Enclosed Track Design Makes for
Easy Movement and Long Life
 
ceiling mounted bridge cranes and monorails  
The steel Work Station Crane Systems utilizes
enclosed track that is high in strength and low in
weight. Major advantages:
• Enclosed track cranes are 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 hanging points are infrequent (up to
   30 feet with the steel truss design).
• Four distinct sizes of track -- 250, 500,
   1000, and 2000 series -- enable you to keep
   bridge weights and costs to a minimum.
 
PLAIN STEEL TRACK :
For use where frequent support
points are available or where
maximum headroom is required.
The standard cold-rolled steel track
profile offers a low-weight to
high strength ratio. Model numbers
start with GLC (for bridge cranes)
and GLM (for monorails).		 plain steel track
The 2° taper of the
running flange helps
to center the trolley in
the track for smooth,
effortless movement of trolleys
and end trucks.
Plain Steel Track
trussed steel track
TRUSSED STEEL TRACK:
Permits longer spans when frequent support points are not available.
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 (for bridge cranes) and GLMS
(for monorails) for spans up to 20 feet; GLCSL or GLMSL for spans up to 25 feet, and
GLCSLX or GLMSLX for spans up to 30 feet.
Long spans translate into fewer runway support points, longer bridge lengths, and freestanding
capabilities... just another reason why Work Station Cranes are among
the most versatile to apply and easiest to install in the industry.

Rigid Runways Provide for Superior
Positioning of Loads		 Calculating Applied Forces to the
Supporting Structure
This illustration shows the relative position and the
direction of forces that a ceiling-mounted bridge crane
applies to its supporting structure. Before installing any
crane system, it’s critical that you determine whether
your building will safely support the loads.

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.
Loads applied to the support structure can be
determined using the following formulas, where:
ceiling mounted bridge cranes and monorails
Another advantage of rigid runways is that they can
be reinforced (trussed “S" series), so they are useful
where long spans are required. This eliminates the
need for expensive intermediate support stringers,
and it lowers overall installation cost.
Mixed Capacity Bridge Crane Systems:
Reduced bridge dead weight equals better
ergonomic solutions.
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 capacities,
mixed-capacity systems offer reduced bridge
dead weight, easier movement, and reduced cost.
R1 = vertical load applied by support hanger (lb.)
R2 = longitudinal load applied by movement of the
crane to each runway (lb.)
R3 = lateral force applied by movement of the trolley
and load to each runway (lb.)
L1 = distance between support centers (ft.)
(NOTE: If there are only 2 supports/runway,
L1= L1 x 0.5)
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 lb. load, provided the hoist weighs 150 lb.
or less and the hoist speed is less than 50 feet per
minute.
L4 = bridge span: center line distance between
runways (ft.)
P = live load capacity (lb.)
1.4 = design factor (see description below) which
includes 25% for impact and 15% for assumed hoist
and trolley weight
W = weight per foot of runway (lb./ft.) See installation
guide below
w = weight per foot of bridge (lb./ft.) See installation
guide below
R1 = 1.4 x P + (W x L1) + (w x L4)
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 its rated capacity. Gorbel Work
Station Cranes meet or exceed the ANSI B30.11
specifications for underhung bridge cranes.

Anatomy of a Work Station Crane
anatomy of a work station 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.
2
 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 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 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.

 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.
