What is a Tarca® System?
Cleveland Tramrail's unique patented Tarca® Track System continues
to be the benchmark of the overhead material handling industry.
Its three piece welded construction is a compound section of a
mild steel top flange and web and a specially rolled high-carbon
steel lower rail. Tarca® systems are characterized by consistently
straight rail sections and durable, high quality Tarca® components.
Our Tarca® systems offer unmatched versatility, durability
and ease of installation.

Why Tarca®
Track Over Structural Steel Track?
A structural I-beam is rolled from soft, mild steel according to
fairly loose steel mill tolerances. Its bevelled flange prevents
wheels from making balanced contact, causing uneven wear and a shortened
track life.
Cleveland Tramrail's unique Tarca® Track, with its special raised
tread and high carbon track, is superior to I-beams in strength,
durability and consistency. Our exclusive rails permit the use of:
|
|
• Underhung
carriers operating on a single straight, curved or inclined track
• Underhung cranes operating on two or more straight track
runways.
Tarca® Track has a mild steel top flange and web and a high
carbon steel lower rail with raised tread to resist peening. Continuous
welding adds rigidity needed to cope with bending and twisting
stresses of the most demanding applications.
The web and flange dimensions of each size are proportioned for
maximum strength and spanning efficiency.

Tarca Track: Engineered for Crane Applications
Strong, Durable Rail
Tarca vs. I-beam
High carbon flange means longer track life
A common source of track wear is a process known as peening. Peening
is the gradual movement of metal over time, caused by the rolling
action of wheels. Because of I-beam's mild steel construction, peening
tends to occur unevenly, weakening the beam flange and restricting
smooth easy travel.
|
Tarca ® Track's raised tread design and extra hard alloy steel
construction slow down the peening process. The full width of
the raised tread wears evenly, extending track life well beyond
that of I-beams.
Our raised tread provide durability and superior safety
The raised tread on Tarca® Track is 20-25% of the Tarca®
rail thickness. And though this does add some strength, our stress
calculations do not include the strength added by the raised wearing
tread. That means you get even more strength and dependability
because the rated capacity of the track is not affected by wear.
Since I-beams have virtually no raised tread, their initial load
carrying capacity is in the total cross section. As a result,
capacity and safety are greatly reduced as soon as the tread begins
to wear.
100% weld penetration ensures quality
Tarca® Track is manufactured using stringent quality assurance
procedures. This is the basis for certifying 100% weld penetration
for maximum strength, safety and rigidity. Extreme care is taken
during track fabrication to maintain dimensional tolerances. Our
tracks are straight and true with minimum distortion, so:
• Installs are quick and easy
• Load distribution is uniform
• Tracks and components last longer
Stop Throwing Away Your Installation Dollars!
Our straight quality standards in manufacturing guarantee consistently
straight, high quality beams. Plate is cut to size and leveled
by precision machinery. Special equipment uses continuous welds
to insure absolutely straight, uniform track. Standard mill practice
dimensions for I-beams have tolerances more than twice those for
Tarca® rail. For example, allowable sweep per 10' of structural
beam may be as high as 1/4" while Tarca® rail is less
than half that at 3/32".
Is It Really Cheaper to Use an I-Beam?
Consider the time and money you're throwing away during installation:
redrilling holes and cutting, fitting, and shimming rails in order
to align I-beams that aren't straight. Our consistently straight
rails results in easy, predictable, cost effective installations.
Straight Rails Make System Expansions Easy
These tight quality standard even make system expansion and reorganization
easier and more cost effective. Consistently straight beams will
reduce labor costs when you want to expand a crane system or rearrange
a work area.

Our
Weight Is In All the Right Places
Efficient Design for Spanning
The thickness and width of Tarca®'s web and flange for each
size have been carefully engineered to maximize strength and loading
capacity while minimizing weight. Tarca®'s three piece welded
construction:
• Delivers maximum load carrying capacity to dead weight
ratios
|
|
• Provides ability to cost effectively span longer distances
• Eliminates costly additional supporting structures
• Reduces drag in manual system
I-beam simply can not match Tarca®'s carrying capacity to
dead weight ratio. Structural I-Beams are manufactured for a purpose
other than overhead material handling. Because of this, they are
manufactured to much looser mill tolerances than many crane and
monorail applications require.
Standardized Lower Flange
Standardized lower flange provides compatibility
Tarca® track features the same 3 1/4" wide lower flange
regardless of rail height or load carrying capacity.
• Allows systems to be easily expanded or rearranged
• Ensures compatibility of components
• Lower costs when suspension points vary
The lower flange of an I-beam increases in width and thickness
as its depth increases. Beams of different sizes are therefore
not compatible. The result? I-beam crane systems are costly and
difficult to expand or relocate.

Rugged,
Long Lasting Components
Hardened wheels to ride on high carbon track
Our forged, heat-treated wheels are built to last. They provide years
of smooth, easy movement and reliable service. They have been:
• Designed to roll with minimal resistance (2 times easier than
I-beam)
• Machined to meet the surface of the track for consistent,
full contact and longer life
• Engineered to avoid flat spots for smooth, uniform rolling
|
Rugged end trucks and carriers
Cleveland Tramrail end trucks have been carefully engineered to
provide the finest performance with little or no maintenance.
Extended drive life
All gears and shafts in Cleveland Tramrail drives are made with
a remarkable alloy-steel that was chosen after long, grueling
tests. THis special alloy allows the drives to hold up to the
wear and tear of constant service. This adds many years of reliable
service to the motor head.
Flexible Suspensions
Flexible suspensions provide longer
system performance and lower maintenance costs
Tarca® Track is suspended using ball and socket connections,
permitting the track to float in all directions. This means it
can compensate for structural movement by allowing tracks to move
and adjust to crane wheel centers. This:
• Prevents damaging stress
• Dampens shock loads
• Allows for smoother operation
In other words, Tarca® rails can adjust to loads as they move,
enabling carrier wheels to maintain consistent contact. This "load
balance" of the wheels and components allows for longer life
with less maintenance.
