I have a contractor who is planning on doing some dismantling work for us on a construction site. Part of the work requires some items (up to 1 tonne in weight) to be removed from there current position, some 35 ft in high, and be lowered to the ground.
Because our contractor already has a lorry with Hiab on site, he has stated that he plans to utilise the Hiab to lower these items to the floor.
The end client has stated that they are concerned that the Hiab is being used as they feel the Hi-ab is only designed and intended to load / unload items on and off the vehicle, and should not be used as a 'standard crane'. They feel that a seperate Crane should be brought in to do the work.
Can anyone confirm one way or the other if there is anything prohibiting the use of the Hi-ab?

Provided that the operation is within the load radius limits of the crane and the lift has been assessed by a competent person and adequately controlled it should not pose a problem.

I would go with the client on this one.
Equipment should only be used for the intended purpose.
If it fails and injures someone, will the courts look at it and say "it was reasonable to use a lorry as a crane?"
I would suggest the courts will not.
I would imagine there was an operator's handbook that came with the Hi-ab (somewhere...) and that would probably have a word or two on the subject. As the client, I would only permit this if the handbook specifically says it is ok.

Dear Tabs,
Thanks for that. In building my argument, do you know what guidance / legislation I could make reference to?
The contractor is arguing that the Hi-ab is in effect a crane and is being used well within it's SWL etc.

Paul,
As has been pointed out, if the correct procedures have been carried out no problem. Ask the Client what legislation is stopping the work being carried out in this way, consult with the CDMC to back up your position.

Take a look at Regulation 4 of PUWER 1998. Specifically guidance note 103 "... and that it is used in accordance with the manufacturer's specifications and instructions."
I doubt very much the manufacturer would describe the Hi-ab as a crane and underwrite its use in this manner ...
BUT ...
If the supplier of the lorry describes it as a crane suitable for operation other than load/unload then I agree with the other posters - but if it does not, I agree with the client.

I am with RP & Mitch on this one.
It is a lorry mounted crane. Have seen them used many times on site to lift engines out of caterpillar dozers, install equipment, etc.
Have a look at the hiab site, there are some good photos of them being used to lift stuff around site.
http://www.hiab.co.uk/Pr...Id=34360&productId=34374
Planned, undertaken and supervised by competent persons - no problem.
Why is there no facility for a poll on the site!

.. and I see scaffolders with their harnesses clipped to themselves whilst standing on three-storey scaff while still building the stuff. All the time. So that's right too?
As I wrote though, if it is an intended use then I agree with you too. No argument. :-)

Sorry Tabs, should have said "Have seen them used many times on site doing lifts that have been planned, undertaken and supervised by competent persons - to lift engines out of caterpillar dozers, install equipment, etc. safely"
A quick call to Hiab confirms this.

Nothing to stop the HIAB being used for lifting provided it follows the best practice guide BS7121 Part 4.

Just remember that Hi-Ab is a trade name, the proper name is a Crane Lift, with that in mind do you have a lifting plan for the works, produced by an appointed person?

Sorry
The proper name is a Lorry Crane and not Crane Lift.

If the client is specifying the way the works are to carried out has anyone explained that he may have duties as a designer under CDM 2007?

What's wrong with having a designer called Fred?
