Different types of escalator handrail joints

The different types of handrail joints for escalator handrails include the following:
1. Hot Vulcanization Joint:
o Features: This joint is created by heating and pressing the two ends of the handrail together through a vulcanization process. The procedure is typically carried out under high temperature and pressure to ensure the strength and durability of the joint.
o Advantages: The joint is smooth and firm, with almost no visible seam, making it highly durable and suitable for long-term use.
o Disadvantages: It requires specialized equipment and skilled technicians, making the process complex and time-consuming for repairs.
2. Mechanical Joint:
o Features: This joint is formed by using mechanical devices to connect the two ends of the handrail, usually with special clamps or fasteners.
o Advantages: It is easy to install and repair, requiring no complex equipment, making it ideal for quick on-site replacement or repair.
o Disadvantages: There may be a visible seam at the joint, potentially affecting the handrail’s smoothness and aesthetics. Durability is relatively lower compared to other methods.
3. Cold Adhesive Joint:
o Features: This type of joint uses a specific adhesive to bond the two ends of the handrail together, without the need for heating or vulcanization.
o Advantages: It is relatively simple to operate and does not require high-temperature equipment, making it suitable for small repairs or quick fixes.
o Disadvantages: The bond strength and durability are lower, and it may be more affected by environmental factors like temperature and humidity.
4. Pre-Made Joint:
o Features: The handrail is pre-manufactured with joints in place, so installation involves simply fitting the pre-made joint together.
o Advantages: It allows for quick and easy installation, reducing on-site processing time and complexity.
o Disadvantages: Precise matching is required during installation, and errors could result in an unstable or insecure joint.
Each type of handrail joint is suited for different scenarios based on factors such as the escalator’s operating environment, usage frequency, and ease of maintenance.
