Can motor size be selected from gate weight alone?

No. Gate weight is only one input. Rolling resistance, gate length, track and wheel condition, duty cycle, wind exposure, slope and the operator manufacturer's limits must also be checked.

Can an existing sliding gate be automated?

Often yes, but the gate should first move smoothly by hand and have suitable guides, end stops, wheels, track, run-back space and structural mounting points. Mechanical faults should be corrected before an operator is fitted.

What happens during a power cut?

A suitable installation needs an accessible manual-release procedure, with user training at handover. Battery or UPS backup can be considered where continued automatic operation is required and the selected equipment supports it.

Are photocells enough to make an automatic gate safe?

Not by themselves. Safety depends on the complete site-specific risk assessment, gate geometry, guards, control logic, force settings, protective devices, installation and testing. Photocells only protect the zones in which they are correctly positioned and functioning.

Sliding Gate Automation Site Survey Checklist Jaipur

The first test is mechanical: isolate any existing automation and have a competent person check that the gate travels smoothly by hand. A larger motor does not repair a bent track, worn wheels, missing end stops or unsafe geometry.

Gate, track and structure

Record whether this is a new gate, an existing manual gate or a replacement automation. Check that the gate is rigid, plumb and guided without excessive lateral movement. Inspect the full track for straightness, level, joints, corrosion, debris and monsoon water paths. Inspect wheels, bearings, guide rollers and brackets for wear, binding or undersizing. Confirm physical end stops and sufficient run-back space at fully open and fully closed positions. Identify trapping, crushing, shearing and drawing-in points around posts, walls, rollers and the moving leaf. Confirm a sound, drainable foundation and mounting position for the operator and rack. Record any slope, cantilever arrangement, solid infill or wind-exposed gate surface.

Dimensions, load and duty cycle

Survey field	Record on site	Why it matters
Clear opening	________ mm	Affects travel time, rack length and the required clear run-back.
Gate length / height	________ / ________ mm	Needed for geometry, wind exposure and product limits.
Estimated actual weight	________ kg · method: ________	Brochure limits are not a substitute for a defensible load estimate.
Manual push / pull test	________ N or technician observation	Reveals rolling resistance and tight spots across the full travel.
Peak openings	________ per hour	A society gate and a private villa can require very different duty capability.
Typical openings	________ per day	Supports operator, backup and preventive-maintenance planning.
Users / traffic	Cars · two-wheelers · pedestrians · pets	Changes the access workflow and safety-zone design.

Do not size from kilograms alone. The final operator must be checked against the manufacturer’s current limits and instructions, considering actual rolling resistance, gate length, duty cycle, environmental exposure and safety configuration.

Site-specific safety survey

Map every normal and foreseeable path for vehicles, pedestrians, children, pets and service staff. Mark opening-side and closing-side risk zones; do not assess only the driveway beam line. Specify protective devices for the actual risks: photocells, safety edges, guards and warning devices as applicable. Prevent reach-through or access to exposed rack, rollers and other hazardous moving parts. Decide automatic-close, semi-automatic or hold-open behaviour from the traffic workflow and risk assessment. Define obstacle response and test it through representative opening and closing scenarios. Keep controls where the operator can observe the gate when site conditions require it. Plan emergency access so the release can be used safely without entering a hazardous movement zone.

Manufacturer instructions show why photocell position and function matter: different sensor zones can act during closing, opening or both. The complete risk assessment determines which devices are required.

Power, earthing and outdoor work

Confirm supply voltage, available circuit, isolation, protection and cable route with the electrical professional. Verify earthing and surge-protection requirements for the selected operator and site installation. Keep control, sensor, intercom and network routes coordinated with power and accessible for service. Provide drainage and suitable outdoor enclosures; avoid low cable joints or ducts that collect water. Record the behaviour required during an outage: manual release, UPS, supported battery backup or guard procedure. Confirm that the manual-release key or tool will remain accessible to authorised users. Plan a flasher, gate-open indication or audible warning where the site risk assessment calls for it. Photograph conduit exits, foundation dimensions and cable routes before they are covered.

Access control and daily workflow

List who needs entry: family, guards, residents, staff, vendors, deliveries and emergency responders. Choose the required methods: remotes, keypad, RFID, guard button, intercom, mobile app or vehicle recognition. Define temporary and revocable access instead of sharing one permanent credential. Confirm what works locally when internet, cloud service, app or mobile signal is unavailable. Decide whether a pedestrian gate should be separate from the motorised vehicle gate. Plan exit operation, visitor verification, delivery handling and after-hours access. Document admin ownership, credential deletion and the process when staff or residents change. Coordinate compatible CCTV and video-intercom views without making them the only safety system.

Commissioning and handover record

Test repeated full open/close cycles and record limits, unusual noise, vibration and travel time. Test every safety device in the opening and closing scenarios for which it was designed. Verify manual release and restoration with power isolated, following the selected operator instructions. Test outage, backup and internet-down behaviour; record what continues and what does not. Give the owner product manuals, wiring/as-built drawing, settings record, keys, warranty and service contact. Train authorised users on normal control, emergencies, manual operation and fault reporting. Record installer, operator model/serial, commissioning date and protective devices fitted. Agree an inspection and maintenance schedule based on usage, environment and manufacturer instructions.
