Bi-parting cantilever gates for 20 m+ openings
Two synchronized leaves meet in the middle, halving travel distance and opening time on very wide entrances.
36 m
maximum clear opening with two leaves
2x
faster opening than one leaf of the same span
~40 cm
center offset for opposite opening
16.5 m
each leaf on the Maldives airport gate
Double or opposite opening
In double opening, both leaves run on the same line and their centers must align so they meet cleanly. In opposite opening, the leaf centers are offset by about 40 cm so the two leaves pass each other without collision.
A shared controller keeps both drives synchronized, and each side has its own infrared sensors and safety edge.
When to split one leaf into two
One leaf can clear up to 18 m, but its total length is about 1.5 times the opening, so it needs a lot of side space and takes longer to open. Two leaves need less run-back on each side and open in half the time.
Airports, ports, bus depots and stadium service roads are typical cases.
