Semi-Universal Blade

Semi-Universal (SU) blade

• SU blade combines the excellent penetration of the S blade and the high production capacity of the U blade.
• Designed for superior load retention and penetration in tightly packed materials.
• L-shaped push arms bring the blade closer to the machine, providing excellent maneuverability, balance and blade penetration.
• Blades feature a strong box section design, made from high tensile strength steel to stand up to the most severe applications.

Undercarriage

• Undercarriage is provided by a world class supplier ensures high reliability and resistance to wear.
• Carrier rollers track rollers and idle rollers areall maintenance free.
• Planetary final drive design delivers increased torque ratio for higher transmission efficiency and lower maintenance cost.
• Durable final drive bearings and multiple wet disc brakes provide reliability, reduce system heat and extend overall life.

 

Structures

• Machine structures are analyzed using Finite Element Analysis (FEA) and On Machine Stress Analysis (OMSA) toidentify and protect high stress areas.
• Advanced structure welding technique, relieving weldingstress.

 

Modular Radiator

• New advanced cooling system designed to meet -43°C to +50°C ambient temperatures capability.
• Modular designed radiator, easy to maintain remove and repair.
• Radiator grill provides better heat dissipation, easy access for maintenance.

 

Maintenance

• Electronic Control Module (ECM) fault diagnosis system, automatic diagnosis of eight key parameters.
• Monitoring system provides three levels of alarm, toindicate fault diagnosis.
• Hydrostatic system has longer service interval (2000 hrs), reduces maintenance time by 50%.
• Implement valve mounted outside of hydraulic tank provides easy access to check and service.
