<div class="moz-cite-prefix">Hi Rob and all,</div>
<div class="moz-cite-prefix"><br>
</div>
<div class="moz-cite-prefix">we don't have such trenches, but a
slightly uneven floor and uneven door sills. Be careful with
pneumatic (larger) rubber tires; as John pointed out fully loaded,
heavy carts can deform the tires, especially if the payload
remains on the cart, e.g. over night, the tires might be deformed,
even if inflated to the max. The same applies to some full rubber
wheels. We replaced wheels again and equipped our cart with larger
fixed rollers for heavy loads. The steel centre and the rather
sturdy and slim rubber hoop surely to not support the smooth
wheeling, but these wheels are a fair compromise.</div>
<div class="moz-cite-prefix"><br>
</div>
<div class="moz-cite-prefix">In the Brussels collection they have
deep trenched tiles on the floors in the collection space, carts
in the old carts in the collection (surely also form the 1930ies)
have very large steel wheels with rubber hoops. They run rather
smoothly, which is because of the large wheels.</div>
<div class="moz-cite-prefix"><br>

<div class="moz-cite-prefix">Hope this helps</div>

<p class="MsoNormal">I agree with John that carts with
larger-diameter wheels are a good idea. You can often
retro-fit existing carts with bigger wheels. They don’t need
to be pneumatic as long as they have rubber tires; the
diameter is the main thing. However, bear in mind that every
extra inch of wheel diameter (and soft tires) makes the cart
easier to tip, especially if it is loaded with heavy jars on
the top. It’s best either to use a lower cart or to load
things on the bottom shelf.

<p class="MsoNormal">I think the ideal wet collection wagon is –
yes – the Radio Flyer! It has a tall rim to stop bottles
tipping, is watertight if anything leaks, has nice big wheels
and a long steering handle and is reasonably priced.<o:p></o:p></p>
