SRH GRA10 Car Elevator Micro-computer signal control system

GRA10 car elevator utilizes new data processing net work. Landings and cabin of GRA10 car elevator are allocated with computer controp system(CPU). They have been connected through serial transmission lines. It reduces the connecting lines amid various parts and results in more efficient and precise system control. The diagnosis program and backup system amid various computers ensure the high reliability of the parts connection. Each computer specially sets the software with resoning ability. It enrices and perfects man(car)-elevator interface. 

We utilize the advanced and large-scale programmable gate array into the car elevators. We fulfill the monolithic intergration of the system, largely enhance the anti-inteference of the system with the more simple operation and the more sensitice reaction.

The safe door protection device

Car is the durable and  high-grade consumer goods, therefore security is extremely important. GRA 10 car elevator has two independent photo-eletric devices in the entry of every of every landing.  Front and rear car door respectively has infrared optical curtain devices. Therefore it is safer for the car entry/exit. In addition, the car entry/exit landing has landing door alarm lap. After pressing floor command in the car, the corresponding landing ffor announcer lamp will be bright. It warns the people and drivers in the landing entry/exit that the car comes in the lading so as to ensure the security of both the people and the cars. 

The matured variable voltage and variable frequency technology

GRA 10 car elevator adopts the highly matured variable voltage and variable frequency(VVVF) Control technology. We implement the extremely precise speed governor control through special frequency converter which effectively enhance the travel smoothness and save the energy as well. 

GRA 10 car elevator extends VVVF control technology from elevator drive system to the door machine system in order to increase the car safety in entry&exit. Plus the matching none link rod door machine, elevate the sensitivity of the elevator door switch, automatically adjust the most appropriate open/close speed of each floor. In this way, the cars can more freely enter into and exit from car elevator. 

Hydraulic car elevator

GRAH10 Serial hydraulic car elevators use Italian GMV hydraulic system with a combination of the mature and reliable PC control technology. Apart from all the safety protection devices of traction type elevators, we additinally add the mutiple hydraulic circuit protection systems such as safrty valve, speed limit disconnecting valve tec. to ensure maxximum standard of the travle quality and decurity.

The machine rooms that install the drive and control devices can ensure the wanton position of no more than 15m length oil distributing pipe in the shaft according to different architectual designs. It suits the constructions which can not have top machine rooms. Meanwhile it utilizes the current space as far as possible.
