System Description

The screen door system is ahigh-tech product combining advanced knowledge of architecture, mechanics,electronics , materials and information technology, Which is mainly used in therapid transit area, such as subway, city rail, high-speed railway. The screendoor system is installed at the edge of platform to separate the rail area andthe waiting area, which effectively reduces power consumption of theenvironmental control equipments in the station, and prevents ventilation lossof the air-conditioning system, ensuring a comfortable waiting environment forthe passengers. The screen door is also a station security system for safedriving and waiting.
Dinghan screen doorsystem is independently developed by Dinghan Technology, with 3 patents ofinvention, 2 patents of utility model, 6 patents of appearance and 1 softwarecopyright.

FineStructural Design

Inventionpatent of gate lock and a number of patents of utility model and appearance;

Finedesign of the control mechanism ensures easy and comfortable operations;unlocking handle not only gives excellent hand feeling to operators, but alsomeets the requirements of human instinctive actions in emergencies;

Theoperating and maintenance positions are centralized as much as possible, toreduce difficulty of operation during maintenances for easy overhaul;

Thematerial selection in anti-pinch design and the slope angle of anti-standingpedal take full considerations of passenger feeling to make all reasonable;

Aluminumand stainless steel can be used according to different requirements.
