Buying Considerations
1. Match Capacity to Your Load
Doosan diesel forklifts range from 1.5 to 25.0 tonnes. Choose a model with at least 20% capacity above your heaviest typical load.
2. Evaluate Your Operating Environment
Outdoor / Rough Terrain: Diesel is the preferred choice for its power, torque, and durability.
Mixed Indoor/Outdoor: Consider LPG models for lower emissions.
Indoor Only: Electric models offer zero emissions and lower operating costs.
3. Check Emissions Compliance
Ensure the model meets local emission regulations (e.g., EPA Tier 4, EU Stage V).
4. Inspect Used Units Thoroughly
Most used units are sold "as-is, where-is." Check:
Hour meter reading
Engine condition and maintenance records
Mast wear and hydraulic system
Tire condition
Transmission and brake performance
5. Verify Parts Availability
Doosan forklift parts are available through Doosan and Bobcat dealer networks. Aftermarket parts are also available through TVH, Intella Parts, and other suppliers.
6. Consider Total Cost of Ownership
Factor in fuel consumption, maintenance intervals, parts availability, and expected service life—not just the purchase price.
