Doosan Forklift – descended from Daewoo, a code of power source and generation, plus diesel versus LPG versus electric power by workplace
Doosan's counterbalance forklifts trace back to the former forklift division of Daewoo Heavy Industries, carried on under the Doosan name after the group's rebranding. The type code opens with a letter for the power source — "G" for gasoline/LPG, "D" for diesel — followed by two digits for the capacity class in hundreds of kilograms, such as D30 for 3.0 t or D45 for 4.5 t.

A trailing letter marks the chassis and equipment variant (e.g. "S" for standard), and a suffix like "-5" after a hyphen additionally marks the series generation on some lines. The database accordingly lists models such as D30G, D45S, D50C, D50S and G40S.
Models recorded here span engine outputs of 7.5 to 44.9 kW, capacities of 1,360.8 to 12,020 kg, and displacement of 2,000 to 8,000 cm³ — the bucket covers light through heavy counterbalance trucks.
Diesel trucks such as the D range suit outdoor work and heavy continuous loads best, since combustion exhaust needs adequate ventilation; LPG trucks in the G range can, thanks to their catalytic converter, also work in well-ventilated halls, while enclosed warehouses and food-handling areas usually call for electric counterbalance trucks with lead-acid or, increasingly, lithium-ion batteries.
For a used Doosan, the usual mast and axle-bearing checks apply, and on LPG models, the condition of the vaporiser and tank mount. Since the brand emerged through several corporate transitions (Daewoo to Doosan), it is worth checking parts availability for the specific series in advance on older units.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
- Compare the data plate and chassis number with the papers.
- Load the hydraulics and watch for sag.
- Ask about parts availability for this build year — the running costs hang on it.
