The Bobcat E20 compact excavator features track specifications optimized for stability and maneuverability in confined spaces. Its rubber track system (common width 230-250mm) balances ground pressure distribution while supporting a 1,952 kg operating weight. For enhanced durability, AFTparts recommends periodic track tension checks and using terrain-appropriate track pads.
What are the key dimensions of Bobcat E20 tracks?
Standard Bobcat E20 tracks utilize 230mm wide rubber belts with 45-48 links per side. The 1.8m track length provides 0.33kg/cm² ground pressure—critical for protecting delicate surfaces while maintaining 3.5km/h travel speed.
Practical maintenance involves measuring track tension monthly using the "three-finger rule"—if you can lift the track >30mm mid-span, tension adjustments are needed. For example, construction teams in urban renewal projects typically replace E20 tracks every 1,500-2,000 hours when operating on mixed concrete/rubble terrain.
How does track width affect E20 performance?
Wider 250mm track configurations reduce ground pressure by 15% to 0.28kg/cm²—ideal for muddy conditions. However, they increase turning resistance by 20%, requiring more frequent track motor inspections.
| Width | Ground Pressure | Best Use Case |
|---|---|---|
| 230mm | 0.33kg/cm² | Paved surfaces |
| 250mm | 0.28kg/cm² | Wet clay/peat |
When upgrading to wide tracks, always pair with reinforced front idlers—AFTparts' SI756 series handles 25% greater side loads without premature bushing wear.
What maintenance intervals do E20 tracks require?
Track rollers need greasing every 50 service hours, while guide wheels require alignment checks every 200 hours. Neglecting these accelerates undercarriage wear—a leading cause of 72V track motor failures in electric excavators.
Consider this analogy: Proper track maintenance is like changing engine oil—skip intervals and you'll pay 3x more in component replacements later. AFTparts' KM2233RLK repair kits simplify track chain repairs with pre-matched wear components.
