Mobile pallet racks are
driven by electric motors so that each aisle can be opened up to access
individual pallets. This allows a higher storage density compared to a static
aisle system. However, it is not possible to access every aisle simultaneously
in this system.
The racking applies point
loads to the rails and, depending on the stiffness and fixing arrangements of
the rails, they either apply a point load or a line load to the slab.
These systems can reach up
to 13m in height. The rails can run up to 90m and support up to 24 tons, making
this a very versatile storage option.
Care must be taken with these systems to reduce risk of dynamic sway whilst
the racking is in motion, as this could result in instability of the goods near
the top of the racking.
