If the forklift will move continuously between warehouse doors, open yards, trucks, and uneven ground, diesel usually offers a simpler and more stable operating setup.
Attachment weight also matters. Side shifters, clamps, or longer forks can change the true working load, so the buyer should confirm the real duty condition instead of choosing only by nominal capacity.
For export projects, tyre type, mast stage, engine option, and the first spare parts list should be decided together. That produces a more accurate quotation and a more reliable first shipment.
