Product Description

Elevator railing expansion screws, also fondly known as elevator geckos, are a specialized threaded connector meticulously crafted for the elevator installation accessories industry. These screws are unique due to their design precision and functionality. Here is an in-depth overview of these indispensable components designed for elevator railings:

1, Definition and Composition

Expansion screws, true to their name, achieve a robust fixing effect by exploiting the frictional force generated through expansion. The expansion screw tailored for elevator railings is a composite of countersunk bolts, durable expansion tubes, flat washers, resilient spring washers, and robust hex nuts. Once inserted into a pre-drilled hole, the expansion tube widens, creating a snug fit against the hole wall, thus securely anchoring the elevator railing and associated components.

2, Characteristics and Applications

• Features:

Seismic resistance and durability: With a reliable post-expansion functionality, these expansion screws for elevator railings are engineered to endure significant vibrations and loads, guaranteeing the unwavering stability and safety of elevator railings.

• Quick assembly: Designed for swift and straightforward installation, these screws considerably cut down on installation time and labor expenses, offering efficiency and cost-effectiveness.

• Strong fastening force: Equipped with thickened sleeves and enlarged flat pads, these screws boast an impressive fastening force, making them ideal for heavy-duty applications.

• Purpose: Primarily utilized for securing elevator tracks, brackets, racks, and railings, these screws play a crucial role in maintaining the stability and safety of the entire elevator system.

3, Specifications and Selection

Elevator railing expansion screws are available in a variety of specifications, including M8, M10, M12, among others. The selection of specific specifications should align with the installation environment and usage demands. When making a choice, consider the following key points:

• Substrate type: Designed to work with substrates like concrete and dense natural stone, ensuring a firm and reliable fixation to the substrate surface.

• Tension value: Opt for expansion screws with suitable tension values that match the installation environment and operational needs, ensuring a secure and reliable connection.

Product quality: Prioritize reputable brands and high-quality products to guarantee the superior performance and longevity of the expansion screws.

4, Installation precautions

During the installation of expansion screws for elevator railings, it's vital to observe the following precautions:

Drilling requirements: Utilize a correctly sized drill bit to create the hole, ensuring the depth and diameter are suitable for the expansion screw. The drilling must be perpendicular to the substrate surface to prevent tilting or misalignment.

Clean up debris in the hole: Prior to installing the expansion screw, ensure the removal of dust, powder, or debris in the hole to enable smooth expansion and a tight fit against the hole wall.

Tightening force: Employ tools like wrenches with caution, applying moderate force to tighten expansion screws, thus avoiding excessive force that might lead to screw breakage or substrate damage.

5, Maintenance and Inspection

Regular maintenance and inspections are paramount to ensuring the stability and safety of expansion screws on elevator railings. Inspections should include checks for loose screws and any deformation or damage to the expansion tube. Any anomalies must be swiftly addressed with repairs or replacements.

In conclusion, elevator railing expansion screws are vital components of elevator installation accessories, celebrated for their seismic resistance, durability, and speedy assembly. When selecting and installing these screws, it is crucial to thoroughly evaluate the specific conditions to assure a dependable connection.
