Bring ultimate power, extended reach, and mechanical sophistication to large entranceways with the Fadini COMBI 740 (K740.4L) Underground Double Gate Automation Kit. This top-tier model represents the absolute peak of the Combi 740 series, combining an extended 175° wide-angle shaft rotation with integrated adjustable hydraulic braking (slowdown) in both directions. Built to cleanly handle large residential and heavy commercial double swing gates up to 4 meters wide per leaf (or up to 700kg for shorter leaves), this kit completely conceals its heavy-duty mechanics underground within robust galvanized steel foundation boxes.
Featuring bidirectional double hydraulic locking, it firmly anchors your gates when fully opened and closed, delivering pristine architectural symmetry alongside uncompromising perimeter security.
Premium Hydraulic Braking: Actively cushions the final 40cm of the gate’s travel during both opening and closing cycles, preventing slam, protecting hinges, and ensuring silent operation.
Extended 175° Wide Rotation: Specifically engineered for deep-set pillars, angled driveways, or unique entryways where gates must fold almost flat against boundary walls.
Uprated 4-Metre Leaf Capacity: Specially internal-valved and tuned to manage the substantial momentum and wind leverage of wide timber or wrought iron gates.
Subterranean Double Hydraulic Locking: Internal hydraulic valves lock the gate leaves solidly at both travel extremes, eliminating the need for an electric lock on standard setups.
Automating wide gate leaves presents a distinct engineering challenge: the sheer momentum generated at the end of a 4-meter swing can easily stress hinges and wear out standard motors. The Fadini COMBI 740 K740.4L system directly solves this by integrating adjustable internal flow-braking into its heavy-duty hydraulic jack cylinder. As the gate reaches the tail end of its travel, the hydraulic fluid is throttled, smoothly deceleration-pacing the leaf to a whisper-quiet close.
Because everything is self-lubricating and tightly sealed in an IP67 enclosure, the motor pump operates seamlessly entirely out of sight under your driveway. Backed by the industry-standard Elpro 27 Control Board, this kit gives installers complete micro-processor command over delay times, safety photocopy margins, and precise closing speeds, making it the premier choice for busy multi-user access ways or high-end private estates.
Zero Footprint, Maximum Protection: Keeps the pristine face of bespoke timber or architectural metal gates completely uncluttered by unsightly external surface rams.
Adjustable Thrust By-Pass Valves: Features dual mechanical by-pass valves that allow precision tuning of anti-crush safety limits to meet stringent European safety standards.
Corrosion-Resistant Foundation Housing: Housed inside a 3mm thick, electrolytically galvanized steel foundation box built to withstand permanent contact with damp earth and winter frost.
Ergonomic Manual Override: Includes left- and right-handed pressed steel emergency release brackets with custom ergonomic spanners for effortless manual disengagement during site power outages.
2x Fadini COMBI 740 Hydraulic Operators: (1x Left-Handed, 1x Right-Handed, 175° Rotation, Double Locking & Internal Braking).
2x Zinc-Coated Heavy-Gauge Steel Enclosures: Protective foundational underground boxes with drive lids.
1x Elpro 27 Advanced Control Unit: Multi-functional, micro-processor logic command board.
1x VIX 53/2 R Radio Receiver Module: High-security plug-in frequency card (868.19MHz).
2x VIX 53/4 TR Rolling-Code Remote Transmitters: Rugged multi-channel pocket fobs.
1x Tuned Rod Radio Antenna / Aerial: Enhances remote command range across complex masonry walls.
1x Pair of Safety Photocells: Active infrared beams to actively prevent gate closure on crossing vehicles or pedestrians.

Pro Tip: Because the K740.4L is engineered to manage long gate spans, installers must strictly adhere to the Fadini weight-to-width ratio chart to protect internal hydraulic valves from structural overload.
The Structural Law: While the maximum raw lifting limit of the Combi 740 jack is 700kg, this weight capacity only applies to narrow gate leaves up to 1.0 meter wide. As the leverage length increases, the allowable weight decreases to counter momentum. For a full-width 4.0-meter gate leaf, your maximum safe weight limit is 250kg per leaf. If your 4m gate exceeds this threshold due to heavy structural cladding or solid wood boarding, you must transition up to the industrial Fadini COMBI 787 series. Always install a physical center gate stop for 4m leaves to give the double hydraulic locks a rigid surface to press against in high crosswinds!
