Hospital elevator

Hospital elevator,is a kind of elevator design for transporting hospital beds, stretcher, medical vehicle and patient.So the car cabin is with long length,and always with handrail for wheel chair patient.It is a vertical lift based on motor power with car cabin and service for certain floors.

Almost the hospital elevator use the side opening door.The advantages of side opening as below:

1.Door opening speed is very quickly.Time means for life,it’s very important in hospital.Even 5 seconds can save a life.

2.To save the elevator space.We should know,side opening door is open from left or right side,while there are still two door panels,one in front and another behind.When the door is fully opened, the two doors panels are stacked together.The elevator door is installed in the cable well,to occupy the space of the cable well, this can save 1/4 space.For example,if each door panel is 1.5m,the door width 3m.If use the normal center opening will take 6 meter space,while is only 4.5m for side opening door.

In addition, if you look carefully, you will find that the hospital elevator is larger  than the normal passenger elevator,because the hospital has a large flow of people.While the shaft space is not so larger compare to normal elevators due to the side opening door.

Application of PLC in medical elevator

1.Rational use of PLC hardware resources and software resources,ensuring the safety of the elevator, reliable operating conditions,reduce the PLC input and output ports, make full use of a variety of instructions to simplify the control program.

2.PLC control procedures should have the ability to optimize the logic of judgment, so that to make the most reasonable operation of the elevator equipment.

3.Design procedures should be as simple as possible, easy to understand,and there are certain rules to be suitable for different control floors.

4.PLC has perfect function of power cut memory,to ensure there is a reliable working condition in all cases.

5.The processing control circuit is as simple as possible.

6.To meet the advanced nature of PLC control.
