Key Features Across Doosan Propane Forklifts
Operator Sensing System (OSS)
Prevents truck movement when the operator is not properly seated. Locks hydraulic lifting and lowering and provides parking brake and seat belt warnings.
Guardian Stability System (GSS)
Available on 7-Series models, enhances safety and stability during cornering and lifting operations.
Oil-Cooled Disc Brakes
Standard on most models, providing exceptional durability, reduced maintenance, and reliable stopping power.
Powershift Transmission
Smooth, reliable power delivery for demanding applications. Available in 1-speed and 2-speed configurations.
Low-Emission LPG Engines
Doosan propane forklifts are equipped with LPG engines that produce significantly lower emissions than diesel, making them suitable for indoor use with proper ventilation.
High-Visibility Mast
Designed with narrow channels for improved forward visibility and safer load handling.
Hydrostatic Steering
Reduces operator fatigue and provides precise control in tight spaces.
Cushion or Pneumatic Tire Options
Cushion tires: Best for smooth indoor surfaces, offering tight turning radius and floor protection.
Pneumatic tires: Best for outdoor and uneven surfaces, providing superior traction and shock absorption.
Propane vs. Diesel – Why Choose LPG?

Noise Level Quieter Louder
Cold Weather Start Excellent Good
Maintenance Moderate Higher
Indoor Use Yes (with ventilation) No (except with extensive controls)
2026 Pricing Guide
Doosan propane forklift prices vary significantly based on model, capacity, configuration, and condition.
New Units
New Doosan propane forklifts are available through authorized dealers. Pricing depends on capacity, mast configuration, attachments, tire type, and regional factors. Contact a local Doosan or Bobcat dealer for accurate quotes.
Used Market
Used Doosan propane forklifts are available through equipment marketplaces such as Machinio, Machineryline, and auction platforms. Prices vary by age, hours, condition, and configuration.
Note: Prices vary by condition, hours, mast configuration, attachments, and location. Most used units are sold "as-is, where-is" with no warranty unless specified.
Buying Considerations
1. Match Capacity to Your Load
Doosan propane forklifts range from 1.5 to 5.0 tonnes. Choose a model with at least 20% capacity above your heaviest typical load.
2. Choose the Right Tire Type
Cushion tires: For indoor warehouse use on smooth concrete floors.
Pneumatic tires: For outdoor or mixed indoor/outdoor use on uneven surfaces.
3. Evaluate Your Operating Environment
Indoor warehouses: Propane forklifts are a popular choice for indoor use with proper ventilation.
Mixed indoor/outdoor: Propane forklifts offer the flexibility to operate both indoors and outdoors.
Outdoor only: Diesel may be more cost-effective for heavy outdoor use.
4. Check Mast Configuration
Standard masts offer 3.0 m lift height. Triplex masts are available for higher stacking. Verify the mast type matches your racking height requirements.
5. 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
6. 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.
7. Consider Total Cost of Ownership
Factor in fuel costs, maintenance intervals, parts availability, and expected service life—not just the purchase price.
