Forklift Basics

Forklifts are a relatively recent type of lifting and transport machinery. The world's first forklift was launched by Clark Company of the United States in 1932, and subsequently developed rapidly, particularly after World War II, when the variety and output of forklifts in European and American countries increased dramatically. Currently, the countries with the largest forklift production are the United States, Japan, Germany, the United Kingdom, and Bulgaria. China began producing electric forklifts in 1954 and internal combustion forklifts in 1958. Currently, China manufactures a wide variety of forklift models. In terms of lifting capacity, China can manufacture forklifts ranging from 0.5 to 50 tons. Since China's reform and opening up, new technologies and devices have been introduced and developed. Features such as hydraulic steering, hydraulic torque converters, constant mesh gear hydraulic shift transmissions, planetary wheel-side reducers, and high-strength, wide-view masts have been adopted in forklifts, resulting in easier and more efficient operation, improved maneuverability, enhanced safety and reliability, and increased work efficiency.

What are the main parts of an internal combustion forklift?

1. Engine: This is the power unit of the forklift, whose function is to convert thermal energy into mechanical energy. The power generated by the engine is output by the crankshaft and drives the forklift to travel or drive the hydraulic pump to work, completing operations such as lifting and stacking goods. 2. Transmission system: This includes the clutch, gearbox, main transmission, differential, half-shaft, etc. The function of the transmission system is to transmit the power output by the engine to the hydraulic pump and drive wheels, realizing the lifting, tilting, and traveling of the forklift. 3. Operating system: This includes two parts: the steering mechanism and the braking system. The basic function is to change the traveling direction of the forklift, reduce the operating speed, or stop quickly to ensure the safety of loading and unloading operations. 4. Working system: This includes the inner and outer frames, fork frame, forks, lifting chains, rollers, pulleys, etc. Its function is to lift, lower, or stack goods. 5. Hydraulic system: This includes the oil tank, hydraulic pump, distributor, lifting hydraulic cylinder, tilting hydraulic cylinder. Used to realize the lifting and tilting of goods. 6. Electrical system: This includes the power supply part and the power consumption part. It mainly includes batteries, generators, starting motors, ignition devices, lighting devices, and horns, etc.

The importance of safe forklift operation

Safe operation of forklifts mainly refers to three aspects: safe driving, safe operation, and safe maintenance of forklifts. From the perspective of accidents caused by forklift use, it generally involves people (drivers, loaders, pedestrians), vehicles (both vehicles), road environment, and a combination of the three factors. In general, the driver is a major cause of accidents, and those directly responsible account for more than 70%. Operation is achieved through human intervention between the vehicle and the operating environment. The control and driving devices of the vehicle constitute a human-machine control system. A person's psychology, physiology, emotions, and reactions, judgments, and processing of external environments and information directly affect driving safety. That is, in the human-machine control system, the driver exists as the central nervous system of the human-machine control system, and the driver's operating characteristics directly control the safe operation of the human-machine control system. When the driver is driving a vehicle on the road, information is obtained from the external and internal environments of the vehicle, and is transmitted through sensory organs such as vision, hearing, touch, and pressure to the central nervous system in the brain. After the driver makes a decision through thinking and judgment, it is transmitted by the nervous system to the effector (hand, foot, etc.), thus controlling the vehicle. If there is a deviation in the reaction of the effector during driving, the information stimulus is returned to the central nervous system for correction. This return is called feedback, so that the vehicle can drive according to the driver's will. In the above human-machine adjustment system, the driver exists as the central nervous system of the moving motor vehicle; therefore, the driver's will, desires, emotions, mood, fatigue level, physical condition, illness, alcohol, drugs, etc., have an important impact on the human-machine adjustment system. In other words, the driver's operating characteristics are extremely closely related to driving safety.

What are the reasons for electric forklift battery smoking?

1. During the discharge process of electric forklift batteries, gas emission sometimes occurs. This is because the electrolyte contains impurities after the electric forklift battery is charged and left aside. It is recommended to discharge after one hour or replace the electrolyte. 2. A small amount of gas emission occurs in the later stage of battery charging. This situation in electric forklifts is likely due to a slightly lower charging current or the battery not being fully charged. In this case, adjust the current and charge. 3. No gas emission after charging the battery of a battery forklift. This is because a short circuit may have occurred inside the battery. Stop charging and check for short circuits. 4. The battery of a battery forklift emits gas too early during charging, or a large amount of gas is emitted. This may be due to sulfation of the battery plates.
