At the same time, when the hydraulic buffer column 21 moves down, the oil pressure in the hydraulic adjustment box 123 will increase, thereby pushing the sliding pressure regulating cylinder 23 to move up, causing the hydraulic adjustment spring 24 to compress and further compress the vibration. At the same time, the height sensor will identify the upward movement amount and upward movement frequency of the sliding pressure regulating cylinder 23, identify the uneven road surface at this time, and send an electrical signal to the adjustment motor 362, so that the output shaft of the adjustment motor 362 retracts, so that the compressible amount of the compression deformation groove 365 in the installation connection plate 363, the buffer spring 359 and the rubber buffer cylinder 357 increases, that is, the buffer adjustment element 35 becomes "soft" to buffer the vibration generated by driving. At the same time, the height sensor will send a signal to the first transverse clamping cylinder 65 and the second transverse clamping cylinder 68, causing the first transverse clamping cylinder 65 and the second transverse clamping cylinder 68 to slightly retract, so that the two clamping forks 66 move slightly inward along the adjusting slide column 642 and the synchronous slide rail 643 synchronously, so as to enhance the clamping force of the goods in the fork assembly 60 and prevent the goods from falling during driving.

[0044] For example, in one embodiment: when it is necessary to clamp overweight cargo, the center of gravity of the forklift will be shifted toward one end of the adjacent fork assembly 60, so that the center of gravity of the forklift cab 40 will be shifted forward synchronously, the downward pressure on the hydraulic buffer column 21 will be reduced, the hydraulic adjustment spring 24 will rebound, and the sliding pressure regulating cylinder 23 will move downward. The height sensor will identify the downward movement of the sliding pressure regulating cylinder 23 and send an electrical signal to the adjustment motor 362, so that the output shaft of the adjustment motor 362 will extend, and the compressible amount of the compression deformation groove 365 in the mounting connection plate 363, the buffer spring 359 and the rubber buffer cylinder 357 will become smaller, so that the buffer adjustment element 35 will become "hard", so as to provide better support for the forklift, improve the carrying capacity, prevent the forklift from sinking under the overweight load, and prevent rollover or loss of control.
