[Nhcoll-l] Self-levelling trolley - am I looking for a unicorn?!

Tue May 2 15:23:34 EDT 2023

Hi all,

can echo bad results with air filled tires: we replaced the hard rubber wheels at our cart with air-filled tires, but it turned out that these are less favourable when die cart is fully loaded with heavy jars (and the cart eventually stays loaded for 2-3 days): even though well pressured, the tires slightly deformed and started bouncing when the cart was moved.

After 3-4 weeks, we replaced them again. But maybe there are better air-filled tires then those I got from an DIY.

With best wishes
Dirk

For service in the move of the Florida Museum fluid collections and daily use beyond the move, we purchased ten carts with pneumatic tires. Both types had to be assembled -- easy to do, especially assembly line style.

This model from ULINE has performed very well:

The tires hold air nicely; stay inflated months at a time at good pressure.

The other model we purchased is this one:

One tire came with a faulty tube; the amount of effort I have put in to replace it is out of all proportion -- and I can't recommend the cart with pneumatic tires as a result. Also, the customer support from the vendor was, well, less than zero -- long online chats with multiple persons who could not so much as name the replacement tube or even wheel so that I might simply purchase a new one.

Eventually after patching the faulty tube -- and having it fail -- and after much searching for replacement tubes or even tires, replacement tubes were purchased from....Amazon.

Best wishes,

Rob

A gardening cart!  That is a great idea.

Hi Gretchen,

Some of our ichthyology labs had a big gardening cart with the large tiers which they took into the field. They let me borrow it once for moving material between buildings and it was lovely. The directional handle was really fine control as well.

I think our chemistry stock room has one they use now to make deliveries. If you want I can try and get a picture of the brand.

cheers,

Beth

Claire,

I agree with both Andy and Paul. The balloon /pneumatic tires are a good idea.  They would absorb vibrations on the floor.  At Science Museum of Minnesota we used heavy milk carton crates, padded with ethafoam to move many of our fluid collections in gallon jars. As I remember (it was a few years ago) we used our regular carts with lips on them to move the smaller jars, often packed in boxes with dividers.

How steep is the ramp?  That might determine if you need to get more complicated.

I’ve seen wagons with rigid metal sides (like a child’s Radio Flyer truck) and large balloon tires for use on uneven surfaces and sand. They could be used to move drums and tanks of fluid. You may be able to rent them from a site equipment rental place.

I think you are looking for something like this: https://www.southworthproducts.com/en/products/portable-lift-tables/dandy-levelers-self-leveling-portable-lift-tables<https://linkprotect.cudasvc.com/url?a=https%3a%2f%2fwww.southworthproducts.com%2fen%2fproducts%2fportable-lift-tables%2fdandy-levelers-self-leveling-portable-lift-tables&c=E,1,szJ1KhTGeJMYNpFuPma7jTBptwDaMN_HzgHEPpqKEPWcdVJukI9q_z8BxsxsDABcowbh_DHr6UizjFjQVU0s0EchdXPFWOhiO9JS1EqoQW6A60k1&typo=1>.

I have never used one before but just looking at it I would not think it would be safe for transporting fluid materials unless you could find one with a lip that would prevent materials from falling off.  Depending on the grade of your ramp, I would not think it would be too unsafe to use a regular low level cart and place all jars into crates or boxes and secure them to the cart.

If you really need one of these, there are lots of different suppliers who make these in various sizes  but none are cheap.

Hope that helps

Andy

Hi Everyone,

We are in the process of moving our fluid collection to a new location, a university building is being refurbished for us.

Entry to the building is currently via a sloping fire exit ramp, which is not ideal.

The contractors have told us that we need a “self-levelling trolley”.

Have any of you heard of such a thing? Have you used one? Could you recommend one?

Would it be safe for transporting fluid specimens?

Yours in confusion,
Claire
