CX50 Series

  • Tire type Pneumatic Pneumatic
  • Power type LPG/Dual fuel LPG/Dual fuel
  • Capacity 3 500 - 5 000 kg 8,000 - 11,000 lbs.

Fast, clean and powerful

Who would have thought moving 8,000- to 11,000-pound loads in high volume could be effortless? The CX50’s fusion of advanced engine technologies and a unique hydraulic system was engineered to deliver outstanding performance while reducing cost and Carbon Dioxide emissions, compared to previous models.

  • Designed for low costs of operation
  • Engineered for reliability in a variety of conditions
  • Helps operators work efficiently

Features and benefits

Hydraulics that do more than lift

To minimize hydraulic loss and reduce the engine load, the CX50 Series uses the CLSS hydraulic system, technology proven in Komatsu’s rugged construction machines. Reducing the engine’s load means it uses less fuel than typical gear pump-driven hydraulic trucks.

Brakes built for a variety of conditions

Smooth, stable braking and fade resistance in a variety of conditions. Unlike conventional drum and shoe braking systems, the CX50 Series features a wet disc brake system sealed with oil to block dust and water-resistant components.

Robust hydraulic and electrical systems

Separate hydraulic and electrical systems improve reliability and service accessibility. O-ring face seals on critical hydraulic connections reduce the potential for leaks. Water- and dust-resistant connectors join the main harnesses and the system controller.

Advanced Ergonomic Design

Designed to improve operator comfort and reduce fatigue, the Komatsu Komfort Zone is a dual floating structure: dampening mounts protect the frame from engine vibration; additional mounts isolate operators from the frame; and the sealed floorboard reduces engine noise and heat.
