Internal combustion forklifts are large in size, but have good stability and are suitable for heavy loads. There is no time limit for use. The place of use is generally outdoors. Compared with gasoline engines, diesel engines have better power performance (not easy to stall at low speed, strong overload capacity, strong long-term running ability), and low fuel cost. But they have large vibration, high noise, large displacement, high dead weight, high price and large load. Volumes vary from 0.5 tons to 45 tons.
Internal combustion LPG forklift for short is a counterbalanced gasoline forklift equipped with a liquefied petroleum gas conversion device, which is called an LPG forklift, and can be switched between gasoline and liquefied gas through a changeover switch. The biggest advantage of LPG forklift is that it has good exhaust emissions, carbon monoxide (CO) emissions are significantly lower than gasoline engines, and fuel costs are low (15KG liquefied gas is equivalent to 20 liters of gasoline), which is suitable for indoor operations with high environmental protection requirements.
Forklift maintenance does not slow down when turning, driving when the load is increased, the forklift is overloaded, driving on inclined or soft ground, etc. The driver should try to avoid these unsafe operations when operating. When charging the battery for forklift maintenance, the charging circuit must be completely separated from the chopper, because in addition to affecting the charging of the charger, the overvoltage generated by the charger will also damage the chopper.
