The core component combination of the hydraulic system directly determines the basic response speed of lifting and lowering actions. Most standard electric forklift hydraulic systems consist of power-supply driven hydraulic pump, multi-way control valve, lift cylinder, pressure regulating unit and connecting pipelines, and different configuration schemes will form obvious performance differences in actual operation.

For the lifting performance dimension, the displacement matching of the hydraulic pump with the output power of the driving motor is the core factor. If the configuration matches reasonably within the safe load range, the lifting action can maintain a steady rising speed without obvious jitter, and will not produce abnormal pressure surge when reaching the maximum lifting height. The flow distribution design of the multi-way control valve also plays a key role: the configuration with independent flow adjustment structure can allocate corresponding flow according to the real-time load weight, so as to avoid the situation that the lifting speed drops sharply when carrying heavy loads, which effectively improves the operation consistency under different load conditions.

As for the lowering performance, the balance valve configuration on the loop of the lift cylinder is the key link to prevent accidental sliding during the lowering process. The configuration with integrated balance buffer structure can automatically adjust the oil return flow according to the gravity of the goods, which can avoid the obvious free fall jitter at the moment of starting to lower, and keep the whole lowering process smooth and controllable. The inner diameter and layout of the return oil pipeline also have non-negligible influence: the configuration with smooth bending transition and reasonable pipeline inner diameter can reduce the oil return resistance effectively, avoid excessive negative pressure inside the cylinder when lowering at medium and high speed, and reduce the abnormal noise generated during the action.

Reasonable hydraulic system configuration can also reduce unnecessary energy consumption in the process of frequent lifting and lowering operations. The optimized configuration scheme does not need to bear extra unnecessary pressure loss, which can extend the continuous working time of the electric forklift under the same battery capacity condition. In daily use and maintenance process, operators and maintenance personnel can also adjust the relevant configuration parameters within the allowable range of the equipment specification according to actual common working conditions, so as to make the lifting and lowering performance of the electric forklift more suitable for specific operation scenarios, and improve the overall operation safety and handling efficiency.
