Detailed Description
Elevator Expansion Anchor Bolts:
These are elevator expansion anchor bolts, specially used for elevator installation and fixing. Mostly made of high - strength carbon steel or alloy steel, with surface treatments like color - zinc plating for rust prevention and enhanced wear resistance. In elevator installation, they are used to firmly fix components such as elevator guide rails and car brackets on the building structure (such as concrete hoistway walls) to ensure the safe and stable operation of the elevator.
Instructions for Use:
Matching Check: Select the appropriate specification (matching the elevator component load and the structural material of the hoistway) according to the elevator installation requirements.
Pre - use Inspection: Before use, check for damage, deformation, or abnormal expansion parts on the bolt body.
Installation Requirement: Drill a hole in the hoistway structure first, then insert the elevator expansion anchor bolt, and finally tighten the nut with professional tools. Strictly follow elevator installation specifications.
Force Application: During installation, apply force evenly and in strict accordance with the torque requirements to ensure sufficient fixing force without damaging the bolt or the hoistway structure.
Maintenance: Regularly check for rust, loosening, or expansion part deformation during elevator maintenance. If any defects affecting safety are found, replace the elevator expansion anchor bolts in a timely manner.
