Tarca® Track For Durabilityand StrengthGorbel’s pre-engineered crane systems arebuilt using our unique patented Tarca® Track,which continues to be the benchmark of theoverhead material handling industry.

Its three piece welded construction is a com-pound section of a mild steel top flange andweb and a specially rolled high-carbon steellower rail. Tarca® systems are characterized byconsistently straight rail sections and durable,high quality Tarca® components. Our Tarca®

systems offer unmatched versatility, durabilityand ease of installation.

Tarca® Track has a mild steel top flange and web and a high carbon steel lowerrail with raised tread to resist peening.

Continuous welding adds rigidity need-ed to cope with bending and twistingstresses of the most demanding applica-tions.

The web and flange dimensions of each size are proportioned for maxi-mum strength and spanning efficiency.

Why Tarca® Track OverStructural Steel Track?A structural I-beam is rolled from soft, mildsteel according to fairly loose steel mill tolerances. Its beveled flange prevents wheelsfrom making balanced contact, causinguneven wear and a shortened track life.

Gorbel's unique Tarca® Track, with its specialraised tread and high carbon track, is superiorto I-beams in strength, durability and consistency. Our exclusive rails permit the useof:

• Underhung carriers operating on a singlestraight, curved or inclined track

• Underhung cranes operating on two ormore straight track runways.

TARCA® TRACK: ENGINEERED FOR CRANE APPLICATIONS

Strong, Durable RailTarca® vs. I-beam

High carbon flange means longer track lifeA common source of track wear is a process known as peening. Peeningis the gradual movement of metal over time, caused by the rollingaction of wheels. Because of I-beam’s mild steel construction, peeningtends to occur unevenly, weakening the beam flange and restrictingsmooth easy travel.

Tarca® Track’s raised tread design and extra hard alloy steel constructionslow down the peening process. The full width of the raised tread wearsevenly, extending track life well beyond that of I-beams.

Our raised tread provides durability and superior safetyThe raised tread on Tarca® Track is 20 - 25% of the Tarca® rail thickness.And though this does add some strength, our stress calculations do notinclude the strength added by the raised wearing tread. That means youget even more strength and dependability because the rated capacity ofthe track is not affected by wear.

Since I-beams have virtually no raised tread, their initial load carryingcapacity is in the total cross section. As a result, capacity and safety aregreatly reduced as soon as the tread begins to wear.

100% weld penetration ensures qualityTarca® 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 duringtrack fabrication to maintain dimensional tolerances. Our tracks arestraight 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 stringent quality standards in manufacturing guarantee consist-ently straight, high quality beams. Plate is cut to size and leveled by precision machinery. Special equipment uses continuous welds toinsure absolutely straight, uniform track. Standard mill practice dimensions for I-beams have tolerances more than twice those forTarca® rail. For example, allowable sweep per 10' of structural beammay 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 installa-tion: redrilling holes and cutting, fitting, and shimming rails in orderto align I-beams that aren’t straight. Our consistently straight railsresult in easy, predictable, cost effective installations.

Straight Rails Make System Expansions EasyThese tight quality standards even make system expansion and reorganization easier and more cost effective. Consistently straightbeams will reduce labor costs when you want to expand a crane system or rearrange a work area.

Peening caused the mild steel flangeon this I-beam (on right) to bend,making it completely unsafe for cranetravel.

Our Weight Is In All the Right PlacesEfficient Design for SpanningThe thickness and width of Tarca®’s weband flange for each size have been carefullyengineered to maximize strength and load-ing capability 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 a 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 materialhandling. Because of this, they are manu-factured to much looser mill tolerancesthan many crane and monorail applica-tions require.

Standardized Lower FlangeStandardized lower flange providescompatibilityTarca® track features the same 3-1/4” wide lower flange regardless of rail heightor 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 inwidth and thickness as its depth increases.Beams of different sizes are therefore not compatible. The result? I-beam cranesystems are costly and difficult to expandor relocate.

