Automatic and manual cantilevered sliding gates
Cantilever gates are a slightly more sophisticated and have more advantages over other gate systems

A cantilevered sliding gate or cantilever gate operates by using an extended section of the gate to counterbalance the actual gate which spans the road access. So in effect, the cantilever gate is suspended and therefore doesn’t require a track below it to run along.

We classify our Pro-glide sliding gates into three series.  The series of Pro-glide 5 sliding gates will work just as smoothly and efficiently as series Pro-glide 30 gates.  The differences between series 5, 20 and 30 are about aesthetic design, added features and the level of bespoke design and construction.


What is a cantilever gate and how does it work?


The cantilever gate is similar to the slide gate, but does not use rollers that slide along the ground to support it. Instead, the cantilever gate is supported from rails that run along the inside of the fence structure. This gate gets its name from the fact that the gate “cantilevers” (hangs over) the gate opening. Cantilever gates need to be much wider than slide gates in order to provide a section along the fence structure where the gate is supported. This section is called a “counterbalance” and is usually at least 1/2 the width of the gate opening itself

Cantilever gates work by being suspended across from the counterbalance to the gate opening , with no rollers running along the ground to provide friction or to become obstructed. Because of this feature, cantilever gates are considered to be much more reliable than slide gates, and are commonly used for heavy-duty and industrial gate applications.

One downside to using cantilever gates is the additional width required to accommodate the counterbalance. This can be a problem at sites that have limited space available beside the gate.

The process of deciding whether or not a cantilever gate is more suitable should start by reviewing the job it has to do and the site conditions.

  1. The width of the access point needs to be determined. If it is less than around 20-25m and assuming there is space on either side of the access for the run-back of double gates, then a cantilevered option will normally be suitable. Individual cantilever gates can be made to span an entrance up to 15m;
  2. Sufficient space adjacent to the gate to allow for the counterbalance section of the gate to run into, along with the gate leaf itself of course. As a guide, the counterbalance section of the cantilever gates will add about 40% to the total length of the gate.
  3. Uneven Ground Surface or Sloping – The ground surface the cantilever sliding gates operate over does not need to be exactly level because the gates never actually touch it. So if both types of sliding gates are being considered, it’s worth weighing up the additional cost that preparing the ground to take a track would be, versus limited ground preparation for the cantilever gates option. See case study.
  4. Less Ground Work – Most importantly, the type of the site the access protects and the extent to which it gets extreme weather in the winter. The point here is that if the site is prone to debris – e.g. mud and stones – and these are being carried on vehicle tyres, then a cantilever gate is far more suitable because there’s simply no track in the ground to keep clear. Equally, the same applies to snow and ice on the ground – a cantilever sliding gate will largely be unaffected by such conditions.
  5. Quieter Operation – A further consideration might be noise, and a cantilever gate is certainly quieter in operation than tracked gates. So this might be a factor if, for example, the access to the site was very close to a residential area.
