叉车装设按钮点火开关启动的合理性剖析

Analysis on reasonability of starting of forklift with ignition switch button

随着技术的快速进步,一键启动装置在汽车领域普及,甚至出现了叉车装设按钮点火开关启动的案例。在国家尚未出台明确技术要求的情况下,文中针对所遇到的叉车案例展开合理性剖析,结合其他行业标准和实际经验,从按钮开关、接线原理、电源总开关、未经允许的启动等方面系统阐述其技术要求,明确叉车按钮点火开关应采用和不允许采用的操作器类型、颜色,阐述单挡位、三挡位和四挡位的接线原理,分析所遇案例简单地将原厂四挡位开关合并为单挡位启动的危害,提出叉车必须有单独的电源总开关挡位,认为叉车不允许装设单挡位点火开关,提出叉车应避免未经允许的启动及叉车装设开关的适用程序。

With the rapid development of technologies, the one-button startup device is widely applied in the vehicle field. Some forklift isinstalled with a button ignition switch. Against the background that China has not issued the explicit technological requirements, the paper analyzes the example of the forklift, describes the technological requirements on the button switch, wiring theory, battery main switch, and unapproved startup based on other professional standards and experi- ence, specifies the model type and color of the manipulator that can or cannot be used for the button ignition switch, ex- pounds the wiring theory of single gear, three gears, and four gears, analyzes the risk of combining the original four-gear switch to a single-gear switch, and presents that the forklift must be provided with an independent battery main switch. It＇s not allowed to install the single-gear ignition switch in the forklift and the forklift shall prevent unauthorized startup. Fur-thermore, the paper also puts forward applicable procedures for installing switches in the forklift.
