Hydraulic trailer-do you know enough about the height of it part 1?

What is Hydraulic Modular Trailer height?

Trailer height means the height of the cargo platform of the trailer. Since the trailer is a hydraulic independent suspension, corresponding to the maximum stroke position and minimum stroke position of the suspension hydraulic cylinder, the height of the trailer can be adjusted within a certain range. The trailer height is often expressed in the form of D ± e. For example, the identification of a trailer is 1190mm ± 325mm. Where, D is the normal operating height of the trailer, generally the distance from the midpoint of the lifting amplitude of the trailer to the ground, and E is 1 / 2 of the lifting amplitude of the trailer, also known as the lifting amount of the trailer.

From this, it can be calculated that the maximum and minimum height of the trailer under the theoretical state can be expressed by the formula.

The maximum and minimum height of the multi axle trailer in actual operation are affected by the following factors:

Due to the different sinking amount of trailer tires with the change of load, the sinking amount of common hydraulic flat trailer tires (model 8.25r15 or 7.50r15) may reach about 50mm under large load, while the trailer running height D and trailer lifting amount e given in the technical performance data of general Trailer manufacturer are often the values under a certain load state (empty vehicle or common axle load), Therefore, the influence of tire deformation after loading should be considered in the height of trailer.
