COMBI 740 175 Double-Locking Braking Rh

Fadini 769789BB3SXL COMBI 740 Underground Hydraulic Swing Gate Operator - 175¡, Double-Locking, Braking, Flow Regulator, Left-Hand

The Fadini COMBI 740 769789BB3SXL is a 175¡ underground oil-hydraulic swing gate operator that combines bidirectional hydraulic locking (double-locking) with both hydraulic braking and a flow regulator, supplied as the left-hand version. Its 175¡ shaft rotation lets leaves open well beyond square on residential and industrial entrances, and with the whole drive below ground there is no bulky arm to spoil the look of a gate of up to 4 m and 700 kg.

The oil-hydraulic motor-pump and double-stroke jack form one compact unit that sits in a foundation box cemented below the gate at the hinge, so the operator is completely concealed. Bidirectional hydraulic locking holds the gate in both the open and closed positions. Adjustable hydraulic braking slows the leaf in both directions over the last 40 cm of travel. A flow regulator adjusts gate speed in both directions, suited to leaves wider than 2.5 m. Thrust is set with maximum and minimum pressure valves, while by-pass valves provide anti-crush safety. Fadini recommends an electric lock on leaves over 2.0 m.

Install it in a 745L zinc-coated or 762L stainless steel foundation box and connect it to a Fadini control board mounted in a sheltered place. Choose the left-hand (SX) model to match your gate, viewed from inside, and enjoy a clean entrance that opens and closes dependably.
