33ton R350lvs Hydraulic Crawler Excavator with 6 Cylinder Turbocharging Engine
1,Environmentally friendly, more powerful, faster and lower fuel consumption.
- The new Tier3 engine adopts advanced "diesel high pressure common rail electronic control injection technology".
- The diesel fuel combustion is full and thorough, which greatly improves the performance.
- Multi-fuel filtration system ensures engine durability and reduces harmful gas emissions, more environmentally friendly.
- Optimised oil circuit design of the main control valve improves the working speed and compound working ability.
- Higher loading efficiency and higher hourly capacity.
- Lower operation cost and higher return rate
2,IPC main pump intelligent control system VPC variable power control system
- IPC system intelligently controls the flow rate of the main pump through the operating handle, thus saving fuel consumption.
- The VPC system provides variable control of the pilot pressure to ensure that the operating speed and fuel performance are coordinated and matched in all operating modes, thus ensuring high efficiency and low consumption.
3,Longer durability of structural parts
- Installation of heavy-duty big and small arms with better durability, and use of cast steel products to improve strength and increase durability life by 1.5 times.
- The travelling and rotating motors are designed in-house by Hyundai Heavy Industries to enhance durability.
- Thickness of lower support ring increased and welding strength of lower frame increased by 20%.
4. Higher cooling performance - Adoption of large-capacity, high-efficiency cooling inline fan.
-The sealing sponge of cooling module is made of polyurethane sponge with higher oil and heat resistance.
5,Durable axle, sleeve and resin spacer. - Increase the lubricity of shaft and sleeve, improve wear resistance, and extend the grease injection cycle.
- Resin gaskets are applied to increase side lubrication and prevent wear and rattling.
- Minimize loosening of operating devices
6. Enhancement of electrical system performance
- Adoption of silicone sealing for MCU prevents moisture injection and resists vibration.
- Increased generator capacity and enhanced corrosion protection
- Enhanced durability and reliability of pressure sensor
7. Durable fuel tank
- Adoption of the plate and support type has increased the fatigue life of the welded part by 3.6 times (35% reduction in relative stress).
- Fuel filler port size increased (ø83 → ø104) to improve convenience and prevent overflow during filling.
