What Is LPG&Gasoline Forklift FG Series?
Feb 17, 2025
LPG Gas Forklift Truck is a dual-fuel forklift that uses liquefied petroleum gas (LPG) and gasoline as fuels. It is equipped with two independent fuel supply systems. During operation, the two systems supply fuel to the combustion chamber at a certain fuel ratio and burn it. Its features and maintenance methods are as follows:
Features
1) Wide range of applications: LPG burns relatively cleanly, with good exhaust emissions. The carbon monoxide (CO) emissions are significantly less than those of gasoline engines, making it suitable for indoor operations with high environmental requirements. At the same time, the gasoline power can also meet the various operation needs of the forklift outdoors.
2) Good power performance: The gasoline engine has a small external shape, light weight, large output power, and low working noise and vibration. The main component of LPG is propane, which has excellent anti-knock performance. Its octane number reaches over 120, and it is not prone to knocking phenomena. It can significantly reduce the noise of the engine. At the same time, due to full combustion and no carbon deposition, it can extend the major overhaul time of the engine.
3) High safety: The ignition point of liquefied petroleum gas is higher than that of gasoline, and its latent heat of vaporization is large, having a self-cooling effect. Moreover, the gas cylinder has undergone various safety tests and is equipped with an explosion-proof device, so it has high safety.
4) Good economic benefits: 15 kg of liquefied gas is equivalent to 20 liters of gasoline, and the fuel cost is low. In addition, the use of LPG can greatly alleviate the shortage of diesel and gasoline during peak periods in the region, diversify energy utilization, and avoid the impact of diesel and gasoline shortages on enterprise production.
Advantages Compared To Toyota Gas Forklift Truck
1) Flexible fuel selection: The dual-fuel system of the LPG&Gasoline Forklift provides additional flexibility in fuel selection. Toyota Gas Forklift Truck usually use a single fuel and lack this flexibility.
2) High cost-effectiveness: Generally speaking, Gas Powered Forklift Truck may have a relatively greater price advantage compared to Toyota forklifts, especially Chinese brand LPG&Gasoline forklifts. The purchase and operation costs are relatively low, and at the same time, the convenience and economic benefits brought by the dual-fuel can be enjoyed.
Maintenance Methods
1) Daily inspection: Check whether the oil level in the oil pan is at the specified scale position, whether the water radiator is filled with cooling water, and whether there are any water leakage phenomena at each water pipe joint. Check whether the gas cylinder outlet switch is turned on, whether there are any gas leakage phenomena at the joints of the gas circuit part. At the same time, check whether the battery is fully charged, and whether the connections of components such as the fan, water pump, and generator are reliable.
2) Engine start and operation: Turn on the ignition key and wait for about 2-3 seconds until the gas enters the entire gas circuit before starting the engine. If the engine fails to start four consecutive times, the cause of the failure should be checked. When the coolant temperature reaches 50°C and the oil temperature reaches above 40°C, the forklift can work under load. When using the rated power, the outlet water temperature should reach about 88°C. During the operation of the engine, it is necessary to pay attention to ventilation and check the gas circuit, operation sound, etc. If any abnormal situation is found, the engine should be stopped immediately for inspection.
3) Parking and storage: Before the engine stops, the load should be gradually reduced and the speed should be decreased to make the engine run idly. When the outlet water temperature drops below 70°C, turn off the gas cylinder outlet switch at this time, and then turn off the switch to stop the engine. If the engine needs to be stored for a long time, it is necessary to clean the exterior of the engine, ensure that the gas cylinder is installed firmly without looseness, and there is no leakage at the valves, pipelines, and joints, etc. A series of maintenance operations should also be carried out on the engine, such as discharging the gas and lubricating oil, replacing the lubricating oil filter element, and discharging the coolant, etc.
4) Handling of special situations: In cold regions, after the first start, the engine must be run for 2-3 minutes before starting again, so that the engine coolant can heat the pressure reducer to make it work properly. If the outside of the pressure reducer is frosted or iced, the outside of the pressure reducer can be slowly poured with hot water or the cooling water inside the pressure reducer can be replaced with heated cooling water until it becomes hot, and then start again.
