Well according to my experience i had numerous dollies destroyed. i’m going to write and pros and cons on each dolly type that i have used before :
i had several of these folding hand type dolly around 3 of them and at first i have a great time with it but it will never last for 3 months, problems is the springs attached to the steel rod comes off and most of time are the steel wheel it gets misaligned and its gets dented to a hollow point that it is beyond repair.
this type is very sturdy but the downside is that if you have a cargo van it occupies a lot of space and sometimes you have to deal with flats.
?
this is great dolly which i got it from Canadian Tire and made by Cosco, it is a 3 ways dolly, and it is part aluminum which is very light, the 1st problem that i can live with is the top portion black plastic internal spring holder got broken and couldn’t be fixed so the 2nd way posts keeps on dropping and cannot be locked, i lived with it for 1 year since it is a minor problem and the 2nd problem that came along is the sides hinges got broken, i was able to live with it for about 2 years! by the way not to mention one of the wheels came loose and got flat and had the replace the wheel assembly
i recently was contemplating on getting this type of dolly which i found at The Home Depot but the problem again that i foresaw was there were steel clips on the side that without it the dolly will not function as a 2 way, so i just forgo with it.? At home depot i saw this dolly without steel clips on the side, i assumed that someone loss those steel clips and stole it or perhaps the design is not very good that the steel clips just loose.
this type of dolly cannot be used for vending because the bottom gets broken easily with a few cases of pop, so you should scratch the idea of lightweight foldable dolly since it doesn’t look sturdy at all.
i recently got a shifter 2in1 hand truck dolly on sale from canadian tire for $59.99, its very lightweight and i can put it anywhere inside the cargo van and so far im very happy with it, i just used it today and its quiet, no flat wheels. i still do not know the problem with this dolly but i sense that this cannot be pulled moved on stairs because of the smaller wheels but i can always move the load on the stairs first.? the advantages so far outweighs the disadvantage.
Update
This is an update , recently the wheels beneath the shifter 2 in 1 dolly gave way and it only lasted for me around 2 months of usage and it is not as sturdy as i thought.
Presently im using a dolly with no problems so far and it only costs me about $100 canadian to buy it from Home Depot and here is a similar picture :
?Mine is the stainless steel version with bigger inflated wheels as compared to this picture.
In case if you wanted to move your vending machines to locations then you will be needing another kind of dollies.
