Detailed Explanation of Escalator Ladder Path System

‌The Escalator adder path system is the core part of the escalator, which consists of pedals/steps, comb plates, guide rails and chains.

The pedals are where passengers stand and walk, and the comb plates are used to ensure the safety of passengers when entering and exiting the escalator. The guide rails provide support and guidance for the pedals to ensure that they move along the predetermined trajectory. The chain is responsible for transmitting power and driving the operation of the ladder path system.

‌●Pedals/steps:

The step system is the main part of the escalator to transport passengers. It includes key components such as steps, drive mainframe, main drive shaft and step chain. The drive mainframe, as the power source, transmits power to the main drive shaft through the main drive chain. The step chain drives the steps to circulate under the drive of the main drive shaft. The tensioning device of the step chain keeps the step chain in a tensioned state to ensure the smooth operation of the steps.

‌●Guide rails:

The guide rail system provides support and guidance for the movement of the steps to ensure that they run smoothly along the predetermined path. The guide rail system includes multiple components such as working guide rails and return guide rails, which constitute the ladder path of the escalator. The design and installation accuracy of the guide rail directly affect the running stability of the escalator and the comfort of passengers.

‌●Handrail system

The handrail system provides passengers with moving handrails that are synchronized with the steps to ensure the comfort of riding. The system includes components such as handrails, drive devices and guide rails, which together constitute a complete handrail conveying system. The movement of the handrail is synchronized with the steps, providing passengers with a stable grip point and increasing the safety of riding.

‌●Working principle

The working principle of the escalator relies on a traction main engine, which drives the steps or pedals to move in a cycle through a drive chain. Specifically, the drive main engine, as a power source, transmits power to the main drive shaft through the main drive chain, and the step chain drives the steps to move upward or downward in a cycle under the drive of the main drive shaft. The tensioning device of the step chain keeps the step chain in a tensioned state to ensure the smooth operation of the steps.
