With the development of China's economy and the rapid increase of the urban population, the consumption level of the people is increasing day by day, and the society's demand for refrigerated food is also increasing rapidly. As an important equipment for logistics and transportation in the cold storage industry, forklifts play a very important role in the operation of the cold storage industry. Due to the particularity of the cold chain industry, the use of forklifts considers the working ability in low temperature environments. So, do you know what factors need to be considered in the selection of diesel forklifts?
Influence of low temperature environment on battery capacity
The calibration of battery capacity is based on an ambient temperature of 20°C and standard air pressure. The lower the ambient temperature, the less capacity the battery can actually use. Generally speaking, in a low temperature environment of -20C, the actual capacity of the battery is only 80% of its rated capacity. Therefore, an electric forklift that can meet the requirements of use time in a normal temperature environment may not meet the requirements of use time in a low temperature environment. The battery capacity needs to be increased appropriately.
The effect of temperature difference on electric forklifts
In most cases, forklifts need to work alternately in low and normal temperature environments. In this case, condensed water is likely to be generated, which can cause damage to electrical equipment.
Forklift trucks are designed and maintained with this in mind. Otherwise, the electric forklift will fail frequently, and it is very likely that it will not work properly.
The effect of humidity on the body
There are many cases of high humidity in low temperature refrigerators. Due to the rust of some parts and structures of the forklift, the forklift should be protected to avoid serious rust or damage.
Requirements for anti-skid in cold storage environment
Humidity is high in the refrigerator and the floor is wet and slippery, sometimes freezing. In this case, the forklift has good anti-skid ability. Forklifts are equipped with skid tires, but this is often not enough. When the forklift is loaded, the front wheel load is large, the rear wheel load is small, and the friction between the rear wheel and the ground becomes smaller, and sometimes side slip occurs. Therefore, electric forklifts for cold storage need to consider choosing a model with a larger tonnage to ensure that the load on the rear wheel remains large after loading and avoid tire slippage.
Influence of low temperature environment on hydraulic system
Hydraulic oil and hydraulic high-pressure hoses used at room temperature tend to become viscous and brittle at low temperatures, and are not suitable for use at low temperatures. Therefore, in order to avoid failures and safety accidents,
electric forklifts for freezers use special hydraulic oil and high-pressure hoses.
Influence of low temperature environment on mechanical system
The properties of lubricating oils and greases used at room temperature will also change at low temperatures, so they are not suitable for use at low temperatures. Please also use special grease and grease for this part. Some electric forklift components, such as micro openers, sensors, bearings, etc., also require the use of specially designed parts.
