Cantilever Gate Systems Questions

The gate leaf must extend roughly 50% beyond the clear opening to act as a counterbalance. For a 3-metre opening, you need around 4.5 metres of total gate length, so approximately 1.5 metres of run-back behind the post line. The survey measures this before anything is specified.

Yes. Because the gate clears the ground entirely, a slope across the opening does not cause the binding or dragging that a ground track would. The survey checks that the slope does not affect post positioning or roller height.

A gate running out of alignment puts continuous strain on the roller assemblies and the motor. Left unaddressed, rollers wear unevenly, the frame distorts, and the operator can fail entirely, turning a straightforward adjustment into a full component replacement.

Generally yes. Roller assemblies, a longer gate leaf, and deeper post footings add to the cost. Where the ground is sloping, uneven, or subject to seasonal movement, that cost difference is justified by the reliability a trackless system delivers over time.

Yes. Automated gates are machinery under the Machinery Directive. Safety edges and photocells must be fitted and specified to DHF and Gate Safe standards. The installer confirms compliance at commissioning and provides the relevant documentation.

Most residential installations take one to two days once the survey is complete and materials are on order. Groundwork for post footings needs time to cure before the gate is hung, so the installer will confirm the programme at survey stage.
