Scope of Works
Consultancy and Planning
GrainCorp had a unique goal to achieve in the selection of their door application; to contain combustible dust. The fine nature of the canola oil grain dust makes it prone to combustion if ignited in large amounts, so dust containment in the facility is essential. Therefore, a Movidor high speed folding door was installed on an exterior opening, to contain dust and noise inside the facility.
Being a 7000mmW x 5100mmH opening, a high speed door was required that could provide prompt, efficient access to the facility whilst still maintaining wind rigidity. Featuring a customised self-supporting Galvanized frame with a double-beam head section, this folding door was designed for sheer size, with a single skin curtain supported by steel beams, and hoisted by vertical belts running onto an overhead drum. A stainless steel motor cover ensures the motor and controller is protected from the elements, and will not corrode with rain or moisture exposure.
Simple in design and operation, longevity and low-maintenance are some of the hallmarks of this high speed folding door.
Due to the combustible nature of the dust, safety was a huge consideration for this company. This led to GrainCorp's selection of a ream of safety accessories in the door specification, to maxmimise the protection of traffic through the opening. With integrated PE Beams in the door frame, the folding door is able to detect pedestrian traffic when the door is closing, and provided an added level of safety to traffic going through the opening. GrainCorp also opted for induction floor loop detectors for activation on the inside of the opening, as a safety sensor to prevent the door from closing.
This folding door was also fitted with a four-piece integrated traffic light system. The LED lightstrips run Blue while the door is closed, but turn Red when the door is opening and closing and when the door is at its open state, the lights turn green. These lights are recessed into the door guides, and are visible from both sides of the opening.

In December 2019, an extension upgrade was made to the Ridley Agriproducts facility, installing a Movidor high speed door for dust control and efficiency on their grain pit.
If not properly contained within the grain pit, the dust travels from trucks when releasing a load of grain into the pit, and can quickly become problematic! View this project to learn how high speed doors can be used for dust control within the milling and grain industry.
