EscalatorChain escalator chain Types
The escalator chain is the mechanical part that allows the escalator to move from one floor to another. This chain is made of small pitch conveyor chains that carry materials directly on a jig installed on the attachment. The type of materials conveyed by the escalator chain will vary depending on its application. There are many different types of attachments for escalators. A modern standard escalator chain has several advantages, including fast delivery and top-notch economy.
Escalator chains have two types: step chains and roller chains. Step chains are designed for greater wear resistance because the pin diameter is larger than a regular chain. Chain links and steps are strictly coordinated, but a lubrication-free or low-noise chain is preferred for quiet environments. While these types of escalators do require regular lubrication, they are less noisy than their counterparts. If your escalator is making a lot of noise, you should consider a low-noise escalator.
The guide wheel is made of polymer. The polymer has a circumferential slot and radially extending side surfaces. The wheels 33 and the escalator step are constrained laterally by the guide rail 36. The escalator chain, on the other hand, is not constrained laterally by wheels. This is because the rollers remain orthogonal to the length of the chain. The escalator chain is not constrained laterally by wheels, but by the lateral force generated by the escalator when the machine is in use.
Escalator chain installation differs from country to country. Step chains are usually installed every 400 mm. They come in different pitches and tensile strength, ranging from six to thirty tons. Most escalator chains are nine or fifteen tons in strength. The pitch of escalator chains should be small enough to minimize the chordal action and allow smooth operation. There are many different types of escalator chains.
If the escalator chain does not move freely, it can activate the safety switch in the programmable logic controller, causing the escalator to stop abruptly. In such cases, the passengers can lose their balance or fall over due to the abrupt stop. If the chain is not loose, you should first loosen the four screws on the base of the motor. The stiffness and looseness of the chain should be determined by the stiffness of the chain.
The Renolube Escalator Chain was developed after extensive prototype testing to meet the needs of the escalator industry. This synthetic lubricant helps reduce the cost of life cycle and maintenance. It also helps reduce noise levels and provides a cleaner environment. Further, it reduces the risk of fire by reducing the need for lubrication. This product is a highly effective lubricant. Its unique properties make it a preferred choice for maintenance of escalator equipment.

A guide rail is the other important part of an escalator. Its purpose is to interconnect two chains. Its axes are orthogonal to the chains. The sleeves also contain pins for interconnection. The guide rails and the sleeves can be found at the bottom of escalator systems. They are designed to allow sliding movement between the convex and concave surfaces. They replace pins that are present in the sleeve.
