The job starts with a site survey, not a motor choice. The installer checks gate weight, hinge and post condition, driveway slope, available power supply, and the arc or run needed for the gate to open fully. For swing gates, hinge alignment and post rigidity determine which ram or articulated arm operator suits the load. For sliding gates, the survey confirms whether a ground track or cantilever system is the right fit, a cantilever gate hangs from carriages fixed to posts beside the opening, so gravel, frost heave, and uneven surfaces cannot stop it. Steel, wrought iron, timber, and aluminium gates all behave differently under a motor, and the survey is where that is established rather than assumed.
Once the operator and gate type are confirmed, the installer fits the motor, control panel, and power supply wiring to BS 7671 18th Edition standards. The control panel governs open and close timing, obstacle detection sensitivity, and the relay output that triggers an intercom or app-based access system. Cat5 or two-core cabling routes the signal from a GSM or WiFi visitor panel to the control panel, with wireless options available where burying cable is impractical. Post foundations and cable ducting are completed as part of the same visit where groundwork is needed, so there is no second mobilisation cost.
The final stage is safety sensor setup and a full open/close test. Safety edges are fitted to the leading and closing edges of the gate leaf, and photocells are positioned to detect a person or vehicle in the gate’s path. The installer runs repeated open and close cycles, checks that the gate stops and reverses on contact with the safety edge, and confirms that closing force stays within the limits set by the Supply of Machinery Safety Regulations. Only once the gate passes this test is the job signed off. An older gate can often be retained if the structure is sound, the survey is where post rigidity, hinge wear, and overall balance are assessed to confirm whether the existing gate is suitable for a motor.
