In scenarios such as interior decoration, home renovations, agricultural cultivation, and municipal micro-projects, the GC-E08 to GC-E25 compact excavators have become the core equipment for customers tackling ‘difficult small jobs’ due to their flexibility, efficiency, and ease of operation. However, with multiple models available—including the GC-E08, GC-E10, GC-E12, GC-E15, GC-E18 (standard/tail-less versions), GC-E20, and GC-E25—how does one precisely match operational requirements? This guide combines the core strengths of the entire series, approaching selection through a four-dimensional lens: ‘Application Scenario - Model - Specifications - Configuration’—to provide you with a bespoke purchasing guide.
Step One: Select the model according to the scenario; each model has its own dedicated compatible scenario.
The GC-E08 to GC-E25 models encompass eight distinct variants, each engineered to address specific operational challenges, thereby avoiding the pitfalls of oversizing or undersizing:
Ultra-narrow space operations: GC-E08, GC-E10, GC-E12 — millimetre-level precision manoeuvring
GC-E08: Indoor / Ultra-Narrow Scenarios ‘Door-Passing Wonder’
Suitable Scenarios: Interior renovation demolition (e.g., stripping old walls, floor removal), basement pipe excavation (water pipes/cable trenches ≤30cm diameter), nursery plant transplanting (single root ball diameter ≤50cm).
GC-E10/GC-E12: Precision Operation ‘Upgraded Models’
Suitable Scenarios: Small pet shops / commercial premises renovations (e.g., foundation excavation for partition walls), complex terrain management in domestic gardens (e.g., excavation for rockery bases, small pond construction), small fertiliser trench digging in orchards (depth ≤60cm).
Small to medium-sized multi-purpose operations: GC-E15, GC-E18 (Standard model / Tail-less model) — Combining flexibility with efficiency
GC-E15: The “Jack-of-All-Trades” for Small to Medium-Sized Applications
Suitable Applications:
- Tilling in vegetable greenhouses (width ≤ 8 metres)
- Rural path repairs (3-metre-wide surface levelling)
- Tree planting in residential green spaces (digging pits for trees with trunk diameters ≤ 15cm)
GC-E18: Compact Engineering ‘Efficiency Edition’
Suitable Applications: Township-level municipal repairs (e.g., pavement tile refurbishment, small drainage well excavation), medium-sized orchard irrigation trench digging (depth ≤1.2 metres), small construction site foundation breaking (concrete thickness ≤10cm).
GC-E18T: The Ultimate Space-Saver for Tight Spaces
Suitable Applications: Renovation of stairwells in older residential buildings (operating within stairwells ≤2 metres wide), deep excavation indoors (e.g., breaking basement wall foundations), and demolition of equipment foundations in factory buildings (where surrounding obstacles exist).
Medium-to-large-scale operations: GC-E20, GC-E25 tonnes — Exceptional power and stability
GC-E20: Medium-Duty ‘High-Efficiency Workhorse’
Suitable Applications: Small-scale farmland improvement (e.g., irrigation channel construction, width ≤1.5 metres), residential car park foundation excavation (depth ≤1.5 metres), municipal small-diameter pipeline laying (trench for pipes ≤50cm diameter).
GC-E25 Ton: Medium-to-Large-Scale Operations ‘Bridge Model’
Suitable Applications: Construction of small-scale township parks (e.g., foundation excavation for landscape lakes, footpath laying), medium-scale farmland levelling (plots ≤5 mu), auxiliary excavation for small bridge foundations (excavation depth ≤1.8 metres).
Step Two: Keep a close eye on three key parameters to avoid making the wrong choice.
After selecting the appropriate model, attention must be paid to key parameters that align with operational requirements. The following three categories of parameters directly impact performance:
1. Excavator digging force and attachment compatibility: Select according to material type.
Loose soil, planting soil: Select models with 10-13kN digging force, fitted with standard earthmoving buckets;
Clay, gravel: Select models with 15-18kN digging force, fitted with pointed-tooth buckets;
Concrete breaking, hard soil: Select models with 18-20kN digging force, compatible with hydraulic breakers;
Precision trenching for pipelines: Select models with bucket width ≤50cm, fitted with narrow buckets.
Note: All our models support customised attachments, accommodating log grapples, rippers, etc. as required.
2. Dimensions and Passability: Select by Space
Indoor / Stairwell Operations: Select models with a body width ≤1.1 metres and a turning radius ≤1.8 metres;
Field / Muddy Terrain: Select models with a track width ≥350mm and minimum ground clearance ≥160mm;
Transport Convenience: Select models with a transport height ≤2.3 metres.
Step Three: Focus on three categories of practical settings to enhance your working experience.
The right configuration can double your productivity. Below are the core configuration advantages of our driver-oriented model, which you may wish to prioritise when making your selection:
1. Operational configuration: Quick to master, even for novices
2. Safety and comfort features: Peace of mind during extended operations
3. After-sales service and warranty: Complete reassurance
Summary: Three steps to pinpoint the model that suits you
Scene selection: Initially filter models based on workspace (indoor/outdoor/extremely confined), material type (loose soil/hard soil/rubble), and daily operating duration.
Review specifications: Verify that digging force, machine dimensions, and power source align with requirements.
Select configuration: Choose based on operator proficiency and expected operating hours.
Review specifications: Verify that breakout force, machine dimensions, and power source align with operational requirements.
