The 10604 Trackless Bi-Folding Speed Gate consists of a post onto which a bi-folding leaf is attached by hinges. Unlike most bi-folding gate systems this does not require a track either in the ground or overhead to fold the leaf in half but uses a folding system housed inside a casing on top of the post hung leaf.
The patented 270° drive mechanism together with an electromagnetic brake locks the gate in both open and closed positions. The sinusoidal action of the drive allows the gate to operate in both a smooth yet fast action closing in 6 seconds (or 8 seconds in particular windy locations where a more powerful drive is used). The gate leaf sections are fully welded assemblies. The leaf frames are normally constructed of 60 x 60 mm RHS steel sections in-filled with closely spaced 30 x 30 mm RHS vertical bars with a maximum gap of 100 mm between. To reduce climb-over possibilities cross bars are not included below 3 m high.
Typically a gate can consist of a single unit of one post supporting one bi-folding leaf spanning up to 3.5 m. On wider openings typically up to 7 m span a pair of opposite handed units (a bi-parting pair) needs to be used. In the centre of the roadway a receptor plate will be required to receive the leading edge rollers when the gate reaches the fully closed position. The operation of the torque drive motor is controlled by a Programmable Logic Controller (PLC) based unit located within the associated control cabinet. All gate systems come complete with a through photo beam system between posts.
- Single unit:
- Width (maximum): (between motor post and receptor post), Standard drive 3.5 m, Hydraulic drive 4.0 m.
- Height (typical): 2.4 m, but can be higher with slight reductions to the maximum width.
- Bi-parting pair:
- Width (maximum): (between motor posts), Standard drive 7.0 m, Hydraulic drive 8.0 m.
- Height (typical): 2.4 m but can be higher with slight reductions to the maximum width.
Grit blast to SA2.5, hot zinc metal spray to 50 microns, pre-heat and etch, polyester powder-coat to 50 microns minimum.
Controls are Programmable Logic Controller (PLC) based and therefore are very flexible and can be configured to suit customer’s requirements.
