LiuGongProduct Description of LiuGong CLG906E Used Agricultural Excavator

I. Product Introduction

II. Main Features

(I) Maneuverability

• With a compact body design, it is extremely flexible in operation. It can easily move and work in narrow farmlands, orchards, or small construction sites. The control system of the excavator is precise, allowing operators to complete fine - grained excavation, soil - moving, and other operations.
• The crawler - type walking mechanism has good ground adaptability. Whether it is in the soft soil of farmlands or on uneven construction sites, it can walk and operate stably.

(II) Durability

• Key components such as the boom, stick, and bucket of the excavator are made of high - strength materials. After a period of use, although there are signs of wear on the appearance, the main structural components still have a relatively long service life under reasonable use and maintenance.
• The engine and hydraulic system are relatively reliable. LiuGong's mature manufacturing technology ensures that these core components can still maintain good performance after secondary use.

(III) Cost - effectiveness

• As a second - hand equipment, compared with new excavators, its purchase cost is relatively low, which can greatly reduce the investment cost for users. For small - scale agricultural operations or individual contractors, it is a very economical choice. At the same time, the subsequent maintenance cost is also relatively reasonable, and maintenance parts are relatively easy to obtain.

III. Application Scenarios

(I) Agricultural Field Operations

• Farmland Renovation: It can be used for operations such as farmland leveling, ditch digging, and ridge building. For example, in the process of transforming irregular farmlands into standardized plots suitable for large - scale mechanical operations, the LiuGong CLG906E can efficiently complete soil - moving and shaping operations.
• Orchard Construction and Maintenance: In orchards, it can be used for tasks such as digging tree - planting pits, building irrigation ditches, and cleaning up orchard waste. Its small size allows it to move flexibly among fruit trees without damaging the orchard environment.

(II) Small - scale Engineering Construction

• Village Road Construction: In rural road construction, it can be used for foundation excavation, side ditch digging, etc. For the construction of some small - scale rural roads, its size and performance can well meet the construction needs.
• Small - scale Building Construction: During the construction of rural houses or small - scale buildings, it can be used for foundation excavation, (if any) basement construction, and backfilling operations.

IV. Technical Specifications

V. Common Problems and Solutions

(I) Hydraulic System Failure

• Problem: The hydraulic system may have problems such as oil leakage and unstable pressure. Oil leakage may be due to aging of seals or loosening of pipe joints; unstable pressure may be caused by failures of the hydraulic pump or valve group. These problems will reduce the working efficiency of the excavator, and in severe cases, affect the normal operation of the equipment.
• Solution: Regularly check the hydraulic system for oil leakage. If oil leakage is found, replace the aging seals or tighten the pipe joints in a timely manner. For the problem of unstable pressure, first check the working status of the hydraulic pump. If necessary, clean or replace the filter element, check whether the valve group works normally, and repair or replace the faulty components.

(II) Difficult Engine Start or Insufficient Power

• Problem: Difficult starting may be due to insufficient battery power, starter failure, or fuel system blockage, etc.; insufficient power may be caused by factors such as air filter blockage, fuel quality problems, or engine component wear. These problems directly affect the working performance of the excavator and reduce construction efficiency.
• Solution: When starting is difficult, first check the battery power. If necessary, charge or replace the battery; check whether the starter is faulty and repair or replace it. For the fuel system, clean the fuel filter and check the fuel pipeline. When there is insufficient power, clean or replace the air filter in a timely manner, use high - quality fuel, check whether the engine components are worn, and repair or replace the worn parts.

(III) Track Wear and Deviation

• Problem: After long - term use, the crawler tracks will be worn, and there may also be a problem of track deviation. Track wear affects the walking stability of the excavator, and track deviation will cause uneven force on the equipment and affect the operation effect.
• Solution: Regularly check the wear condition of the tracks. When the wear reaches a certain level, replace the tracks in a timely manner. For the problem of track deviation, check the track tension and the working status of the track adjustment device, adjust the track tension to an appropriate range, and ensure the smooth operation of the tracks.

(IV) Electrical System Malfunction

• Problem: The electrical system may have problems such as fuse blowing, sensor failure, and abnormal instrument display. These problems will cause some electrical equipment of the excavator to fail, affecting the normal operation and operation monitoring of the equipment.
• Solution: Regularly check the electrical system, including fuses, sensors, and instruments. When a fuse is blown, replace it with a fuse of the corresponding specification; when a sensor fails, repair or replace the sensor; when the instrument display is abnormal, check the instrument circuit and the connection between the instrument and other components, and repair the faulty parts.
