Terramac Introduces the New RT15R Rotating Crawler Carrier
CK Power Family of Companies is excited to share that our Terramac division launched its RT15R rotating crawler carrier, the next evolution of its rotating product line.
Replacing the highly successful RT14R, the RT15R builds upon a proven platform while incorporating significant customer-driven enhancements designed to improve performance, safety, operator comfort, serviceability, and overall productivity. The RT15R joins Terramac’s RT7R to enhance the company’s rotating crawler carrier lineup and provide contractors with a versatile solution for demanding jobsite applications.

Developed through direct customer feedback and real-world application insights, the RT15R delivers greater capability with a one-ton increase in payload while introducing a host of refinements that make the machine more productive throughout the workday. An all-new Stage V Cummins B6.7 engine paired with extensive hydraulic and cooling system improvements delivers quieter operation, improved fuel efficiency, and smoother performance. Enhanced service access, simplified maintenance points, and upgraded diagnostics help reduce downtime and improve long-term reliability.
Operators will also benefit from a redesigned cab featuring improved climate control, a larger touchscreen display, enhanced visibility, and added convenience features that create a more comfortable working environment. New safety enhancements, including improved access steps, electronic operator alerts, integrated bed safety features, and a standard fire extinguisher, further reinforce the RT15R’s focus on protecting operators in the field.
Together, these advancements build on the proven versatility of Terramac’s 360-degree rotating platform, delivering a machine that is more capable, more efficient, and easier to own and operate.
The introduction of the RT15R reflects Terramac’s ongoing commitment to developing equipment that meets evolving customer needs while maintaining the durability and performance contractors expect in the field.
First Units Built and Delivered from St. Louis Facility
Adding to the excitement surrounding the RT15R launch, the first three production units were successfully built at Terramac’s St. Louis manufacturing facility and delivered to jobsites this quarter.
This milestone marks the successful transition of the RT15R from development and testing into full-scale production and field deployment.
“This RT15R reflects what is possible when our engineering, manufacturing, quality, procurement, and sales teams are aligned around a defined customer requirement and execute with discipline and speed,” said JJ Costello, Co-CEO of the CK Power Family of Companies. “I am extremely proud of the Terramac team for bringing this product to market and delivering it to the customer. It is a strong example of how we operate to solve real challenges and deliver reliable solutions for our customers.”
The successful launch and delivery of the first RT15R units highlights the coordinated effort required across engineering, manufacturing, supply chain, quality, and sales teams to bring a new product from concept to customer.
Building on a Proven Foundation
The RT15R represents Terramac and the CK Power Family of Companies continued investment in product innovation and customer-focused equipment development. By enhancing a platform already trusted by contractors across multiple industries, Terramac has delivered a next-generation rotating crawler carrier that offers greater capability, lower operating costs, and an improved ownership experience while preserving the versatility and performance that made the RT14R a customer favorite.
As RT15R production ramps up, Terramac remains focused on providing purpose-built equipment solutions that help customers work safer, more efficiently, and more productively in challenging environments.
