Escalator handrail belt tensioning chain device tensioning chain handrail belt sprocket set 9 rounds

The functions are as follows:
Provide tension: Keep the handrail belt at an appropriate tension. Through the cooperation of 9 wheels and chains, the handrail belt can be evenly tensioned to ensure that the handrail belt will not relax during operation, so as to keep synchronous movement with the steps, provide passengers with stable handrail support, and ensure the safety of riding the escalator.
Guiding function: The layout of the 9 wheels and the connection method of the chain provide precise guidance for the handrail belt, limit the lateral movement of the handrail belt during operation, so that it can only move along the predetermined path, prevent the handrail belt from running off, twisting, etc., and ensure the smoothness and reliability of the handrail belt operation.
Buffering and shock absorption: When the escalator is running, it can absorb and buffer the vibration and impact force generated by the handrail belt due to various reasons. For example, when the escalator starts, stops, or encounters a passenger suddenly applying a large force, the 9 wheels of the compression chain can alleviate the impact of these forces on the handrail belt through its own elastic deformation and the rotation of the wheels, reduce the wear of the handrail belt, extend its service life, and also improve the comfort of passengers when using the handrail belt.
Adjust the tightness: The tightness can be adjusted according to the actual operation of the handrail. As the handrail is used, it may stretch or relax. By adjusting the position of the 9-wheel compression chain or the length of the chain, the handrail can be restored to the appropriate tension state to ensure that the handrail can always work properly.
Protect the handrail: Avoid direct friction or collision between the handrail and other components. The system formed by the 9 wheels and the chain isolates the handrail from the surrounding structure, reducing the possibility of external interference and damage to the handrail, protecting the surface quality and internal structure of the handrail, and improving its safety and durability.
