以DO2000为设计原型，采用支架形式，结构简单紧凑、全同步带传动，安装方便，电器接口适应范围大，串行、并行、三线编码三种通讯方式可选。机械连接上采用OTIS电梯连接方式，也可与其它电梯配套使用。在与新梯配套时，只要与门导轨、门刀、门锁、门吊板连接上即可。在进行老梯改造时原有门导轨、门刀、门锁、门吊板都不需要更改，只要重新连接即可。可以大幅缩减改造成本。
Type HAD—Ⅰdoor operator
With it designed being based on French DO2000, it is of a support type, being characterized by simple structure, compactness, synchronous belt transmission, easy installation, large electromechanical interface range and serial, parallel and three wires encoder communication (optional). Its mechanical connection adopts OTIS elevators connection methods and it can also be used together with other elevators type. When it is used with a new elevator, only need to connect it to the Door Guide, Knife Gate, Door Lock and Door hanger plate. When an old elevator is transformed, there is no need to alter the Door Guide, Knife Gate, Door Lock or Door hanger plate and what we should do is simply connect it to them again, hence a great reduction in transformation costs.
Suitable for the door opening width: 700mm－1150mm (center opening and side opening )
