Most sliding gate motor failures come from undersizing. Here is how we select a sliding gate motor against real leaf weight, daily cycles and site power conditions.
Start with the real gate weight, not a guess
A sliding gate motor is rated for a maximum leaf weight in ideal conditions. In real installations, rust on the track, misaligned rollers and slope all add load. We measure the gate, calculate the weight from the frame section and infill, then choose an operator with headroom above that figure.
Duty cycle decides industrial vs residential
A villa gate may open 10 times a day. A factory gate can open 300 times a day. Residential-class operators overheat under industrial duty, so for factories in Hosur and Krishnagiri we specify 100% duty-cycle operators with forced cooling.
Power quality matters in industrial belts
Voltage dips damage controllers. We recommend a stabiliser or a 24 V DC operator with battery backup wherever supply is unstable, which also keeps the gate working during a power cut.
Safety devices are not optional
Photocells, safety edges and force limitation should be commissioned and documented. Ask any supplier for the commissioning report — if there is not one, the installation is incomplete.
What a fair quote includes
Operator make and model, rack type, safety devices, control panel, cabling, civil work and the warranty terms. A price without a spec sheet is not a quote.
