Prinoth’s T23r is equipped with the new PowerForce undercarriage that’s engineered for maximum terrain performance
With its new flagship Panther T23r, the industry’s largest rotating crawler carrier, Prinoth is introducing a patent-heavy undercarriage system engineered to deliver higher payloads, smoother operation and improved performance in challenging terrain conditions.
The Panther T23r is the first machine to feature Prinoth’s PowerForce undercarriage, a new design underpinning more than 20 patent applications, delivering impressive terrain performance and operational efficiency.
“The engineers at Prinoth have worked really hard over the past couple years to develop the perfect machine,” said CEO Marc Lepage. “We wanted to have high productivity. We wanted it to be top quality, minimize downtime, and we wanted it to be absolutely comfortable for your operators. And I think that they nailed it for this.”
The Panther T23r carries the largest payload at 22.5 tons while maintaining a 3-metre width, 3.175 metre height and a 40-ton operating weight.
Its continuous 360-degree rotating upper structure and rounded Hardox steel dump box with telescopic cylinder enable precise material placement in confined spaces.
PowerForce undercarriage
The PowerForce undercarriage represents a fundamental advancement in crawler carrier design. Rather than a walking beam system that transfers vibration, PowerForce absorbs terrain variations while maximizing power transfer to the ground. The result is a machine that travels faster, saves fuel and improves operator comfort.
“Customers are pushing farther into remote, sensitive and high-consequence environments,” said Frank M. Gangi, Product Manager for the Prinoth Panther. “With the Panther T23r, we set out to give them a machine that feels completely in control on those sites, with a payload and undercarriage that lets them haul more in fewer passes while protecting the jobsite and the machine.”
The PowerForce undercarriage positions eight wheels on independent arms, each providing 18-cm of travel through hydro-pneumatic shock absorbers that automatically adjust to load conditions, absorbing terrain impacts and protecting the operator.

This dual-setting system maintains consistent ride quality whether the machine is empty at 18,700 kg or fully loaded at 38,750 kg. Strategic weight distribution places 60 per cent of the load on centre wheels, improving zero-turn capability and reducing ground pressure.
As well, Prinoth engineers developed an oval track shape that reduces bend points by 50 per cent and doubles the bend radius compared to conventional designs. This geometry minimizes energy loss at each track revolution, transferring more engine power directly to vehicle motion. The design also increases ground contact area for improved flotation in soft conditions and enhanced traction on slopes.
The PowerForce system achieves track pitch precision 10 times greater than standard carriers, according to Prinoth.
Engineered with precise link spacing, with an auto-centering fox head profile, the planetary drives deliver smooth sprocket operation, engaging 15 teeth simultaneously instead of a conventional single-point contact. Its roller and wheel configuration virtually eliminates de-tracking, even under extreme manoeuvring, minimizing downtime and extending track life.
A dual-action automatic tensioning system continuously optimizes track tension based on operating conditions. The system reduces tension when the machine is lightly loaded to minimize component wear, then increases tension automatically when additional traction is required.
The real-time track adjustment extends undercarriage service life while ensuring maximum performance across all terrain types.
Advanced dump box design
The rounded shape of the Hardox steel deep-section box promotes smooth material flow and reduces carryback, especially with sticky soils and aggregates.
Prinoth moved the dump box closer to the undercarriage centreline compared with traditional designs, optimizing its centre of gravity and balancing loads across the suspension and central bearing, which helps reduce stress, weight and complexity in the frame.
The Panther T23r also features Prinoth’s new cab with a near centre-mounted operator position that provides enhanced visibility to the right side where ground personnel typically work. Standard equipment includes an air-ride seat, 18-cm touchscreen display, ergonomic joystick controls, for dump and rotate, intuitive steering wheel and foot throttle drive system, sun visor and cruise control for reduced operator fatigue during long shifts. An optional buddy seat is also available.
