Like the V Groove slide gate, the industrial cantilever slide gate opens by sliding sideways to make way for incoming and outgoing vehicles. Unlike other industrial slide gate designs, the 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 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).
The Heavy Duty swing gate is more like a door in that it opens at one end and typically extends 90 degrees when fully open (swing options are 90 degrees each way or 180 degrees one way). The gate can swing inside or out, and it can have one or two leaves. However, the swing gate can be hazardous at unmanned, unmarked entrances because of its ability to swing outward.
