Why only 2 people can stand side by side on the escalator step?

Baesd on the problem of escalator’s Bearing capacitybalance, the best circumstance is to stand only a person, but considering somepeople can compare anxious, so for now the escalator can stand two people sideby side, one people stand on the escalator step, and aonther can waking on the escalator step.

The escalator will be be easy to damage, and it will reduced the using life if lots of people Standing side by side on the escalator step, and it’s not safe.

By the way according to GB 16899-2011 Safety specification for the manufacture and installation of escalators and moving sidewalks

5.3.2.1 general rule

Nominal width of escalators and moving walkways z1 must more than 0.58meter，and less than 1.10meter。For automatic sidewalks with a tilt Angle of no more than 6 degrees，the width can be 1.65meter。

In addition, when the width of escalators and moving walkways is more than 1meter, the conveying capacity will not be increased, because users need to hold the handrail belt, and the moving walkway is widened in principle for trolleys.

How to replace the escalator step roller

1,Using the circlip plier to take off the jump ring(escalator ring)

2,Then using Three-Jaw Puller to take offf the old escalator stop roller

3, Then add the new escalator step roller(pls note, put the old roller on the top of the new escalator roller), using hammer strike the old roller

4, Add the jump ring again when the new escalator step roller have been installation complete

5, Test it, and the replacement have been finished if the test is good.

colorful escalator handrail

This article will help you know colorful escalator handrails.

In normal there have 8 colors on the market, and the colors as follows:

We have 9 kinds of colors, more than 1 color, and this color is pink,and our colors as follows:

The colorful escalator handrail still have C type and V type, today we will show these kinds of colorful escalator handrails.

1, Let's see the C type colorful escalator handrail first;

KR007 Green color

18 pcs stainless steel wire ropes as photos.

7 strands for 1 pcs stainless steel wire rope

2, V type escalator handrail

KR003 blue color colorful escalator handrail

As C type, still 7 strands for 1 pcs stainless wire rope.

But V type have 21 pcs stainless wire ropes.

Escalator friction wheel

Escalatorfriction wheels is a part of escalator, and it’s quick-wear part, this article will help you know escalator fricion wheel.

Technology

Escalatorfriction wheels consist of an elastomer coating and a metal body.

The elastomer coating is like the escalator handrail’s coating.

The friction lining is permanently joined to the metal part.

The polychloroprene based elastomer mixture used has a hardness of 80 ± 5 Shore A. It is wear resistant and largely oil resistant, by the way Escalator firction wheel also using ellow paint to rust-proof.

The metal body is made from standard free cutting  steel 9 S 20 K. Centerings are provided for subsequent machining.

The metal body is wider on one side than the friction lining for easy rolling gear mounting.

Installation

The axles of the driving and driven shafts must be aligned parallel. Radial runout of the wheels must be avoided.

Where rolling gears are mounted side by side, the shaft must have sufficient rigidity.

For applications requiring a virtually vibration-free drive and high concentricity – and rolling gears mounted in pairs – the rolling gears must ground after mounting.

Worn rolling gears must be replaced in pairs.

In this way,the high production tolerances are compensated and rolling gears mounted in pairs are subjected to uniform load.

matters need attention

When machining the metal parts, the temperature of the metal should not exceed 100 °C. When grinding and turning, the temperature of the friction lining should not exceed 70 °C, briefly 80 °C.

Reciprocating longitudinal grinding produces a smooth surface.

Face grinding must be avoided.

Exerting low pressure prevents excessive heating. The elastomer coating smears under excessive pressure.

If the surface is smeary, interrupt grinding and allow the elastomer coating to cool down completely.

Apply talcum powder to the surface.

Subsequently grind clean exerting low pressure.

In normal the thickness of escalator friction wheel is 5-7mm, and i can working over more than 12months, our escalator friction wheel's thickness can be 9-10mm, so ours can working over more than 24months.
