 foot from the side of the lorry. The cabins are about 3 to 3.5 tonnes so am I right in saying say 4 ton at 2 meters would be a hiab at 8 ton or more would suffice?

Thanks, Chop

iirc they must state on the actual crane the maximum lift of each stage of the arm. obviously the more outstreched the arm the lesser the lift will be.

Spot on mate, as above they all need an up to date loler test, and marking on them , can't remember exactly what loler stands for, but it's basically lifting equipment regulations:thumb:

Lifting Operations and Lifting Equipment Regulations 1998

Most HIAB lifters will lift the cabin mass but what about the 4 leg chains? The angle they are often spread to means that they are used outside their SWL. You need to keep the included angle les than 90deg so the HIAB needs to be able to lift quite high.

Could you not just get a flatbed truck, and then chuck it on by hand ? Just remember keep your back straight and bend your knees :thumb:

As well as LOLER and PUWER, BS7121 will be worth a read. Particularly part 4 which covers lorry loaders. :thumb:

Hiabs come in all shapes and sizes. There will be a plate on the crane showing a couple of boom lengths and max loads. Assuming its been tested!

We've just hired a 30Te HIAB for a contract lift at work, it was a dedicated lift unit mounted on the back of a 3 axle tractor. Very impressive piece of kit :thumb:

The operator had a book of charts with him showing what weights he could lift to various reaches and various heights. There was an abridged version on a big label on the back of the cab.

Basically the further you get from the mounting plate of the jib, in any direction, the less you can lift. Whether or not the stabilising legs are deployed affects the lift capacity too.

As has been stated above, should you use one, check that all certification is current, for both the unit and the operator. You don't have small accidents when lifting equipment fails :eek:

Lifting can be a bit of a minefield if you don't know what you're doing, it seems pretty straightforward but things can go wrong real quick if the job isn't planned and executed properly.

I'm a qualified Crane Appointed Person and plan lifting operations every day. If you don't know what you're doing, get someone in who does. :thumb:

SF is right, lifting can be very dangerous if not carried out correctly.

Remember all of your lifting gear ie chains , slings etc also need to be certificated and tested as well, something that often tends to get overlooked.

A good HIAB will also limit your lift if the retractable legs are not extended far enough out so bear this in mind if when you say you can get the HIAB right next to the lift.

You will also need a Lorry loader ticket to operate the HIAB as well.

Which is why we always pay for contract lifts, leave the whole lot to someone who actually knows how to do it :thumb:
