DongYang Elevators with newly developed MRL Elevator and DY20GL.
DongYang Elevators is ready to launch the machine-room-less elevator MRL. DongYang Elevators indicated that the machine-room-less elevator concept will soon be the core product range in the new installation market segment. Dong Yang explains "The conventional type of traction elevators require the machine-room equipment such as traction machine, controller and governor at a separate machine room. The advanced technology enables the permenent magnet motors and slimmed contoller to eliminate the machine room." DongYang likely developed the machine-room-less elevator system for both machine above and below arrangement. The machine above type of machine-room-less elevator will soon be installed at a new building by coming May 2001. " Dong Yang speeds up the development of high speed range of machine-room-less elevator system by 2002." said Dong Yang. DongYang also introduced the high speed product range DY20GL. The speed range meets upto 420 m/m. The system configuration is as follows; Digiral circuitary applied to motor control that improves the riding perfomance. Integrated Multi-protocal Processor(IMP) enables control function, and all the data transmission uses optical wire system. Fuzzy logic applied to artificial intelligence group dispatching system that minimizes the passenger waiting time. |
