为MRDS型电梯改造而设计，采用曲臂传动、二级减速，减速比为1：35，使门运动状态更加舒适平稳。电气接口适应范围大，串行、并行两种通讯方式可选。机械连接上采用OTIS电梯连接方式，与OTIS系列MRDS、TOEC-40、TOEC-60等都可方便连接，也可与其他电梯配套使用。在与新梯配套时，只要将HAD-Ⅱ型开门机坐于轿顶即可使用。在进行老梯改造时原有门导轨、门刀、门锁、门吊板都不需更改只要将HAD-Ⅱ型开门机安装于轿顶即可使用。大幅压缩了改造成本。
Designed specially for MSDS elevator transformation, it adopts crank arm transmission and tow-step speed reduction (Speed reduction ratio is 1:35) to ensure that doors can move comfortably and smoothly. Large electric interface range and serial and parallel communication are optional. Its mechanical connection adopts OTIS elevator’s connection methods and can be connected to OTIS MRDS, TOEC-40 and TOEC-60 easily and also can be used together with other elevator type. When it is used with a new elevator, we can simply put it on the top of the car roof. When an old elevator is transformed, there is no need to alter the Door Guide, Knife Gate, Door Loch or Door hanger plate and what we should do is simply put it on the top of the car roof. That will save many transformation costs.
Suitable for the door opening width: 700mm－1100mm (center opening )
