- Specialties & Categories
The Used Equipment Network uses a hierarchical system to classify
equipment because of the very large number of items available on the site.
The first level is the "major specialty". This describes the
type of equipment in very general terms, like "metalworking"
or "medical". This level is designed to get you into the
right ballpark for the equipment you need.
Many of the major specialty areas also have "sub-specialties"
under them as a second level. For example, under the general
area of metalworking, we have sub-specialies for "grinding",
"brakes & folding", "machining center", and
many others. Listed under the general heading of "material handling"
we have sub-specialties for "cranes & hoists" and for
"lift trucks & carts" among others.
The final level of detail is the UED Category. The category system
was developed by Used Equipment Directory and has been the standard
in the used equipment industry for many years. These are alpha-numeric
identifiers that are quite specific to the equipment; Examples are
L3000 which is "Lathes, Engine" and C6575 which is
The assignment of categories to specialties is not unique. Category M0130
(Machining Centers, Horizontal, CNC) appears under both the sub-specialty
for machining centers and that for CNC equipment. H5000 (Hoists) appears
under both the material handling specialty and the construction specialty.
This makes it easier to find the equipment you need or the category
under which a listing should be entered.
It is not necessary to know either the specialty number or category code
to locate equipment on the system, but if you frequently look at a
particular type of equipment you can go immediately to those listings
from the main page of the site if you know the category.
For each of the over 2000 categories in the system, we have assigned the
appropriate sort/search fields. As examples, lathes are measured primarily
by swing and center distance which machining centers are measured by the
X, Y, and Z travels. A hoist is measured by capacity in tons and maximum
lifting distance, while a tranformer might be measured in KVA and primary
and secondary voltages.
