式 升降平台 （以下简称“ 升降平台 ”）是一种垂直升降作业的简易 升降平台 ，采用液压油缸顶升、链条及钢丝绳拉动工作台，起升到目标高度后，通过限位开关自动与楼层平层。 The rail -type lifting platform (hereinafter referred to as the " lifting platform ") is a simple lifting platform for vertical lifting operation . It uses hydraulic cylinders to lift, the chain and the wire rope pull the table. After lifting to the target height, it automatically communicates with the floor through the limit switch Flat layer. 升降平台 结构上加装极限限位开关，防止平层限位开关失效 升降平台 继续升降造成危险事故。 The limit platform switch is installed on the lifting platform structure to prevent the leveling limit switch from failing and the lifting platform will continue to lift and cause dangerous accidents. The steel wire rope plays the role of left-right synchronization and safety against falling. When the chain breaks suddenly, the wire rope can make the workbench stop instantly in this position instead of the workbench falling sharply. Play a safety protection role. 升降平台 不工作，起到安全防护作用。 A pressure sensor is installed in the hydraulic oil circuit. When the rated load is exceeded, the working pressure increases. The power of the motor is cut off by a control signal, and the lifting platform does not work, which plays a role of safety protection. The safety factor of the whole machine is designed to be 125%, and the safety factor is large. 升降平台 转动结构加装优质轴承，减少刚性摩擦，有效提高设备的使用寿命。 Install high-quality bearings on the lifting platform rotation structure to reduce rigid friction and effectively increase the service life of the equipment.
