The mechanism is the part of a barrier gate that converts motor rotation into the controlled movement of the boom, and it is the component that determines how many cycles a lane can handle before maintenance is required. This page describes the mechanism architecture that SUNFRE builds for its high-speed parking and toll barrier gates, the specification range that can be supplied, the boundaries within which the design can be adjusted, and the commercial terms that apply when mechanisms are ordered as components or as part of complete units. Buyers comparing complete installations should also consult the barrier gates guide.
SUNFRE fits planetary reduction gearboxes to all of its high-speed barrier gates; the single-stage gearbox uses rolling contact, is specified at 97–98% efficiency, and has low backlash, a combination that limits the lost motion that would otherwise accumulate over repeated reversing cycles. Three motor lines are manufactured for these mechanisms, covering AC, BLDC and DC servo drives, with the DC servo line positioned as the upgraded option for sites that need faster and more closely controlled movement. Servo mechanisms are configurable to opening times of 0.3 s, 0.6 s and 0.9 s, and the opening time can be adjusted up to 6 s where a longer boom or a slower traffic pattern requires it.
The parameters below describe the range that is available across the standard mechanism platform. Values that depend on the selected boom length, cabinet configuration or site duty cycle are confirmed against the specific model at the time of enquiry rather than assumed from this table.
| Reduction gearbox | Planetary, single-stage, rolling contact, 97–98% efficiency, low backlash, fitted to all high-speed barrier gates |
|---|---|
| Motor lines | AC, BLDC and DC servo; DC servo is the upgraded line |
| Servo opening times | 0.3 s, 0.6 s and 0.9 s, adjustable up to 6 s |
| MTBF | 5,000,000 cycles |
| Complete-machine design life | Exceeding 10,000,000 cycles (a distinct metric from MTBF; the two are not interchangeable) |
| Ingress protection | IP54 |
| Operating temperature | −20 °C to +75 °C |
Control of the mechanism, including fail-safe behaviour on mains failure and the detection logic that protects vehicles, is described separately in the company’s comparison of barrier gate anti-crush protection methods.
Adjustments that sit inside the published mechanism platform include the selection of motor line and the opening-time configuration described above, together with the boom and cabinet combinations that are matched to those settings. Requests that concern controller-level firmware branding, label language, supported reader protocols, spare-part numbering or dedicated tooling are to be confirmed with SUNFRE for the specific project, since the company does not publish a fixed list of such options. Buyers planning an OEM or ODM programme can review the way these boundaries are handled in the OEM and ODM capability overview.
SUNFRE’s published commercial guidance states that standard models often carry a low minimum order quantity, that customised finishes or branded firmware require larger batches, and that buyers should confirm the MOQ per model and whether mixed-SKU containers are accepted. Sample availability and terms are confirmed on a per-model basis. The full wording is set out on the company’s minimum order quantity and lead time page, which should be treated as the reference for commercial terms.
According to the same published guidance, standard items may ship in 1 to 2 weeks, while customised OEM runs take longer, and the schedule must include additional buffer for sea or air freight together with customs clearance and last-mile delivery. A written lead time for a customised mechanism is issued with the quotation once the configuration and quantity have been settled, rather than quoted as a fixed interval on this page.
Product documentation is available in the form of the SUNFRE products catalogue and the model-specific brochures covering the SFBG102 barrier gate and the S10 DC servo barrier gate. Certificates and test reports are available on request through the enquiry channel, where the documentation relevant to the destination market can be identified for the specific model. Buyers should state any certification or test-report requirement at the outset so that it can be attached to the quotation.
Readers comparing pedestrian equipment can review the turnstile mechanism and control page, and those evaluating a supply partnership can consult the OEM and ODM capability overview and the company and manufacturing overview. SUNFRE does not display public pricing; project requirements, quantities and destination markets should be submitted through the contact page for a quotation.
