Manufacturing Process

Step-by-Step Engineering Workflow

1. Steel Cutting: CNC laser/plasma cutting for structural components.

2. Welding: Robotic MIG welding ensures stable joints and fatigue resistance.

3. Heat Treatment: Stress-relief processing of boom/arm assemblies.

4. Machining: Precision boring and milling of hinge points and bearing seats.

5. Painting: Shot blasting + epoxy primer + polyurethane topcoat.

6. Hydraulic Installation: Pump, valves, cylinders, and hoses assembled with pressure testing.

7. Electrical System: Wiring harness installation and function calibration.

8. Final Assembly: Track frame, upper structure, counterweight, canopy.

9. Testing: Load test, travel test, hydraulic leakage test, noise/vibration inspection.

Key Production Equipment

• Robotic welding stations

• CNC machining centers

• Hydraulic pressure testing benches

• Paint booth with automated drying line

• Endurance-test platforms

Critical Quality Control Points

• Hydraulic cylinder sealing and pressure retention

• Weld penetration depth ≥ 85%

• Boom/arm geometric alignment (tolerance ±0.5 mm)

• Track tension and rolling resistance testing

• Engine emission compliance verification

Industry Comparison

Application Scenarios

• Landscaping and garden maintenance

• Urban infrastructure foundation trenching

• Pipeline installation and cable laying

• Indoor demolition and confined-space operations

• Agricultural land preparation and orchard maintenance

• Municipal repair and drainage works

• Small-scale construction and real estate projects

Core Pain Points & Engineering Solutions

• Limited engine torque in small machines: Upgraded hydraulic pump and optimized valve matching improve digging efficiency.

• Track wear in urban surfaces: Reinforced rubber track formula increases lifespan by 15–25%.

• Overheating during long operations: Enhanced cooling module with larger core and optimized airflow.

• Hydraulic leakage risks: High-pressure hose routing design and sealed connectors prevent early failure.

• Operator fatigue: Pilot-assisted joysticks and suspended seat reduce vibration exposure.

Risk Warnings & Mitigation Suggestions

• Avoid overloading the boom; exceeding rated digging force may cause structural fatigue.

• Perform daily grease lubrication for hinge points to prevent premature wear.

• Operate only on stable ground; small machines have limited counterweight balance.

• Use correct hydraulic attachments; mismatched flow can damage seals and valves.

• Store indoors to avoid long-term UV exposure on rubber components.

Procurement and Selection Guide

1. Define expected digging depth and operating radius.

2. Check engine brand, emission compliance, and fuel consumption rate.

3. Evaluate hydraulic system capacity (pump flow, pressure, valve type).

4. Compare boom/arm structure thickness and welding quality.

5. Inspect track frame quality, roller strength, and ground clearance.

6. Confirm auxiliary hydraulic line specifications for attachments.

7. Review test reports and QC records provided by the manufacturer.

8. Assess spare parts availability and after-sales support.

Engineering Case Study

Urban Residential Foundation Project – Europe (2024)
A contractor used ten 1.2 ton excavators for narrow-area trenching in a residential district. With a 1,850 mm digging depth and compact 980 mm width, the machines reduced excavation time by 32% compared to larger units. Fuel consumption decreased by 18%, and transport logistics were simplified, enabling rapid multi-site deployment.
