• Steel Structures – Mild steel used throughout frame provides flexibility, durability and resistance to impact loads, even in cold climates and allows for easy field repairs.
• Castings – Castings account for 80 percent of the frame’s weight and are key to providing durability in some of the world’s toughest conditions. The large radii castings are resilient to frame flexing and ensure long life.

Integral Four-Post Cab

Resiliently mounted to the frame to reduce vibration and sound, the integral ROPS is designed as an extension of the truck frame.

Suspension System

Designed to dissipate haul road and loading impacts for longer frame life and a more comfortable ride.

• Durable Design – Rugged cylinders utilize large diameter bore and low pressure nitrogen/oil design for long life with minimal maintenance.
• Front – Front cylinders with preset caster and camber are mounted on the frame and serve as steering kingpins for a tight turning radius with excellent maneuverability and low maintenance.
• Rear – Rear cylinders allow oscillation and absorb bending and twisting stresses caused by uneven and rough haul roads rather than transmitting them to the main frame.

Four-Bar Link Rear Suspension

The four-bar link suspension transfers and supports loads to the frame more efficiently than an A-frame design and allows more service area around the transmission.

Steering System

Hydraulic steering control system is designed for exceptional smoothness and precise control. A separate circuit prevents cross contamination for long life.
