Safety Information

Safety Information
Vehicular gate systems provide convenience and security. Gate systems are comprised of many
component parts. The gate operator is only one component. Each gate system is specifically designed
for an individual application. Gate operating system designers, installers and users must take into
account the possible hazards associated with each individual application.
Improperly designed, installed or maintained systems can create risks for the user as well as the
bystander. Gate systems design and installation must reduce public exposure to potential hazards.
A gate operator can create high levels of force, in its function as a component part of a gate system.
Therefore, safety features must be incorporated into every design. Specific safety features include:
Gate Edges
Guards for exposed
rollers
Screen Mesh
Important instructions follow. These instructions are intended to highlight certain safety related issues.
These instructions are not intended to be comprehensive. Because each application is unique, it is the
responsibility of the purchaser, designer, installer and end user to ensure that the total gate system is
safe for its intended use.
