Hydraulic vs electromechanical gate motors
Electromechanical 24V motors are the right choice for most residential gates: smoother, cheaper, with battery backup and inherent obstacle detection. Hydraulic operators justify their 30–60% premium on heavy leaves (250kg+), exposed windy sites and high-cycle shared entrances, where their force reserves and thermal endurance outlast everything else.
How each actually works — and what follows from it
Electromechanical: an electric motor drives a screw or gear train that pushes the leaf. Direct, efficient, precise positioning via encoders, easy battery backup at 24V. Its limits are thermal — duty cycles of 30–50% — and mechanical wear in the drivetrain under heavy leaves.
Hydraulic: the motor drives a pump; oil pressure moves a piston. Force is enormous and smoothly delivered, duty cycles reach 70–100% (continuous on some models), and hydraulic locking can hold a leaf closed without a separate lock. The trade-offs are cost, eventual seal maintenance, and less granular slow-down control on older designs.
Specification table
| Factor | Electromechanical 24V | Hydraulic |
|---|---|---|
| Leaf weight comfort zone | To ~250kg (model-dependent) | 250 – 500kg+ |
| Duty cycle | 30–50% | 70–100% |
| Wind-loaded solid leaves | Adequate with derating | Excellent — force reserves absorb gusts |
| Battery backup | Native at 24V | Rare; UPS solutions instead |
| Holding closed | Needs electric lock on larger leaves | Hydraulic lock built in (many models) |
| Service profile | Grease points, drivetrain checks | Seal & oil condition, occasional re-pressurise |
| Expected life, serviced | 10 – 15 yrs | 15 – 25 yrs |
| Installed premium | Baseline | +30 – 60% |
Real-world assignment
- Standard family entrance, aluminium or light iron pair → electromechanical 24V, with battery backup. The default for good reasons.
- Heavy ornamental iron or tall boarded steel → hydraulic rams, or hydraulic underground where aesthetics demand.
- Shared private road, 50+ cycles/day → hydraulic; electromechanical units thermally cut out on summer school-run mornings, a complaint we inherit regularly.
- Exposed ridge or open-field sites (Hog's Back, North Downs plots) → hydraulic force reserves keep leaves controlled in gusts that make electromechanical units hunt and reverse.
Brand-wise: FAAC and BFT lead hydraulics; Nice and CAME lead the 24V electromechanical field — our multi-brand position on the electric gates page exists precisely so this choice is made on the gate, not the stockroom.

Frequently asked questions
Are hydraulic gate motors worth the extra cost?
On heavy, windy or high-cycle gates, yes — they last longer and never run out of force. On a standard residential pair they're spending money on capacity you won't use.
Do hydraulic motors leak oil?
Seals eventually weep with age — a service item at 8–12 years, not a design flaw. Serviced hydraulics routinely pass 20 years; it's why they dominate commercial entrances.
Can hydraulic gates have battery backup?
Not natively in most cases; the answer is a UPS on the supply or a quality manual release regime. If power-cut operation is critical, that's a point for 24V electromechanical.
