Need some heavy duty plant caddys

Hello all and happy new year

I'm after some advice/suggestions please. I have lots of heavy containers outside which I'm finding it harder and harder to move, so I want some wheeled plant caddys to put them on. They would need to be heavy duty and fairly large, but because I need quite a few I'm looking for something reasonably priced.

I've posted some links below to a couple I've found, but they're both in the States and very expensive.

Any idea where I can get something similar (but cheaper) over here? They don't need to be round.

Alternatively I've thought about making my own by attaching some sturdy wheels to some wood. Any idea what sort of wheels/wood I'd need?

Thanks in advance

This any help? https://www.google.co.uk/search?q=Plant+Dolly&ie=utf-8&oe=utf-8&gws_rd=cr&ei=ofCnVLCcCIOsadmngZAM

 

Might be simpler and cheaper to just buy a good solid sack barrow.
I can just visualise plants on wheels moving around the garden on a windy day.

 

Or moving around the neighbourhood under 'thieving toe rag' power.

 

Can you get peat liners that fit shopping trolleys?

 

Thanks @NigelJ - I've done some Googling but can't find anything reasonably priced unfortunately

I have a trolley but have trouble getting the containers onto the trolley as they are so heavy (some of them are 90L containers, so very large and heavy).

 

How about putting some of these under your existing, http://www.espares.co.uk/product/es...&plid=&pdv=c&gclid=CPHToeCW-MICFRMatAodQ2wA6Q

They got brakes on them.

They have a screw hole in the centre so I could fasten a piece of wood across to join them. Only problem would be that the wheels don't swivel.

 

I've used them on fridges, you can turn things, just takes a bit of space, bit like tacking with a sailboat
