Introduction
The Terex TS-14 Double Bowl Scraper stands as a testament to mid-20th-century engineering ingenuity. Originally developed by Euclid and later enhanced by Terex, this machine revolutionized earthmoving operations with its dual-bowl design and robust performance. Its legacy endures, with some units still operational today, a nod to their enduring design and utility.
Historical Context and Development
In the late 1950s, Euclid recognized a growing demand for more efficient earthmoving equipment. The result was the TS-14, introduced in 1960. The machine featured two Detroit Diesel 4-71 engines, each delivering 136 horsepower, coupled with Allison CLT 3340 four-speed powershift transmissions. This configuration allowed for a top speed of approximately 25 mph, though operators often found that the machine's design prioritized durability and load capacity over speed.
The TS-14's simplicity was one of its key strengths. It was ruggedly built, easy to maintain, and parts were interchangeable with other Euclid scrapers. This made it particularly appealing to contractors who valued reliability and ease of service.

Innovations and Variants
The TS-14's design was not static; it evolved to meet changing demands and technological advancements. In 1963, Euclid introduced the Tandem TS-14, a dual-bowl configuration that allowed for increased capacity and efficiency. This model featured a 7UOT single-axle prime mover with two scrapers yoked together, each powered by a Detroit 4-71 engine. The combined system could achieve a total payload of 94,000 lbs and was particularly useful in expansive projects like canal construction.
Despite its impressive capabilities, the Tandem TS-14 was not without its challenges. The complexity of managing a 135-foot-long machine with multiple pivot points and powered axles required skilled operators and careful coordination. Nonetheless, it represented a significant leap forward in scraper technology.
Legacy and Continued Use
Even decades after its introduction, the TS-14 continues to be a subject of interest among heavy equipment enthusiasts and collectors. Its robust construction and historical significance have cemented its place in the annals of construction machinery. For instance, a rare Euclid/Terex scraper model was spotted in Missouri, still in operation, highlighting the enduring legacy of the TS-14.
Challenges and Maintenance Insights
Operating the TS-14, especially in its Tandem configuration, presented unique challenges. One notable issue was the air-controlled throttles of the rear engines, which could become unresponsive, leading to operational difficulties. Additionally, the center axle housing was prone to breakage under certain conditions. Operators often had to borrow alignment jigs from Euclid dealers to perform repairs.
Regular maintenance was crucial to keep these machines operational. The rear Detroit Diesel 4-71 engines, while powerful, required frequent overhauls to maintain performance. The harsh operating environments, such as sandy terrains, also contributed to wear and tear, necessitating diligent upkeep.
Conclusion
The Terex TS-14 Double Bowl Scraper is more than just a piece of machinery; it is a symbol of innovation and resilience in the field of earthmoving. Its design and capabilities set standards for future equipment and left an indelible mark on the industry. As we look back on its history, the TS-14 serves as a reminder of the ingenuity that drives progress in construction technology.
