How to select lubricating grease for electric forklift?
When we talked about lubricants for electric forklift, we mentioned gear oil and hydraulic oil in detail. Another common lubricant used on electric forklifts is grease. On electric forklifts, the lubricating grease is mainly used for the pin shaft parts of the transmission system, driving system, steering system and other relative movements, usually including calcium based grease, calcium sodium based grease, lithium based grease and industrial vaseline. We usually use calcium based grease and lithium based grease. Now, the electric forklift manufacturer will tell you how to choose the lubricating grease for electric forklift.
When selecting the lubricating grease for electric forklift, the performance and consistency grade of the lubricating grease shall be mainly considered. The commonly used consistency grades are Grade 2 and Grade 3. The greater the load is, the higher the consistency grade of the grease needs to be selected. Under the condition of meeting the use requirements, try to use low consistency grease, which can reduce power consumption. How to choose between calcium based grease and lithium based grease? Let's take a look at their advantages and disadvantages. Calcium based grease has better water resistance, is easy to adhere to metal surfaces, and has better stability, and is applicable to the temperature range of - 10 ° C to - 65 ° C. Its disadvantage is poor heat resistance. If it exceeds 100 ° C, it will lose its consistency. It is not applicable under heavy load and high temperature. Lithium based grease has good water resistance and stability, and is not easy to be oxidized. It is applicable to the temperature range from - 60 ° C to 120 ° C. Its disadvantage is that the price is relatively high. Therefore, the electric forklift manufacturer tells you that in general, calcium based grease is used less and less, and lithium based grease is used more and more widely.
What should be paid attention to when using grease for electric forklift? We must add lubricating grease regularly and quantitatively according to the requirements of the manual of the electric forklift and the specified brand. It shall be noted that the lubricating grease of different brands shall not be mixed. During the use and storage of lubricating grease, keep it clean, avoid the intrusion of foreign substance and moisture, and minimize the contact between lubricating grease and air. When replacing the lubricating grease, the bearing shall be cleaned and kept dry. The electric forklift manufacturer reminds everyone not to use grease when the electric forklift is fully loaded, because it will affect the braking efficiency as the temperature rises and cause waste.
The above is how to select grease for electric forklift and the precautions when using grease. The electric forklift manufacturer told us that lubricants are essential for electric forklifts. The use of lubricants can not only improve work efficiency, but also avoid many unnecessary troubles. When using lubricants, be sure to follow the requirements, otherwise it will only cause reaction.

New energy forklift power system controllerIn the electric forklift power unit, when the forward contactor is closed, the motor is in a forward rotation state; Whereas, when the reverse contactor is closed, the motor is reversed. By changing the direction of the armature current or excitation current, or by changing the polarity of the excitation winding, the commutation control of the motor is realized. However, the use of two sets of excitation windings with opposite windings will lead to a complex structure and an increase in the volume of the motor, so the first two methods are more commonly used in practicalDo you like ?0

Electric forklifts vs. internal combustion forkliftsHowever, there are also some drawbacks to internal combustion forklifts. First of all, diesel engines are more expensive to run, especially against the backdrop of the current surge in oil prices. Secondly, the internal combustion forklift is noisy and vibrate, and the operating noise of the diesel engine has an irreversible impact on the human body. In addition, the exhaust gas pollution is serious, even if the processor is installed, it will cause environmental pollution, and it is necessary to clean up the dust regularly, which is more cumbersome to maintain, and can easily lead to oil pollution problems on the site.Do you like ?0
