Elevator Expansion Bolts

Elevator Expansion Bolt is a high performance fastener designed for elevator installation and fixing, which provides strong clamping force through a unique expansion mechanism to ensure the stability and safety of elevator equipment. The design of elevator expansion bolts is based on the expansion anchor fixing principle. This involves inserting the bolt into a pre-drilled hole and then utilizing a tapered sleeve or other form of expansion mechanism to create a strong connection by squeezing the material around the bolt (e.g., concrete) to create friction during the tightening process. This mechanism not only provides strong tensile strength, but also effectively prevents loosening, even when subjected to prolonged vibration and shock loads. Elevator expansion bolts are widely used in the fixing of elevator guide rails, cabs and other key components. They are able to withstand enormous weight and dynamic loads, ensuring smooth and safe elevator operation.

1,Use an impact drill to drill a corresponding hole in the wall or concrete cornerstone.

2,Fit the expansion bolt and expansion pipe into the hole.

3,Fit the large washer and spring washer in turn, and tighten the hexagonal nut by screwing it in until it is connected as one piece to ensure that it is fastened to the concrete wall or cornerstone.‌