Rugged, Long LastingComponentsHardened wheels to ride on high carbon trackOur forged, heat-treated wheels are built to last. They provide years of smooth, easy movement and reliable service. Theyhave 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 andlonger life

• Engineered to avoid flat spots forsmooth, uniform rolling

Rugged end trucks and carriersGorbel® end trucks have been carefullyengineered to provide the finest perform-ance with little or no maintenance.

Extended drive lifeAll gears and shafts in Gorbel® drives aremade with a remarkable alloy-steel thatwas chosen after long, grueling tests.This special alloy allows the drives to holdup to the wear and tear of constant serv-ice. This adds many years of reliable serv-ice to the motor head.

Flexible SuspensionsFlexible suspensions provide longer system performance and lower maintenance costsTarca® Track is suspended using ball andsocket connections, permitting the trackto float in all directions. This means it cancompensate for structural movement byallowing tracks to move and adjust tocrane wheel centers. This:• Prevents damaging stress • Dampens shock loads• Allows for smoother operation

In other words, Tarca® rails can adjust toloads as they move, enabling carrierwheels to maintain consistent contact.This “load balance” of the wheels andcomponents allows for longer life withless maintenance.

Our Tarca® Track’sstandardized lowerflange provides compatibility.

Tarca® Keeps TruckMaintenance CompanyMoving

A Western New York company providesmaintenance and customization on heavytruck parts. Heavy parts weighing between1 and 3 tons are moved into the buildingand then 25’ across the building to a stag-ing area where they are worked on.

ProblemPrior to installing a Tarca® system, the com-pany was using fork trucks to move theparts, but the fork trucks were causingcongestion, parts damage, and safetyissues. The company was also looking tomaximize the floor space in the building sothey could make room for big trucks andparts, and they were hoping for a systemthat could be moved if needed.

SolutionThis company chose to install a 3-ton FreeStanding unbraced Tarca® system with a28’ bridge, 39’ runway, 16’ height underboom, and 37’ support centers.

Why was Tarca® the Smart Solution?The Tarca® system is free standing, and thesupports are close to the building walls,allowing room in the facility for safe move-ment and storage of trucks and parts.Because the system is not braced to thewalls, it can be relocated if the need everarises. Plus, using the crane system is muchsafer than using the fork trucks.

Crossover Track

1. Both bridge girders approach the crossover track. The operator pushes a but-ton powering a gear motor that activates a pair of rollers (see Photo 1).

2. The bridges line up with the crossover track. The rollers move from the interlocking beam toward a wedge type engaging mechanism on thecrossover track (see Photo 2).

3. The rollers make contact with the wedge and self-align within 1-1/4" horizon-tal range. As both beams are interlocked, forks on powered and non-poweredbeams are raised for free passage of carrier (see Photo 3).

4. To disengage the interlock, the operator pushes a second button. Motor driv-en rollers move back and away from wedge, allowing forks to drop and makecontact with rail tread. This prevents the carrier from travelling off the openend of the beam.

Electrification Options(Brackets, Collector Shoe and Bar)Gorbel® SAFPOWRBAR® Electrification isused to deliver electric power to drivesand hoists. This rugged, durable systemis made to perform in the mostdemanding applications and environ-ments. • Inverted U-shaped conductor bars

enclosed by flame resistant insulatedcovers.

• Fiberglass molded insulators for double insulation, making them saferand more efficient.

• Sliding current collector shoes insidethe bars make positive, continuouscontact with three surfaces of the bar for longer life and easier mainte-nance.

End StopEnd stops are required and must beprovided at the ends of the carrier ortrolley travel on bridges and at the endof crane travel on runways.

Our end stops are unique in that theystrike the end of the load bar, ratherthan the wheels. This prevents thewheels from absorbing the force of theload and reduces the areas of wear.

We offer standard wheel end stops forlighter applications and rubber, springor hydraulic bumpers for higher speedconditions.5
