TRACTOR ENGINEERS LIMITED

Tractor Engineers Limited. (TENGL) founded in 1963, is a wholly owned subsidiary of Larsen & Toubro Ltd.

TENGL manufactures crawler Undercarriage and track parts at its modern factory at Powai, Mumbai. TENGL maintains product excellence by exercising strict quality control in its manufacturing activity. Quality standards comply with ISO 9001-2000. A fully integrated ERP system SAP ensures a well tracked manufacturing cycle for all TENGL items.


TENGL…committed to Customers needs.

Over the years, TENGL has acquired a professional identity as a dependable source of products, services and parts. TENGL continues to make a major investment in upgrading its manufacturing base and R&D facilities as part of its enduring commitment to customer needs.
TENGL's Research and Development Center is engaged in product upgradation. R&D engineers interact closely with customer personnel. Application engineering services include:
• Identifying problem areas.
• Defining the nature, cause and consequences of the problem.
• Offering the optimum solution.

TENGL…proven technology for reliable performance.

All TENGL personnel share quality consciousness. TENGL uses Boron Steel to combat wear and tear of undercarriage parts and components. This die-hard steel has tremendous impact strength coupled with wear resistance.

Quality control measures are integrated into TENGL's production process. Checks e.g. microstructure analysis, non-destructive testing- magnaflux, periodic sampling at various stages…ensure conformance to customer specifications.

Surface hardness in TENGL parts is precisely matched. The core hardness is carefully controlled to produce parts that are tough, resist wear and serve longer.

High dependability of parts is attributed to the special alloys, selective heat treatment and exclusive know-how. Track components are so designed that worn parts can be rebuilt, more than once, to a like-new condition and reused just as effectively.

That's why you can be certain that with TENGL's rebuildable track parts you can conserve and reduce expenses on replacement of spares.


Grease filled Link Assembly :

As an improvement over conventional sealed type L.A. TENGL has developed greased filled L.A. Such L.A. yield longer wear life by reducing the rate of internal wear between track pin and track bushing. Extreme pressure grease is packed in the annular space between pin and bushing at the time of assembly; to retain the grease and prevent foreign particles from entering the lubricated cavity special polyurethane seals are used.

Grease filled L.A. of a particular size is interchangeable with corresponding sealed L.A.



Links.

Links are forged from deep hardened steel and have massive-strut and increased rail height. A generous blending radii in these links increases their fatigue strength, reduces the possibility of cracking and offer excellent rebuilding. The link body is also specially hardened to impart toughness.

The rail surface is induction hardened to match the roller flange hardness. TENGL link's hardened depth shows consistency not present in competitor's links. The Result: TENGL links are stronger by almost 22% compared to low rail design.

Pins and Bushings.

Pins are characterized by exceptional core strength that minimizes case crushing and deep & even case depth for long life and strength before and after turning. Bushings have tempered ends, which eliminate cracking breaking during assembly and disassembly.

Roller Group.

TENGL rollers match the tracks. Shafts are induction hardened and ground to near perfect smoothness. The thick flanges have an excellent load carrying capacity. Rims are also selectively hardened so that you have a hard, deep case coupled with a tough core. The Result is reduced shell wear, no bending, no bell mouthing or breaking.

Metal Faced full floating seals keep TENGL rollers lubricated for life. Make up lube servicing or flushing is never required. These rollers not only perform longer but can also be rebuilt more times than any other makes.

These rollers resist wear to prevent premature wear of other undercarriage components. They extend the life of your crawler undercarriage.



Carrier Rollers.

Carrier Rollers are also lifetime lubricated using Metal Faced full floating seals. Large shafts and bearings carry load, while wear surface hardness & hardened depths are matched with links for a balanced wearing system. Carrier Rollers are cantilever mounted with large shafts and bearings.

Track Shoes.

Track shoes made from special deep-hardening alloy steels have a specially rolled design. They also have high core strength. Optimum leading and trailing radii keeps the shoes from cracking or bending and hardware from loosening.

Track shoes in wide range of sizes are available to suit the requirement of your crawler machine in variety of applications



Sprocket Rims & Segments.

TENGL sprocket rims and segments are designed to suit crawler operation in different applications.

Sprocket segments are easily replaced without any special tooling. Segments eliminate the risk of Rim misalignment. Thus, reducing maintenance and downtime expense. These segments simplify field replacements and result in worthwhile cost reduction.

Idlers:

Wide variety of constructional features built in for optimum performance in different end applications. The forged idlers are inherently stronger than the cast ones for a given weight. Induction hardened case depth on top of toughened body makes it long lasting.

Track Tension And Recoil Assembly (TTRA):

Heavy duty design to protect LA. and Idler from shock loads. Spring type design available for all sizes of undercarriage. For big size undercarriage, option of gas filled recoil mechanism is also available. Track tensioning is always by use of grease filled hyd. cylinder.



Crawler lowers …optimum efficiency for greater production.

TENGL puts the best part together to give you a complete picture of undercarriage efficiency. Tracks work together as a system to meet heavy duty demands in different applications.
