Rack and Pinion Versus Chain-Driven Slide Gate Openers

All PPA slide gate openers utilize the rack and pinion operation method. Rack and pinion has been more popular in Europe but is gaining popularity in North America because its operation has many benefits compared to chain-driven slide gate opener operation. How each works, their common applications, and the pros and cons are all discussed below. Note, all PPA slide gate openers utilize the rack and pinion operation method and are linked below for your convenience.

How Rack and Pinion Slide Gate Openers Work

Rack and pinion slide gate openers have a rack with teeth spanning the length of the gate and a pinion, or gear, mechanized on the opener. The rack is bolted to the side of the bottom of the gate frame with the teeth pointing downward. The pinion, or gear, interacts with the teeth on the rack to move the gate back and forth or open and close.

Common Application

Rack and pinion slide gate openers, which are popular in Europe, are commonly used in warmer climates and can withstand heavier loads and more frequent use.

Rack and Pinion Pros

  • Handles heavy loads
  • Withstands frequent use
  • Smooth operation: precise & controlled movement
  • Noise reduction
  • Little maintenance required
  • Noise reduction
  • Irreversible: cannot be pushed & stops upon obstruction

Rack and Pinion Cons

  • Installation: requires more consideration & modification
  • Suited for warm climates

How Chain-Driven Slide Gate Openers Work

Chain-driven slide gate openers utilize a chain attached to both ends of the gate by a bracket. The chain runs the length of the gate through two idlers and a power-driven gear.

Common Application

Chain-driven slide gate openers, which are more popular in North America, are better suited for cooler climates because the suspension of chains can better handle large debris like snow.

Chain-Driven Pros

  • Easy installation
  • Suited for any climate
  • Better suspension

Chain-Driven Cons

  • Noise
  • May leave grease line in driveway
  • More frequent maintenance
  • Less precise and controlled movement
