Escalator Handrail Belt

1. The tension of the handrail is too tight or too loose, and the guide strip is biased.
2. The interface of the guiding device is not smooth, and there are also cases where the entire guiding device is not on the same horizontal line.
3. The friction force of the handrail drive wheel is too tight or too loose. Another issue is that the driving wheel does not rub against the edge of the handrail at the center of the handrail.
4. The entrance switch device of the handrail has friction.

Once these issues are resolved, the fever will not be as severe. The operation of the handrail relies on frictional force, and it is impossible for it not to be hot at all.
 

1. If the lip of the handrail is too large and does not meet the requirements, or if the rubber loses its performance after prolonged operation, the handrail needs to be replaced.
2. When the handrail is extended, it needs to be re tensioned as the elongation of the handrail has exceeded the allowable value.
3. Friction wheels and wings are worn and loose. Need to replace,
4. The belt roller is worn and loose.

The handrail runs around the guide rail and is guided by the guide rail. However, during the operation of the handrail, the handrail at the lower arc falls off from the guide rail. At this time, it is necessary to tighten the handrail.

1. The lip of the armrest belt is worn, which is caused by the continuous operation of the armrest belt and prolonged frictional contact.
2. If there is pilling, this phenomenon must be ruled out, as it is caused by the welding of the guide rail joint with thorns.
3. The armrest belt has a lip that is too large and swings back and forth, causing damage to the lip.

1. After the handrail stops running, the friction wheel rubs the handrail at the same position for a long time. At this point, it is most likely that the steps and handrails are not relatively stationary. Need to check the anti-skid switch.
2. Cracks appear on the surface of the friction wheel, which can easily damage the sliding layer of the handrail through friction.
3. The friction wheel and the pressure roller do not have the same acceleration, which can easily damage the surface and sliding layer of the handrail.
4. The rotating sprocket assembly is damaged. If the rotating sprocket assembly does not rotate at the arc of the handrail, it will cause long-term friction in the sliding layer, which is most likely to damage the handrail.
5. The friction coefficient of the sliding layer of the handrail itself is not high enough, which causes the friction wheel and the handrail to slip and heat up, and wear down the sliding layer.

1. The surface of the handrail is blistered, mainly due to the ineffective bonding of the wear-resistant layer, resulting in delamination and bulging. The reason is that during the production process, it was not compacted and the gas was not eliminated.
2. During the hot curing vulcanization of the handrail, the pressure is uneven, resulting in gas not being expelled.
The uneven heating surface during thermosetting vulcanization causes delamination problems.
During use, small bubbles may appear due to surface oil contamination, causing changes in the stability of rubber properties.
3. Different driving methods, armbands driven by linear systems are prone to overheating, leading to rubber delamination and foaming.

4. The structure of the handrail determines its defects. Handrail is an effective combination of rubber and curtain fabric. Due to thermosetting vulcanization, it cannot change the molecular structure of the curtain fabric, so it cannot form an inseparable whole. There must be gas hiding in the gaps. Therefore, the handrail industry around the world has not overcome the foaming factor of handrails, and every manufacturer is trying to minimize foaming.
