Tarca® Track For Durabilityand StrengthGorbel’s pre-engineered crane systemsarebuilt 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® systemsare characterized byconsistently straight rail sections and durable,high quality Tarca® components. Our Tarca®systemsoffer unmatched versatility, durabilityand easeof installation.

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

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

The web and flange dimensionsofeach 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 milltolerances. 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 andconsistency. Our exclusive rails permit the useof:• Underhung carriersoperating on a singlestraight, curved or inclined track

• Underhung cranesoperating on two ormore straight track runways.

TARCA® TRACK: ENGINEERED FOR CRANE APPLICATIONS

Strong, Durable RailTarca® vs. I-beamHigh carbon flange means longer track lifeA common source of track wear is a process known aspeening.Peeningis the gradual movement of metal over time, causedby the rollingaction of wheels. Becauseof 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 providesdurability and superiorsafetyThe raised tread on Tarca® Track is 20 - 25% of the Tarca® rail thickness.And though this does add some strength, our stresscalculations do notinclude the strength added by the raisedwearing tread. That meansyouget even more strength and dependability becausethe 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 crosssection. Asa result, capacity and safety aregreatly reduced as soon as the tread begins to wear.

100% weld penetration ensuresqualityTarca® Track is manufactured using stringent quality assuranceprocedures. This is the basisfor certifying 100% weld penetrationfor 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• Tracksand 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 sizeand leveled byprecision machinery. Special equipment usescontinuous welds toinsure absolutely straight, uniform track. Standardmill practicedimensions for I-beams have tolerances more than twice those forTarca® rail. For example, allowable sweep per 10' of structural beammay be ashigh as1/4'' while Tarca® rail is lessthan half that at 3/32''.

Is It Really Cheaper to Usean 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-beamsthat aren’t straight. Our consistently straight railsresult in easy, predictable, cost effective installations.

Straight RailsMake SystemExpansionsEasyThesetight quality standards even make system expansion andreorganization easierand more cost effective. Consistently straightbeams will reduce labor costswhen you want to expand a cranesystem or rearrange a work area.

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

Our Weight IsIn All the Right PlacesEfficient Design for SpanningThe thickness and width of Tarca®’s weband flange for each sizehave been carefullyengineered to maximize strength and load-ing capability while minimizing weight.Tarca®’s three piece welded construction:• Deliversmaximum load carrying capacityto dead weight ratios

• Providesability to cost effectively spanlonger distances

• Eliminatescostly additional supportingstructures

• Reducesdrag in a manual systemI-beam simply can not match Tarca®’scarrying capacity to dead weight ratio.Structural I-Beamsare manufactured fora purpose other than overhead materialhandling. Becauseof 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 regardlessof rail heightor load carrying capacity.• Allows systemsto be easily expanded orrearranged

• Ensurescompatibility of components• Lower costswhen suspensionpoints varyThe lower flange of an I-beam increasesinwidth and thickness as its depth increases.Beamsof different sizesare thereforenot compatible. The result? I-beam cranesystemsare costly and difficult to expandor relocate.

Rugged, Long LastingComponentsHardened wheelsto ride on highcarbon trackOur forged, heat-treated wheels are builtto last. They provide yearsof smooth,easymovement and reliable service. Theyhave been:• Designedto roll with minimalresistance (2 times easier than I-beam)

• Machined to meet the surfaceof thetrack for consistent, full contact andlonger life

• Engineered to avoid flat spots forsmooth, uniform rolling

Rugged end trucksand 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 suspensionsprovide longersystemperformance and lowermaintenance 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:• Preventsdamaging stress• Dampens shock loads• Allows for smoother operationIn 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 withlessmaintenance.

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’ acrossthe 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 spacein 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® systemwith a28’ bridge, 39’ runway, 16’ height underboom, and 37’ support centers.

Why was Tarca® the Smart Solution?The Tarca® systemis free standing, and thesupports are close to the building walls,allowing room in the facility for safe move-ment and storage of trucksand parts.Becausethe 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 crossovertrack. The operator pushesa but-ton powering a gear motor that activatesa pair of rollers (see Photo 1).

2. The bridges line up with the crossovertrack. The rollers move from theinterlocking beam toward a wedge type engaging mechanismon thecrossovertrack (see Photo 2).

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

4. To disengage the interlock, the operator pushesa secondbutton. 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.
