Do you trust new, non-traditional repair technologies to safely extend the life of your heavy equipment?
Vitalii Shevchuk of Chicago Endurance Welding LLC has developed a mobile hydraulic press designed to restore heavy-duty truck frame geometry. The system uses cold-pressing technology to realign steel without the structural risks associated with heat application.
Why it matters
Traditional welding and heat-based repairs can compromise the properties of heat-treated steel, potentially weakening the frame. By using cold straightening, technicians can restore structural integrity while maintaining the original strength of the vehicle components.
The repair process utilizes a 30-ton hydraulic cylinder to achieve precision, demonstrated by reducing lateral frame rail deviation from 32 mm to 2 mm. Vitalii Shevchuk applies these techniques based on over 20 years of experience in heavy equipment repair.

Vitalii Shevchuk
He is an experienced professional in infrastructure and heavy equipment repair with over 20 years in the field.
Chicago Endurance Welding LLC
This is an Illinois-based business that provides mobile repair services for heavy-duty truck frames.
The details
The mobile system integrates a 30-ton cylinder, a Mo-Clamp Tram Gauge, and a DeWalt laser level to assess and correct deformation. By identifying specific force application points, the process restores frame geometry through pressure rather than thermal stress.
Timeline
In April 2026, a Freightliner Cascadia truck frame was repaired using the system.
In September 2026, cold straightening was performed on a load-bearing frame using a custom reaction fixture.
Vitalii Shevchuk plans to formalize his methodology through documentation over the next 12 months.
Roadmap
This innovation represents a shift away from traditional thermal-based repair methods that have long defined the heavy equipment industry. By moving toward cold-pressing, the industry may eventually reduce dependency on heat-treating facilities for structural maintenance.
Fleet operators and truck owners can utilize these mobile services to repair frames without transporting heavy vehicles to distant specialized facilities. This could lead to reduced downtime and lower costs associated with structural repair services in the Chicago area.
The takeaway
Cold-pressing techniques offer a precise way to manage structural repairs without compromising the integrity of modern truck frames. Operators should consider verifying that repair providers utilize non-thermal methods to protect the long-term strength of their vehicle chassis.
