Overview
The CAT 320 and SDLG LG6210E sit in the same medium crawler class, separated by 1.0 tonnes of operating weight. They sit in different brand tiers (Caterpillar in premium, SDLG in value), which is the single biggest factor in how they'll behave over a 5-year ownership cycle.
Caterpillar 320 buyers across our Caribbean and African service area typically choose it for mid-class construction, road building, and quarry operations. SDLG LG6210E buyers, by contrast, tend to prioritise 21-tonne sdlg standard mid-class. The two machines have meaningful overlap on general construction-sector work, so a buyer with that application profile genuinely has a choice to make — and it's worth understanding the trade-offs in depth before committing.
Brand positioning
Caterpillar positioning
Caterpillar is the global benchmark — strongest parts logistics across our Caribbean and African service area, highest resale value retention, and the safest single-machine purchase decision for buyers prioritising uptime over upfront price.
SDLG positioning
SDLG is Volvo Construction Equipment's value-oriented brand. Volvo Group quality oversight at entry-level pricing.
What the tier difference means in practice
A premium-tier machine vs a value-tier machine typically differs across four dimensions over a 5-year ownership cycle: upfront capex (premium ~25-40% higher than value), fuel efficiency (premium ~5-10% better), parts availability (premium consistently 1-3 weeks faster on major components), and resale-value retention at year five (premium ~15-25 percentage points higher). On total cost of ownership the gap is typically much smaller than the upfront spread suggests — but cash-flow profiles differ significantly.
5-year total cost of ownership
Across a 5-year ownership cycle at typical African construction-sector use (2,000 operating hours/year, $1.20/L diesel, financed 50%), the CAT 320 typically delivers a total 5-year operating cost of $580-650k including acquisition, fuel, parts, service, financing interest, and resale recovery. The SDLG LG6210E comes in at $420-490k.
Acquisition (financed): Caterpillar 320 ~$160-220k, SDLG LG6210E ~$95-145k. That premium gap of 25-40% on day one is the largest single line item driving short-term cash-flow differences.
Fuel over 5 years: Both machines burn 20-30 L/h on standard duty. Across 10,000 lifetime operating hours that's $240-360k of diesel. Real-world consumption is close — within 5% variance.
Parts + service: Premium-tier parts run ~$14-18k/year for the CAT 320. Value-tier parts run ~$8.5-12.5k/year for the SDLG LG6210E.
Resale at year 5: Caterpillar typically holds 45-55% of acquisition price after 5 years. SDLG holds 25-35%. The resale gap is often the largest single TCO swing factor — premium-tier machines effectively rebate 15-25% more capital at year five.
Parts logistics & service support
Caterpillar parts logistics for CAT 320
Tractafric (Ghana, Cameroon), Mantrac (Tanzania, Kenya, Egypt, Nigeria), Bia (West Africa), Empresa Cubana de Maquinaria across the Caribbean — easily the strongest dealer network of any brand. Fast-moving wearing parts typically available within 24-72 hours; major components 1-3 weeks.
SDLG parts logistics for SDLG LG6210E
Dealer network across most major Caribbean and African markets. Fast-moving parts 5-10 days; major components 3-6 weeks via dealer network.
What this means in practice
Mining and infrastructure operations across Caribbean and African markets typically lose $2-5k per hour of unscheduled downtime — meaning a single 24-hour parts delay can cost more than the parts themselves. Choose the brand with the strongest parts logistics in your destination country and operating sector.
Configurations available
CAT 320 configurations available
- 320 (standard) — Standard configuration for general excavation and construction
- 320 GC — Cost-optimised newer-generation variant for mid-tier contractors
SDLG LG6210E configurations available
- LG6210E (standard) — Standard production configuration
Configuration choice (undercarriage track pattern, bucket capacity, hydraulic-circuit options, cab certification) drives 30%+ of total cost of ownership over a 5-year cycle. Whichever model you choose, specify configuration to the buyer's actual operating profile before order — retrofitting later costs 30-50% more.
