What Factors Should Be Paid Attention To When Choosing A Hydraulic Lift

Synchronous lifting, when we choose hydraulic lifting equipment, consider the following important factors:

1. Stress

The level of pressure and the length of the pressure cycle change have a great influence on the damage of hydraulic lifting equipment. The higher the pressure, the greater the impact of other factors on the performance of the hydraulic lifting equipment, such as temperature, speed, the material of the hydraulic lifting equipment, the gap between the piston and the cylinder, and the gap between the piston and the cylinder head.

2. Temperature

It is difficult to describe the high use temperature and low use temperature of a hydraulic lifting equipment material, because it is the result of a series of factors.

3. Friction

The friction of hydraulic lifting equipment and sealing surface depends on many factors: surface roughness, surface characteristics, pressure, medium, temperature, material of hydraulic lifting equipment, type and speed of movement of hydraulic lifting equipment.

4. Surface treatment

Experience has shown that the characteristics of the cylinder piston and piston rod surface have a great influence on the life of hydraulic lifting equipment. Surface characteristics are often defined by the value of surface roughness Ra, which is the arithmetic mean value of the deviation of the surface shape from the line. However, these values do not indicate the effect of surface conditions on hydraulic lifting equipment. This is because even under the same roughness, different surface shape characteristics can lead to different degrees of hydraulic lifting equipment wear.
