Bi-Folding Trackless Speed Gate


The Eagle trackless bi-folding speed gate comprises a unique drive mechanism to control the opening and closing of a bi folding set of gates. This mechanism converts and controls both leaves producing a smooth but fast action. This unique design allows the gate to operate without the use of a bottom or top track, thus eliminating any height restrictions and large tracks in the road.


On entrance activation, the gates open in a quick but safe folding action. On approaching the gates from the inside, a vehicle will drive over an internal safety/exit loop. Traffic lights, if installed, indicate the gates are about to move and go green when safe to enter or exit. The gates stay open and then close after all the safety devices are clear and/or after a set time. An anti-tail gate function can be enabled to control traffic flow.


  • Galvanized and powder coated finish.
  • Heavy duty hydraulic ram with PLC controlled slowdown in both opening and closing movement.
  • Hydraulic design, low maintenance with minimal moving parts.
  • Smooth and quiet operation.
  • Trackless design, no height restrictions and lower maintenance.
  • Very secure with opening and closing in approximately 7 seconds.
