摘　　要：固定式伸缩臂叉装车在臂架运动过程中,整车重心是不断变化的。为保证叉装车的作业安全,以TH4518型伸缩臂叉装车为例,设计一套行之有效的叉装车安全控制系统。根据重心法计算伸缩臂叉装车载荷图,并分析横向力矩保护系统的组成和原理。设计相关程序,确保车架在左右调平及工作过程中,不超过安全作业区域的范围,使整车处于安全状态,不会发生倾翻。经实际运行验证,所设计的安全控制系统稳定可靠。During the movement of boom of fixed variable-reach forklift loader,the center of gravity of the whole vehicle is constantly changing.To ensure the operation safety of the forklift loader,taking a TH4518 variable-reach forklift loader as an example,a set of effective safety control system for the forklift loader is designed.The load diagram of the variable-reach forklift loader is calculated according to the center of gravity method,and the composition and principle of the lateral torque protection system are analyzed.The relevant programs are designed to ensure that the frame does not exceed the range of safe working area during left and right leveling and operation,so that the whole vehicle is in a safe state and will not roll over.The designed safety control system is stable and reliable as verified by practical operation.
