When the fluid preserved specimen facility at the University of Kansas was built, we were required (by the university safety office) to purchase safety ladders to access the upper shelves. Although we thought these would be a problem, they actually worked very
well and are still in use more than 25 years later. </div>

The style we purchased are similar these--rolling ladders, with the wheels on springs, and a platform and railing:</div>

As Dirk mentioned, the most important thing is to match the ladder to the width of the aisles and the width of the area where the ladders are to be turned around. Even the narrow 25 inch wide ladders (such as are in use at KU) cannot be turned around within
the aisle, but this is not a problem--just as with compactors, you quickly adjust your work habits to accommodate moving the ladders and opening and closing aisles. The ladders need a fairly wide space to be turned around, so make sure the ladders you purchase
will fit your space. We cut a shape of the base of a ladder out of cardboard and used that to make sure the ladders could be easily wheeled about and turned around in your space.<br>

<div class="gmail_default" style="font-family:tahoma,sans-serif;font-size:small;color:#000000">
Another important factor is to adjust the springs so that the weight of the lightest person using the ladders will cause them to settle on the floor. If they are adjusted for heavier people only, the ladders can slide.</div>

</div>
<div class="gmail_default" style="font-family:tahoma,sans-serif;font-size:small;color:#000000">
We also found that having the railing around the platform is very useful for moving boxes or, in your case, heavy trays.</div>

If you have any questions about using safety ladders in your collection space, you might want to check with Andy Bentley at the University of Kansas, who has now used the ladders longer than I did while there.</div>

<p class="MsoNormal">I am wondering if any of you have ladder recommendations that you would be willing to share. We are moving to new taller cabinetry for our study skins. The trays are also quite heavy, as they are large and made of powder coat steel. I think
I would like some ladders that have a moveable platform on them, in order to be able to retrieve trays from height and then lower them down mechanically. Ideally, they would also be manoeuvrable so that we could easily get them down aisles and around corners
in very full collection halls. Any thoughts or recommendations on something like this, or alternatives I should look into, would be greatly appreciated!<u></u><u></u></p>
