Heavy gates—typically over 500 pounds—require careful operator selection. Undersized operators fail prematurely; oversized wastes money. Here's how to choose correctly.
Weighing Your Gate
Estimation Method
- Steel frame: 10-15 lbs per square foot
- Wrought iron: 12-20 lbs per square foot
- Solid wood: 8-15 lbs per square foot
- Aluminum: 3-6 lbs per square foot
Accurate Measurement
- Bathroom scale method (for smaller gates)
- Professional weighing
- Manufacturer specifications
Operator Weight Ratings
Residential
- Light duty: Up to 400 lbs
- Standard: 400-700 lbs
- Heavy-duty: 700-1,200 lbs
Commercial
- Standard: Up to 1,500 lbs
- Heavy-duty: 1,500-3,000 lbs
- Industrial: 3,000+ lbs
Beyond Just Weight
Gate Length
- Longer gates need more torque
- Check length AND weight ratings
Duty Cycle
- Heavy gates at high frequency need larger operators
- Upsize for frequent use
Operator Types for Heavy Gates
Swing Gates
- Hydraulic operators for heaviest
- Ram-style for large gates
- Underground for clean appearance
Slide Gates
- Match motor to gate weight
- Consider cantilever for heavy gates
- Proper track/rollers critical
Common Mistakes
- Matching operator to minimum weight
- Ignoring gate length
- Not accounting for wind load
- Forgetting future changes (automation additions)
