Choose a Swing Gate Motor by Gate Length & Weight

A swing gate motor must be selected from the length and weight of each individual leaf together with hinge geometry, wind exposure, opening angle, daily cycles and the manufacturer's application chart.

Total driveway width is not enough. A two-leaf gate with a four-metre opening normally has two approximately two-metre leaves, and each operator must suit its own leaf and mounting geometry.

Measure Each Leaf Separately

Measure from the hinge axis to the outer edge and record the construction weight of each leaf. Double gates can have unequal leaves, so do not assume both motors face the same load.

Why Length Changes the Permitted Weight

A longer leaf creates greater leverage at the hinges and motor brackets. Manufacturer charts often allow less weight as leaf length increases. Check the combined length-and-weight limits rather than separate maximum numbers.

Gate Construction and Wind

Open-bar gates allow air through, while solid sheets, timber or decorative cladding can create high wind forces. Wide solid leaves in exposed locations require particular assessment and may need an electric lock or different operator type.

Hinge Geometry and Pillar Depth

Record the distance from the hinge axis to the proposed bracket surface. Linear actuators require defined mounting dimensions; deep pillars or offset hinges may favour articulated arms. Underground operators need suitable hinge alignment and drainage.

Opening Direction and Angle

Confirm inward or outward opening and the required angle. Bracket geometry determines achievable travel. Check for walls, parked vehicles, rising ground and public-space conflict.

Single vs Double Gate

A single long leaf may experience more leverage and wind than either leaf of a double gate. Double gates need coordinated control, leaf delay where required and often an electric lock when the leaves overlap.

Daily Cycles and Duty

Estimate normal and peak operation. A residential leaf used several times daily differs from a compound entrance operating repeatedly. Select duty from the exact operator specification.

Choosing Operator Type

• Linear: compact and effective when hinge and pillar dimensions permit correct mounting.
• Articulated arm: useful for wide pillars or offset hinges with enough arm movement space.
• Underground: discreet, but requires foundation boxes, drainage and service access.

Information for a Recommendation

• Width and weight of each leaf
• Hinge and pillar measurements
• Open-bar or solid construction
• Opening direction and angle
• Daily cycles
• Photos of gate, hinges, pillars and driveway
• Power, backup and access-control needs

Frequently Asked Questions

Can I choose using total gate width?

No. Measure each moving leaf and check it against the operator's length-and-weight chart.

Why does a longer leaf need more care?

Greater length increases leverage and often wind load, reducing the weight an operator can safely handle.

Which motor suits a wide pillar?

An articulated-arm operator is often considered, subject to exact hinge offset and available space.

Do solid gates need stronger motors?

They can experience significant wind load. Capacity, geometry, locks and site exposure all require assessment.
