Handrail

The handrail is made of high quality rubber and is completely close without any joint on the surface. Its outer layer is woven by fiber and steel wire and covered with nice rubber. The handrail is installed on the balustrade. It runs faster 0 to 2% than the steps in order that the passengers can hold the handrail.

1.3.11 Inner decking and outer decking

The inner decking is installed between the skirt panel and the balustrade interior, and the outer decking between the skirt panel and the exterior paneling. They are made of striped stainless steel cover plates and easy to be disassembled.

1.3.12 Electric control

The electric control adopts PLC control method in DIAO SME escalator, which is consisted of two control boxes. One is a power box that is fitted in the driving station, and the other is a PLC control box that is fitted in the return station. Considering safety and convenience of maintenances, there are an inspection socket and an emergency stopping button on both control boxes. The control box can be taken out when the front tread is open.

1.4 Safety protection:

1.4.1 Protection devices for ruptured or extended step chains

The protection devices are fitted on the return station. In the case of rupture or extension of any piece of traction chain, the safety devices take effect. The power is cut and the steps stop at the same time. And the corresponding failure number is also displayed.

1.4.2 Safety protection device for sagging steps

In case the steps are sagging, the steps pallet or the steps shaft touch a stick, and then the stick turns on the switch to cut the machine power and the steps stop. At the same time, the corresponding failure number is also displayed.

1.4.3 Safety switch for clearance between steps and skirt panel

There are two safety switches on each horizontal part of an escalator respectively. The skirt panel panel is deformed because of extrusion when it collides with steps or when foreign bodies are trapped in the clearance between steps and skirt panel. And this make the safety switches take effect. The machine power is cut and the steps stop. At the same time, the corresponding failure number is also displayed.

1.4.4 Safety protection device for combs

There are two safety switches behind each combs respectively, one is on the right and another on the left. The combs move backward when a single push force of 750N is exerted on the combs, which makes the safety switches take effect. Then the machine power is cut and the steps stop. At the same time, the corresponding failure number is also displayed.

1.4.5 Protection device for fingers

There are safety protection devices at each of the four entrances. In the case of foreign bodies or passengers’ fingers trapped at the entrances, the safety devices take effect. The machine power is cut and the steps stop. At the same time, the corresponding failure number is also displayed.

1.4.6 Protection device for driving chain

In case of rupture or extension of the driving chain, the safety devices take effect. The machine power is cut and the steps stop. At the same time, the number is also displayed corresponding to this failure.

1.4.7 Monitoring for the speed of escalator.

An electronic tachogenerator is fitted under the output chain wheel of the drive machine. If the speed inspected by the equipment is under 80% or over 110% of the rated speed, the controller sends a signal to stop the machine.

1.4.8 Step lighting

A green lighting bulb is fitted under each horizontal part of steps of an escalator, and then passengers are able to see the edge of steps clearly. It can prevent a danger.

1.4.9 Failure display

Considering the convenience of maintenance,DIAO SME series of escalators are equipped with a failure display, which is fitted on the down part of the controller or on the skirt panel. In case any malfunction of the escalator occurs, the inspector can consult the failure code table according to the information supplied by the display and confirm what is wrong with the escalator. You can get the details about the failure code table from “Electric Maintenance Instruction.”

1.4.10 Lubricating device

The device ensures lubricating driving chains and step chains of escalator. You can choose automatic or manual way to lubricate.
