Slide Gate Operators
There are three common types of slide gates:
- CANTILEVER ROLLER: This is a full gate panel with a tail section that is typically half the length of the gate opening (road width), i.e. a 20′ slide gate will have a 10′ tail. There are (4) rollers to support the gate. This cantilever slide gate is not guided by rollers along a ground track. Instead, the cantilever gate is moved sideways and back via roller trucks or roller wheels mounted to gate posts.
- OVERHEAD SLIDE: Overhead slide gates use an overhead beam to support an enclosed track. A gate panel (usually aluminum for lighter weight and better appearance) is hung from the overhead track, to roll back and forth, opening and closing. An advantage of an overhead slide gate is it requires less space for the gate panel to open/slide into (no counterbalance is needed). A disadvantage is the height of an overhead beam will create an overhead restriction - usually at approximately 16 ft. high
- V-TRACK (Rolling): V-Tracks gate are normally only installed in warm weather areas where they don’t get snow. The gate rides along an inverted piece of angle fastened to the concrete like a rail. There are V-Tracked wheels that attach tot he bottom of the gate allowing it to roll back and forth. This type of gate only requires a small extended section for the operator to sit and operate the gate panel.
There are other slide gate options, but most are higher security situations and many times a custom to the project.
All slide gates are required to observe and be installed to UL 325 and ASTM F2200 standards for gate specifications and installation criteria. Failure to meet these codes exposes the near by pedestrians to injury or even death. The owner, installer, or anyone involved with the gate or its servicing can be liable in the case of an injury.
