The invention provides a forklift overturn-preventing device. Two single-acting hydraulic cylinders are installed on the two sides of the center of a forklift frame; piston rods of the hydraulic cylinders abut against a bogie; and oil ways of the two hydraulic cylinders are communicated through a normally-open electromagnetic valve. The forklift is further provided with a single-chip microcomputercontrol system and two sensors. When the single-chip microcomputer calculates that the turning speed of the vehicle is too high, a power module drives the electromagnetic valve to work to close the oil way, and the piston rod of the hydraulic cylinder abutting against the bogie cannot retract, so that the frame cannot incline, the center-of-gravity shift of the vehicle is reduced, and the anti-overturning capacity of the vehicle is improved.
一种叉车防倾覆装置,在叉车车架中心的两侧安装2只单作用液压缸,液压缸的活塞杆顶住转向架,2只液压缸的油路通过一个常开电磁阀联通。叉车上还安装一个单片机控制系统和2个传感器。当单片机计算出车辆转弯速度过高,通过功率模块驱动电磁阀工作将油路关闭,顶住转向架的液压缸活塞杆不能回缩,使得车架无法倾斜,因而减小车辆重心偏移,提高了车辆的抗倾覆能力。
