Heritage and Evolution
Terex rigid dump trucks trace their lineage back to the pioneering days of off-road dump truck manufacturing beginning in 1934. The brand’s heritage includes significant milestones such as the acquisition and continuation of Euclid equipment designs, incorporation of General Motors’ engineering expertise, and sustained manufacture at the Motherwell facility in Scotland since 1950. This rich background laid the foundation for robust, high-performance rigid frame trucks designed for intensive applications in mining, quarrying, and heavy construction.
Design and Build
Terex rigid dump trucks offer a storied legacy of toughness and innovation in heavy haulage. The continuous product improvements, combined with strong manufacturing excellence in Scotland, have secured their role as dependable machines capable of handling the toughest hauling conditions globally. Today, the Terex brand represents a fusion of historic quality and modern advancement, supported by comprehensive service networks ensuring maximum equipment uptime.

Design and Build
- Terex rigid dump trucks are engineered with high-strength steel box beam frames and robust chassis built to withstand the rigorous demands of severe hauling environments including deserts and arctic conditions.
- Typically powered by reliable diesel engines from Cummins or Detroit Diesel, these trucks provide a balance of fuel efficiency and power suitable for loads ranging from approximately 25 to 40 metric tons or more.
- Transmission systems vary but often include multi-speed powershift gearboxes that ensure smooth torque delivery and operational productivity.
- Early Terex models such as the 2366 and 2566 were known for payload capacities of 23 to 25 metric tons. Subsequent increases introduced larger models like the 2766, 3066, and the substantial 4066, broadening the range up to 40-ton capacities.
- These models evolved into upgraded “C” series (e.g., 2566C, 2766C) with improved engine technology, emissions compliance, and electronic system enhancements to maintain competitiveness.
- In 1998, Terex rebranded their truck line with “TR” prefixes for rigid dumpers and “TA” for articulated trucks, coupled with capacity-based model numbering (e.g., TR35 for 35-ton rigid dump trucks). The company also transitioned to a distinctive white paint scheme with red and black accents, marking a departure from the earlier lime green classic look.
- Terex rigid dump trucks gained a reputation for their durability, ease of maintenance, and strong aftermarket support, making them favorites among operators in demanding environments worldwide.
- Terex’s articulated dump truck division was acquired by Volvo Construction Equipment in 2014, leading to the introduction of new models under the Rokbak nameplate with advanced features such as independent front suspension and emissions-compliant engines.
- While articulated dump trucks moved forward under Rokbak, Terex rigid dump trucks continue to be a core product line combining legacy robustness with modern technology.
- Rigid Dump Truck: A heavy-duty truck with a fixed chassis and dump bed typically used for hauling in mining and construction.
- Powershift Transmission: Gear system allowing seamless gear changes under load without manual clutching.
- Payload Capacity: The maximum weight a truck can safely carry in its dump body.
- Independent Front Suspension: Suspension system that allows each wheel on the front axle to move independently, improving traction and ride quality on rough terrain.
- Emission Compliance: Design features and technologies that meet environmental standards for exhaust gases.
