Elevator Expansion Bolts

short description:

Expansion Bolts are special threaded connections used to fasten pipe supports, hangers, supports, or equipment to walls, floors, and posts.

The expansion bolt comprises a countersunk head bolt, an expansion pipe, a flat washer, a spring gasket and a hexagon nut.

When in use, the impact drill (hammer) is used to drill a hole of corresponding size on the fixed body, and then the bolt and the expansion pipe are inserted into the hole.

Elevator Expansion Bolts are fastening devices used to secure elevator equipment and components. These bolts are designed to provide a secure and permanent connection in concrete or masonry applications. They are commonly used in the installation of elevator equipment, such as guide rails, safety gears, sheaves, and hoist ropes.


1.The primary advantage of using Elevator Expansion Bolts is that they provide a strong, reliable connection that cannot be easily loosened over time. This makes them an ideal choice for use in high-stress and high-vibration environments, such as those found in elevators. Unlike traditional mechanical fasteners, elevator expansion bolts expand as they are tightened, filling the entire drilled hole and creating a tight and secure connection.

2.Another advantage of Elevator Expansion Bolts is that they are relatively easy to install, even in hard-to-reach areas. This reduces the time and effort required to complete an installation, which can result in significant cost savings. Furthermore, because they do not rely on threads to secure the fastener in place, they can be used in holes that are slightly undersized, which is useful in applications where the exact size of the drilled hole may vary.

Overall, Elevator Expansion Bolts offer a high-strength, reliable fastening solution that is well-suited for use in elevators and other high-stress, high-vibration applications. They are easy to install, cost-effective, and provide a long-lasting connection that will help ensure the safety and reliability of your elevator equipment.
