Product Description of ZOOMLION Hydraulic Excavator ZE385G

I. Product Introduction

II. Main Features

1. Powerful Performance: Equipped with a high - performance engine, with a rated power of 214kW. It has stable and sufficient output, and responds quickly to heavy - duty excavation and crushing operations, easily dealing with hard material working conditions.
2. High Efficiency and Energy Saving: Adopts an intelligent hydraulic control system, accurately matches power and load, optimizes flow distribution, reduces fuel consumption, and improves the energy efficiency ratio of operations.
3. Durable and Reliable: The reinforced boom, stick and undercarriage are made of high - strength wear - resistant steel. The key hinge points are equipped with high - precision seals, adapting to the harsh working conditions of mines and prolonging the service life of the equipment.
4. Intelligent Control: Integrates a digital instrument panel and control system, monitors the equipment status in real - time, with complete functions such as fault warning and fuel consumption statistics, and is convenient to operate and efficient to maintain.

III. Application Scenarios

• Mine Excavation: Suitable for open - pit mine rock stripping and ore loading, with stable and efficient heavy - duty crushing operations.
• Infrastructure Projects: For large - scale earth - rock excavation (such as road and railway subgrades) and water conservancy facilities (reservoir and river dredging) construction, meeting the needs of high - intensity operations.
• Port Logistics: For port bulk cargo loading and unloading and site leveling. With large bucket capacity and high mobility, it improves the efficiency of material transfer.

V. Common Problems

1. Over - high Oil Temperature of Hydraulic System
   • Causes: Blocked cooling system, hydraulic oil not replaced for a long time, continuous excessive load.
   • Solution: Clean the radiator, replace the qualified hydraulic oil according to the cycle, and reasonably arrange the operation load to avoid long - term heavy - duty pressure holding.
2. Track Deviation
   • Causes: Inconsistent track tension, flow difference of travel motors, jamming of single - side track shoes.
   • Solution: Adjust the pressure of the track tension cylinder, overhaul the hydraulic valve group of the travel motor, clean the track foreign matter and check the track frame.
3. Difficult Engine Start
   • Causes: Battery power loss, blocked fuel filter, starter motor failure.
   • Solution: Check the battery power and wiring, replace the fuel filter, overhaul or replace the starter motor.
4. Insufficient Digging Force
   • Causes: Abnormal main pump pressure, internal leakage of the control valve group, engine power attenuation.
   • Solution: Detect and adjust the main pump pressure, overhaul the seals of the control valve group, and check the engine oil circuit and fuel injection system.
