Product Features
Enclosed Track Design Makes For
Easy Movement and Long LifeBoth the aluminum and steel Gorbel Work
Station Crane Systems utilize enclosed track
that is high in strength and low in weight.
Major advantages:
• Enclosed track cranes are up to
three times easier to move than
traditional bridge cranes.
• The design virtually eliminates dirt
and dust from the rolling surface,
thus reducing wear on the wheels
of the trolley and end trucks.
• The smooth running surface means
lower rolling resistance.
• The low profile of the steel track
allows the system to be installed
where headroom is a problem.
• The low track weight reduces the applied
forces exerted on the supporting structure.
• Long spans allow systems to be installed where support
assemblies are infrequent (up to 30’ with steel truss design).
This reduces the possibility of the support columns interfering
with the work cell layout.
• Four distinct track sizes -- 250, 500, 1000, and 2000 series --
enable you to keep bridge weights and costs to a minimum.
Trussed Steel Track:Permits longer spans, which allows more flexibility in crane layout.
The trussed series uses the plain steel track profile but is enhanced for
longer spans via a built-up truss design. This design increases the span,
which decreases the frequency of hangers. Model numbers start with:
GLCS-FS for spans up to 20’, GLCSL-FS for spans up to 25’, and GLC-
SLX-FS for spans up to 30’.
Long spans translate into fewer runway support points, less interference of
work cell layout, longer bridge lengths, and free standing capabilities...just
another reason why Gorbel Work Station Cranes are among the most ver-
satile to apply and easiest to install in the industry.
Aluminum Track:For use when lower bridge weight and easier movement are required.
The patented shape of Gorbel’s aluminum enclosed track provides for low
weight, unparalleled spanning capability, and effortless movement.
The low weight (up to 44% less than trussed steel track) results in easier
movement, which makes for safe, productive, ergonomic work cells.
Runway spans up to 20’ and bridge lengths up to 34’ meet a wide range of
applications. Model numbers start with AL-FS.

Product FeaturesRigid Runways Provide Superior
Positioning of LoadsGorbel Work Station Bridge Cranes are installed so that the
runways are rigid. They do not move laterally or longitudi-
nally. In addition, Gorbel’s floating end trucks with horizontal
wheels prevent binding. The combination of these design
features results in unmatched ease of positioning and ease
of movement. The bridge travels smoothly down the run-
ways, and movement is unvarying along the way, no matter
where a load is positioned on the bridge. This allows
superior load positioning.
Another advantage of rigid runways is that runways double
as stringers between support columns. This eliminates the
need for expensive intermediate support stringers, and it
lowers overall installation costs.
Easy to InstallGorbel Free Standing Work Station Bridge Cranes can be installed on any normal 6” reinforced concrete floor. Each
column is anchored by four bolts, thus eliminating the need for field welding.
Support columns are designed to AISC specifications. If no movement of the support assemblies is required, then
bracing to the building is recommended (not included).
Modular DesignThe pre-engineered modular kit design permits easy expansion or relocation. The runway length can be increased by
adding runway sections, free standing support assemblies, and additional bridges as needed.
Featured Case StudyIndustry:
Airport Support Vehicles
Application:
This customer needed cranes to lift and place heavy items in vehicle
assemblies as they travel through an assembly line. The line contained
6 work stations where workers had to assemble and move 4000 lb.
loads at their own pace.
Gorbel® Solution
This customer chose to install a Gorbel Free Standing Work Station
Bridge Crane with six 4000 lb aluminum bridges. The customer had
considered conventional electric driven cranes because they used them
in other parts of their facility.
Why Gorbel® Was The Smart Solution
The customer chose a Gorbel® system because it allowed them to move the 4000# loads very easily and faster than
the conventional cranes due to the ability to cover both horizontal axes at the same time. The customer is very
pleased with the system they chose. Production on that assembly line has increased 25%.

Ergonomic Study ResultsIn a study performed by the Rochester Institute of Technology, manually operated, traditional I-Beam cranes were com-
pared to Gorbel® Work Station Cranes (WSC) in relation to push and pull standards developed by Snook and Cirello
(1991) for consideration by NIOSH.
5
Figures 3 and 4.
Part One compared the Snook and Cirello guidelines with the type of push/pull forces experienced in industrial conditions on I-Beam
and WSCs. Given the data, it is evident that only a small portion of the workforce can handle a 4000 lb. load on an I-Beam
crane,while almost any worker, male or female, can handle 4000 lb. on a Gorbel® WSC.
Figures 1 and 2.
Part Two determined the difference in productivity for both types of cranes. Reduced dead weight and a design superior to that of
the I-Beam crane result in reduced coefficients of friction and lower initial and sustained movement forces that allow workers to
position and move loads on Gorbel® WSC’s more easily than on I-Beam cranes.

Anatomy of a Free Standing Work Station Crane
Hoist Trolleys
Gorbel’s hoist trolleys provide the
connection between the lifting
device and the bridge. The
trolleys are designed for effortless
movement along the bridge. The
stamped body fits most rigid hook
or eye lifting devices.
End Trucks
Gorbel end trucks provide the connection
between the bridge and runways. They are
designed for effortless movement along the
runway. Wheels are tapered to match the 2
degree taper of the track, which reduces
rolling resistance and wheel wear.
Festoon Gliders
Festoon gliders are used to
support flat cable along the
runway and bridge. They
are standard on steel
runways of 63’ of less. No
tools are required to attach
festooning to the gliders.
Festoon Trolleys (optional)
Gorbel festoon trolleys are
used to support flat cable or
air hose along the runway or
bridge. The trolleys have four
wheels and a pivoting festoon
saddle support.
Festoon Clamps
Festoon clamps anchor the
festooning at the start of the
runway and bridge and
prevent the festoon gliders
from exiting the track.
Universal Bumpers
A universal bumper
can be used as an
intermediate end stop,
primarily for zoning
purposes.
Stack Sections
A stack section at one end
of a runway serves as an
extension that allows
festoon carriers to be
stored on the end of the
runway without reducing
crane coverage.
Hanger Assemblies
Each Gorbel Work Station Bridge Crane is provided with the appropriate
number of hanger assemblies, based on the number of support
assemblies.
