First of all, let's talk about the advantages of internal combustion forklifts:
1, internal combustion forklifts are diesel-powered, not easy to stall at low speed, with strong overload capacity and long-time operation capability;
2, strong adaptability to the environment and the ability to work in difficult environments;
3, low road requirements, high operational sensitivity, mostly pneumatic tyres, no damage to the ground, good fitness effect.
Disadvantages:
1, high cost of diesel power, now soaring oil prices.
2, large noise, vibration, diesel engine operation noise on the human body caused by irreversible impact.
3, the exhaust gas pollution, even if the processor pollution, regular cleaning ash, very troublesome; engine maintenance trouble, not clean, often oil.

Coming back to the advantages of electric forklifts:
1, electric forklifts are driven by motors, low noise, the noise of brushless motor driven forklifts is similar to the sound of our trams;
2, easy maintenance of the motor, brushless motors generally have a life of tens of thousands of hours and maintenance requires only attention to the hydraulic system;
3, no exhaust emission, no pollution, greatly reducing the harm to human body, suitable for factory and indoor use.
Of course, there are inevitable disadvantages of electric forklifts.
1, The biggest disadvantage is that the power is not durable, a full charge can last for about 8 hours.
2, The charging time is also relatively long, generally about 5-8 hours (many forklifts are now equipped with high power fast charging, the specific time varies slightly).

If you need to work for a long period of time, you could suggest adding more batteries or an additional battery pack, or buying some batteries as a spare replacement. In addition, internal combustion forklifts can increase the throttle and accelerate upwards, whereas electric forklifts can only rely on motor driven hydraulic cylinders to raise slowly.
