How to select the gear oil for electric hydraulic forklift?

As we all know, the commonly used lubricants on internal combustion forklift are engine oil, gear oil, hydraulic transmission oil, hydraulic oil and grease. However, as a kind of logistics and storage equipment widely used in recent years, electric hydraulic forklift is not well known for many maintenance knowledge. The commonly used lubricants on electric hydraulic forklift include gear oil, hydraulic oil and grease. Today, Electric forklift manufacturer will start with gear oil and tell you how to select gear oil for electric hydraulic forklift.

The American API vehicle gear oil classification is adopted for the classification of electric hydraulic forklift gear oil in China, which is divided into three categories: ordinary load, medium load and heavy load vehicle gear oil. There are seven viscosity brands, namely 70W, 75W, 80W, 85W and 90, 140, 250. Where, W represents winter gear oil. When we choose gear oil, we should look at the quality level and viscosity grade. The quality level shall be selected according to the gear type and working conditions, and the viscosity grade shall be selected according to the lowest ambient temperature and the highest temperature of traditional device operation. Electric forklift manufacturer will give you a specific explanation.

The minimum operating temperature of 70W gear oil for electric hydraulic forklift is - 40 °, that of 80W is - 26 °, that of 85W is - 12 °, that of 90 is - 10 °, and that of 140 is 10 °. You should choose according to your city and different seasons. When using, it should be noted that on the basis of meeting the viscosity requirements, the gear oil with low viscosity grade should be selected for the electric hydraulic forklift, because too high viscosity grade will reduce the transmission efficiency. The gear oil shall be replaced in time, and different brands of gear oil shall not be mixed. The electric forklift manufacturer reminded that if it is necessary to replace the gear oil of different brands of vehicles, it is necessary to drain all the gear oil of the electric hydraulic forklift before replacing it.

The above is the selection of gear oil for electric hydraulic forklift and the precautions for use. We should make choices according to our working environment and the conditions of electric hydraulic forklift. Electric forklift manufacturer believes that the right choice is on the one hand, and correct use and regular maintenance are also very important. Enterprises and drivers must pay more attention.
