Cleveland Tramrail products continue to reflect the quality that made Cleveland Tramrail the patented track leader, with the value added customer service and support that made Gorbel " A Class Above."

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.
