Free Standing Work Station
Bridge Cranes

 
 
The safe, productive, ergonomic solution for
overhead materials handling operations.
Enclosed Track Design Makes for Easy
Movement and Long Life
Free Standing Work Station Bridge Cranes The steel Work Station Crane System 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 feet with
   steel truss design). This reduces the possibility of the
   support columns interfering with the work cell layout.
• Four distinct sizes of track -- 250, 500, 1000, and
   2000 series -- enable you to keep bridge weights
   and costs to a minimum.

Rigid Runways Provide for Superior
Positioning of Loads
The 2° taper of the running
flange helps to center the
trolley in the track for smooth,
effortless movement of trolleys
and end trucks.

Work Station Bridge Cranes are installed so that the
runways are rigid. They do not move laterally or
longitudinally. In addition, the 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 runways, 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 cost.

What is meant by Rated Capacity?
The rated capacity is the live load that can be lifted by
the crane system. The design load for the crane system
is based on the rated capacity plus 15% for the weight
of the hoist and trolley (capacity x 1.15) and an additional
25% for impact (capacity x 1.25) for a total design of
capacity x 1.4 (Note, 25% impact factor is good for
hoist speeds up to 50 f.p.m.). For example, a 1000 lb.
crane allows you to pick up a 1000 lbs. load, provided
the hoist weights 150 lbs. or less and the hoist speed is
less than 50 feet per minute.
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 need for
frequent hangers. Model numbers start with: GLCS-FS
for spans up to 20 feet, GLCSL-FS for spans up to 25
feet, and GLCSLX-FS for spans up to 30 feet.

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
these Work Station Cranes are among the most versatile
to apply and easiest to install in the industry.

Design load for deflection calculations is based on
the rated capacity plus 15% for the weight of the hoist
and trolley (capacity x 1.15). Under no conditions should
the crane be loaded beyond it rated capacity. Work
Station Cranes meet or exceed the ANSI B30.11
specifications for underhung bridge cranes.
 
Mixed Capacity Bridge Crane Systems: Easy to Install
Reduced bridge dead weight equals better ergonomic
solutions.
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).
Mixed-capacity systems allow multiple lower capacity
bridges to be used on higher capacity runways, provided
the equivalent center loads (ECL) are verified at the
factory to ensure that runways and hangers are not
overloaded. For example, using mixed-capacity end
trucks, four 500 lb. bridges (utilizing 500 series rail)
can be hung from a 2000 lb. runway, allowing side-by-
side use of all four bridges without overloading the
system. By mixing bridges of various sizes and cap-
acities, mixed-capacity systems offer reduced bridge
dead weight, easier movement, and reduced cost.
Modular Design
The 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.

Anatomy of a Work Station Crane
anatomy of a work staion crane hoist trolleys
1 HOIST TROLLEYS
Hoist trolleys provide the connection between the lifting
device and the monorail. The trolleys are designed for
effortless movement along the track. The stamped body
fits most rigid hook or eye lifting devices.
• Wheels are tapered to match the 2° taper of the track.
   This reduces rolling resistance and wheel wear. Wheels
   contain ball bearings that are sealed and lubricated for
   life.
• Trolleys are designed to operate in temperatures from
   +5° F to +200° F.
• All trolleys meet or exceed the ANSI B30.11
   specification for underhung bridge cranes.

END TRUCKS
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° taper of the track,
   which reduces rolling resistance and wheel wear.
   Wheels contain ball bearings that are sealed and
   lubricated for life.
• Two horizontal wheels center the end truck within the
   runway which prevents binding of the bridge. As a
   result, the position of the load on the bridge has little
   effect on the amount of force needed to move the
   bridge along the runway.
• Any slight runway track misalignment is taken up by the
   bridge floating in one end truck, while the other end
   truck is firmly clamped to the bridge.
• All end trucks meet or exceed the ANSI B30.11
   specification for underhung bridge cranes.

FESTOON GLIDES
Festoon gliders are used to support flat cable along the
monorail, and they are standard on monorails of 63 feet
or less. No tools are required to attach the festooning to
the gliders.
festoon trolleys

FESTOON TROLLEYS
Festoon trolleys (optional) are used to support flat cable
or air hose along the monorail. The trolleys have four
wheels and a pivoting festoon saddle support. They are
ideally suited for long runways (greater than 63 feet) or
with round cable or air hose. With monorails greater than
63 feet or with an all aluminum system, festoon trolleys
are standard. Special festoon trolleys for vacuum hose
are also available.
festoon clamps

FESTOON CLAMPS
Festoon clamps anchor the festooning at the start of the
monorail. They also prevent the festoon gliders from
exiting the track and they can provide a redundant stop
of the trolley.
end stop bumpers

END STOP BUMPERS
High-impact molded end stop bumpers are provided on
all monorails, to prevent the trolley from exiting the
track. The bumpers are bolted to the track to physically
limit the travel of the trolley.
universal bumpers

STACK SECTIONS
A stack section at one end of a monorail serves as an
extension that allows festoon carriers to be stored on the
end of the monorail without reducing hoist coverage.

FLAT CABLE AND/OR AIR HOSE
A flat cable festooning system is included in all
monorails. Plenty of cable is provided for 3 foot loops
on the monorail.
Optional air hose is also available and is supported by
optional festoon trolleys.
Optional air hose is also available and is supported by
optional festoon trolleys. Work Station Cranes can utilize
optional conductor bar electrification, but this results in
an increase up to 40% of the amount of effort required
to move the system.
hanger assemblies
10
HANGER ASSEMBLIES
Each Work Station Bridge Crane is provided with the
appropriate number of hanger assemblies, based on the
number of support assemblies shown on the dimensional
section.
Hangers for Trussed Steel Track
Hangers for steel runways are included with each
assembly as shown. The runways are flush mounted
under the free standing support assemblies via spine
clamp angles, B7 alloy threaded rods, and the appropriate hardware.
slpice joints for steel tracks
SPLICE JOINTS FOR STEEL TRACK
A splice joint is used to join track sections together
and enable the installer to quickly and properly align
the joined sections of track. Adjusting bolts are
provided on the splice joint for leveling and aligning.
