FAQs about ForkliftFrequently Asked Questions about Forklifts 1. What is a forklift? Answer: A forklift is a specialized vehicle designed to lift, lower, and move goods and materials in warehouses and factories easily and safely. It is equipped with front lifting forks and an engine for movement. 2. What are the most common types of forklifts? Answer: Some common types of forklifts include counterbalance forklifts, electric forklifts, pneumatic forklifts, and manual pallet jacks. Among them, electric forklifts are the most popular due to their flexibility, ease of use, and environmental friendliness. 3. What is the typical lifting range of a forklift? Answer: The standard lifting range of a forklift is usually between 2m – 5.5m depending on the type and capacity. For high-rise warehouses, taller lifting ranges up to 7-12 meters can be used. 4. What is the maximum safe load capacity of regular forklifts? Answer: The safe load capacity of regular forklifts ranges from 1 – 5 tons depending on the capacity and size of the vehicle. For heavy-duty forklifts, the load capacity can go up to 10-15 tons. Always follow the manufacturer’s recommended load limits to ensure safety. 5. What are the common fuel options for forklifts? Answer: Forklifts commonly run on electricity (battery) or diesel/gasoline fuel. Electric forklifts are preferred in indoor warehouses due to their clean operation, quietness, and ease of use. 6. How should a forklift be regularly maintained? Answer: To ensure proper operation and safety, a forklift should undergo regular maintenance every month or after a certain number of operating hours. Maintenance tasks typically include checking oil levels, replacing oil/fuel filters, inspecting brakes/tires, charging/replacing batteries (for electric forklifts), etc. 7. How much does it cost to operate and maintain a forklift annually? Answer: The annual operating and maintenance cost for a regular forklift is around 15 – 30 million VND, including fuel costs (diesel, gasoline, electricity), regular maintenance, and small component replacements. For higher-end forklifts, the cost can go up to 50-70 million VND per year. 8. How to safely lift and lower palletized loads with a forklift? Answer: When lifting loads, tilt the forks forward by 15 degrees to ensure stability, move slowly, and maintain a safe distance from the surroundings. Lift the load slowly according to the driver’s visibility. Lower the load slowly in a tilted direction. Avoid sudden lifting or lowering that may cause load spills. 9. What qualifications or certifications are required to operate a forklift? Answer: Forklift operators need to have certification in safe operation and handling of forklifts. They also need to possess a Forklift Driver’s License issued by the authorized agency to legally operate the vehicle. 10. What are the standard dimensions of different types of forklifts? Answer: The dimensions of forklifts vary depending on their load capacity and type. Typically, length ranges from 1.5 – 3m; width ranges from 0.5 – 1m; height ranges from 1.5 – 4m. Some models have smaller dimensions to fit narrow aisles. 11. On what types of terrains can forklifts operate? Answer: Forklifts can operate well on most flat surfaces such as concrete, asphalt, tiled floors, etc. However, they should not be used on rough or uneven terrains or muddy areas. 12. What is the safe traveling speed of a forklift when carrying loads? Answer: The recommended safe traveling speed for a forklift carrying loads is 8-12 km/h. Speed should be reduced when going around corners or narrow paths. 13. How to stack loads on a forklift to ensure safety? Answer: Loads should be stacked evenly and within the allowed load capacity. Do not stack higher than the fork height. Maintain stability while moving. Stack in a way that does not obstruct the driver’s visibility. 14. What safety features do forklifts have? Answer: Forklifts are equipped with reverse alarms, turn signals, warning horns, anti-tip frames, and guardrails to protect the driver and cargo. 15. How long does it take to fully charge an electric forklift battery? Answer: The average charging time for an electric forklift battery is 6-8 hours. It should be fully charged before each shift. Some models can have fast charging options within 2-3 hours. 16. Which countries are the most common sources of imported forklifts? Answer: Forklifts are mostly imported from Japan, South Korea, China, and Taiwan. These countries are known for their quality and popular brands in Vietnam. 17. What are some popular forklift brands? Answer: Some popular forklift brands include Toyota, Mitsubishi, Komatsu, Nissan, TCM, Hangcha, Lonking… 18. Is it better to buy a new or used forklift? Why? Answer: It is recommended to buy a new forklift to ensure quality and longevity of the vehicle. New forklifts have high durability, fewer breakdowns, and lower maintenance costs. Used forklifts may be cheaper but come with higher risks of issues. 19. How much does it cost to insure a forklift annually? Answer: The insurance cost for a forklift is around 4-8% of the vehicle’s value. For example, for a 500 million VND forklift, the insurance fee would be approximately 20-40 million VND per year depending on the coverage. 20. What is the process for inspection and registration of a forklift? Answer: Forklifts need to undergo inspection and registration procedures according to local regulations. This typically involves submitting necessary documents, paying fees, and obtaining registration plates or stickers.
