Home » Products » Excavators » Medium Hydraulic Excavator » 330E Hydraulic Crawler Excavator

330E hydraulic excavator is a newly developed E series excavator. The newly designed hydraulic system, with functions of flow collecting and regenerating, is used to help the engine perform better. Optimal match of the engine power and the hydraulic power helps improve working speed and thus increase working efficiency. The Cummins engine compliant with Tier 2 emission standard is utilized to offer high efficiency, environmental protection and fuel saving. Reinforced parts guarantee improved durability and reliability of the machine.

Cummins Turbocharged Engine (Original)
1. The Cummins turbocharged engine used for the crawler excavator provides world-class technology, powerful drive and low noise.
2. The total fuel consumption of the machine is evidently lower than other machines of its kind. The eco-friendly, energy saving excavator is designed to be compliant with Tier 2 emission standards.
3. The imported cyclone air cleaner helps prolong its lifetime and reduce the maintenance cost.

KAWASAKI Hydraulic System (Original)
1. The hydraulic pump comes with total power control, and the negative flow matches the power output from engine perfectly. This helps ensure high energy efficiency, and each flow changes proportionally.
2. The main valve has the functions of flow dividing, collecting, regenerating, straight travel, interlocking etc.
3. The revolving frame comes with wear-free hydraulic brake, and mechanical delayed locking ensures no impact and extended lifetime.

Japan NABTESCO Undercarriage Chassis
Intelligent dual-speed switchover guarantees smooth start and no impact. The normally-closed wet disc brake improves safety in grade braking.
