The components of the hydraulic system are the same as those of our traditional forklifts and excavators, but why are the hydraulic systems of car carrier trailer prone to failure? First, most of our drivers do not understand the principles of hydraulics very well. Although The main components of the hydraulic system are the same as those of other engineering vehicles, but the hydraulic system of the engineering vehicle is much simpler. During use, the system cannot be left in a non-working and running state for a long time, which will cause the system to overheat and cause damage. Failure and scrapping. Therefore, the hydraulic system must be allowed to work when in use. After lifting, the hydraulic system must be shut down immediately. In addition, hydraulic oil has a similar principle to engine oil and must be checked and replaced regularly. Deteriorated hydraulic oil will also Damage to the system so that the main components of the hydraulic system are scrapped, as well as the quality and cleanliness of the hydraulic oil, are also key. In short, most of the damage to the hydraulic system is caused by human factors.
