The Terex TS14 and TS18 are legendary names in the world of earthmoving and heavy machinery, particularly for their dual-engine design. Designed for tough construction and mining tasks, these machines represent a leap in both engineering and performance for their time. This article explores the history, mechanics, and performance of these twin-engine scrapers, highlighting how they revolutionized the industry and the operators' experiences.
History of the Terex TS14 and TS18
Terex, a major American manufacturer of heavy equipment, became renowned for producing durable and reliable machines used in a variety of construction and mining applications. The Terex TS14 and TS18, introduced in the mid-20th century, were the company’s flagship twin-engine scrapers that drew attention for their innovative design and superior power.
The TS14, introduced in the 1960s, was designed to handle large-scale earth-moving projects, such as in road construction, land reclamation, and mining. With a focus on performance and reliability, it became a common sight at major construction sites and was particularly appreciated for its ability to move large quantities of material efficiently.
The TS18, introduced as an upgrade to the TS14, was a more powerful version, offering an increased engine capacity and improved operational features. Both machines featured a unique twin-engine design, where one engine powered the scraper’s traction system, while the other engine powered the bowl mechanism, allowing for more efficient material handling.
The Twin-Engine Design
The key feature that distinguished the Terex TS14 and TS18 from many other scrapers was their dual-engine configuration. Typically, heavy equipment utilizes a single engine for both movement and the operation of its working components. However, Terex’s design split these tasks between two engines, optimizing each engine's performance.
Operational Benefits
The twin-engine design came with several operational advantages, which made the Terex TS14 and TS18 highly sought after by operators in the field:
While the dual-engine design offered many advantages, it also presented challenges for operators and maintenance crews. Operating a twin-engine machine required a certain level of skill and knowledge:
Though production of the TS14 and TS18 ceased decades ago, their legacy lives on in the world of heavy equipment. These machines were some of the first to implement a dual-engine system, a design that would go on to influence future innovations in earthmoving and mining equipment.
Today, operators of older Terex models still appreciate the rugged performance these machines provided. Despite newer and more advanced models entering the market, many operators and businesses remember the TS14 and TS18 as workhorses that got the job done in some of the toughest conditions.
Terex’s focus on providing power, efficiency, and durability has influenced several manufacturers who have followed suit in developing similar systems in their equipment lines. While today’s machines may not rely on two engines, the principles of optimized power and performance remain central to the design of modern scrapers and other heavy-duty earthmoving machinery.
Conclusion
The Terex TS14 and TS18 were revolutionary in their time, offering unmatched power, efficiency, and durability thanks to their twin-engine design. While they came with their own set of challenges, such as increased maintenance and fuel consumption, these scrapers set the standard for heavy-duty machinery that could handle the toughest earthmoving jobs. Their legacy continues to influence the development of modern equipment, cementing their place in the history of heavy machinery. For those lucky enough to operate these machines during their prime, the Terex TS14 and TS18 were symbols of power, precision, and reliability.

The Twin-Engine Design
The key feature that distinguished the Terex TS14 and TS18 from many other scrapers was their dual-engine configuration. Typically, heavy equipment utilizes a single engine for both movement and the operation of its working components. However, Terex’s design split these tasks between two engines, optimizing each engine's performance.
- Traction Engine: The traction engine powers the scraper’s wheels and provides the machine's forward and backward motion. This engine is responsible for the machine’s mobility across the job site, driving the machine at considerable speeds while also managing the weight and stress of the scraper’s heavy loads.
- Bowl Engine: The second engine drives the scraper's bowl mechanism, which includes the loading, hauling, and unloading functions. The bowl engine provides the power to raise, lower, and dump the material in the scraper’s bowl, improving efficiency in material handling.
Operational Benefits
The twin-engine design came with several operational advantages, which made the Terex TS14 and TS18 highly sought after by operators in the field:
- Increased Efficiency: With one engine dedicated solely to movement and the other to the bowl, these machines could operate more smoothly and efficiently than single-engine models. This separation allowed for optimal power distribution and reduced the load on any single component, minimizing the risk of failure and downtime.
- Enhanced Power and Capacity: The combined power of two engines allowed these scrapers to move and manage larger loads of earth. The TS18, for example, was capable of handling even more material than the TS14, making it suitable for the largest construction and mining jobs.
- Improved Maneuverability: The ability to operate the two engines independently meant that the operator had more control over the machine. This was especially beneficial when working in tight spaces or when precise movement was required.
- Longevity and Durability: The design of these scrapers focused on durability. With two engines working in tandem, wear and tear were minimized. The components were built to last, and the machines often ran for years with minimal issues if maintained properly.
While the dual-engine design offered many advantages, it also presented challenges for operators and maintenance crews. Operating a twin-engine machine required a certain level of skill and knowledge:
- Complex Maintenance: With two engines to maintain, the Terex TS14 and TS18 required more intensive maintenance than single-engine models. Operators and mechanics had to be familiar with the intricacies of both engines, from their individual fuel systems to their electrical components.
- Fuel Efficiency: Operating two engines meant that fuel consumption was higher than that of single-engine machines. Operators had to balance power with fuel costs, particularly on long-haul projects, where fuel usage could significantly impact operational budgets.
- Mechanical Failure: While the dual-engine setup minimized wear on individual components, when something did fail, it could be more challenging and expensive to repair. The system of managing two engines required precision, and any failure in one engine could affect the performance of the entire system.
- Operator Training: The unique setup of these machines meant that operators needed specific training to operate them efficiently. They had to understand how to maximize the efficiency of each engine and learn how to address issues that arose from operating a dual-engine system.
Though production of the TS14 and TS18 ceased decades ago, their legacy lives on in the world of heavy equipment. These machines were some of the first to implement a dual-engine system, a design that would go on to influence future innovations in earthmoving and mining equipment.
