JIEFENG Escalator Chain

JIEFENG Escalator Chain

Escalators are a well-known method of conveying passengers from one elevation to another. They typically have a frame with a pair of truss sections on each end.

Each truss section has two end sections parallel to each other, connected by an inclined midsection. Each truss also has a bottom landing. The top and bottom landings house curved sections of track, as well as motor and gear assemblies.


Escalators see a lot of traffic, and they need to be maintained well to ensure safety. JIEFENG has developed an escalator chain that is extremely wear resistant and offers stable and predictable wear rates. This provides peace of mind that the escalator will last for many years, which helps minimize maintenance costs and life cycle costs.

The escalator chain has several safety features that prevent accidents and keep passengers safe. For example, there are devices that detect and stop steps if a shoe or other object is trapped between the step guards and the steps. There are also devices that monitor phase interruption or reverse phase and stop the escalator if there is an abnormality in the escalator speed.

These devices can be installed on the escalator newel or as stand-alone pedestals. They will ground the handrails and drain away that static charge that can sometimes lead to a shock for riders.

They also monitor comb plate movement and prevent escalator crashes by shutting off the motor when a comb plate moves horizontally or vertically, or if there is an entrapment of foreign objects between the comb plate and step guards.

Another device that prevents escalator or moving walk accidents is a brake lining device, which prevents the escalator drive motors from starting while the escalator has been disconnected from its power supply. It also has an emergency stop button that stops the escalator in case of an electrical failure or when any safety device is activated.

This safety feature can be used on the escalator newel, as a standalone pedestal or as an addition to the existing handrail safety devices. It is an excellent way to eliminate the shock experience often associated with older escalators that do not have this type of system.

Keeping the handrails safe is crucial to passenger safety. Without this device, a handrail can be caught in the escalator moving steps or tripped on its side.

The KONE Spares Slimline Power Stop is an escalator safety station that sits at the top of the escalator newel. It safely ground the handrail and drains that static charge that can often lead to a shock for riders.


Escalators are mechanical systems that carry people up and down floors in a building or mall. They are designed to rise at 30 or 35 degrees from the floor, move at 0.3-0.6 metres per second (1-2 ft/s) and traverse vertical distances in excess of 18 metres (60 ft).

The steps on an escalator are connected in series and are supported on a system of tracks. At the top and bottom of the escalator, the tracks converge. This right angle forces the front and back wheels of the steps to a flat configuration, one after another, so that they can pass around a curved section of track and exit the escalator at the bottom landing.

When the steps reach a point where they are not able to continue in this flat configuration, they begin to bend. This is where the escalator chain comes in handy.

To prevent the steps from bending, the escalator chain is designed to have a small pitch. This reduces the effects of chordal action, escalator chain which can cause the steps to shake uncontrollably and make them more difficult to use.

In addition, the escalator chain is designed with a number of features that ensure smooth operation. These features include the use of high-quality materials, a robust design and a high tensile strength.

A number of safety devices are also included in the escalator chain, such as a brake mechanism that prevents passengers from falling off. The brakes can be activated by pushing the emergency stop button located on the escalator’s handrail or at floor level.

Moreover, the escalator chain is designed so that it does not slip or break, which can result in the death of a passenger. This feature is especially useful when the escalator is used in a busy area, such as a shopping mall.

The escalator chain is a vital component of the escalator, which can help transport hundreds of people per hour in an efficient manner. However, it must be installed in the right place. It should be positioned near the main routes of the infrastructural building to ensure that it doesn’t interfere with traffic flow.


An escalator chain is an essential part of the escalator system. It consists of an array of steps that move about like a conveyer belt, connecting to a large metal structure called a truss.

The escalator chain is made of steel links with hardened pins that engage drive sprockets to connect the adjacent steps. These chains are typically greased to help prevent wear and maintain a smooth ride for passengers.

When the escalator chain breaks, it causes the escalator to stop automatically. This is a serious safety concern because it can lead to an abrupt stop and a loss of balance for passengers.

To prevent this from happening, an escalator chain needs to be replaced regularly. The escalator manufacturer has a solid maintenance program in place that helps keep the chain in good condition, and it’s important to follow those rules when replacing the chain.

Another important factor to consider when replacing the escalator chain is the type of chain being used. Greased chains tend to wear quickly and are susceptible to random failure, while a non-greased escalator chain can last for decades with minimal maintenance.

If you’re considering installing a non-greased chain on your escalator, it’s best to check with the manufacturer first and ask for a quote. A non-greased escalator is more expensive to install, but it will save you money in the long run.

Escalator chains are also a complicated piece of equipment to replace, and you’ll need the right tools to get the job done properly. That’s why it’s crucial to hire escalator chain a qualified escalator company that can handle any maintenance task you need done.

It’s a good idea to have an escalator service and safety audit performed by a third party. This will make sure that all aspects of your maintenance service are completed correctly and in line with the contract you signed.

An escalator service and safety audit will also give you a full view of the performance of your elevator provider and how it complies with all safety regulations. The results of the escalator service and safety audit will help you make informed decisions about your future maintenance needs.


Escalators are a type of moving walkway, mainly used in department stores and airports. They typically rise at an angle of 30 or 35 degrees and move at 0.3-0.6 metres per second (1-2 ft/s).

They generally have single-piece aluminum or stainless steel steps that run on a system of tracks in a continuous loop. Each step can accommodate a large number of passengers and moves at relatively high speeds, so noise levels are often very high.

An escalator chain is a key element in an escalator’s driving mechanism and consists of a step chain, drive sprocket and axle. It also provides an effective means of propelling the steps and handrails in a manner that is safe and efficient.

There are a variety of different types of chains available for escalators, including low-noise and low-maintenance. However, all escalator chains are subject to the same basic design considerations: The chain must be able to withstand a certain amount of pressure and stretch.

In the case of a step chain, this means that the pins on which the steps are mounted must be large enough to withstand a substantial load from the step and its passengers. In addition, the step must be able to withstand a considerable amount of wear and tear in use.

Therefore, it is important to have a chain that can withstand these high stress levels without causing any damage. As a result, many manufacturers develop chain solutions to meet specific requirements.

One such solution is the CSB-PEC(r) self-lubricating escalator rotary chain, which adapts a new patented design of self-lubricating bearings. These bearings are made of EPB15 engineering plastics that have excellent resistance to dust, so they can operate normally for a long time in harsh environments.

This solution reduces the number of abrasive particles that enter the bearings, and the rolling bearings do not need to be lubricated as frequently. This results in long-term stable operation for the escalator.

As a leading manufacturer of chains for escalators and moving walkways, KettenWulf understands that the needs of customers are increasing. That is why they are constantly developing new solutions in the areas of safety, design and maintenance.
