Special Self-Supporting Gates for Large Openings

Challenge

Self-supporting gates are perimeter closing systems that require no track or rail at the bottom. They provide a greater advantage over gates with sliding rail systems because they can operate all year round, regardless of the weather (snow, ice, gravel on the road, etc.).

The product is not usually complicated but poses a real challenge when needed for large openings. Moreover, when the customer requests that the gate be clad with metal sheet, it must be constructed in such a way that it can withstand the force of the wind because it acts like a movable wall. In such a case, for a self-supporting gate to function within its required parameters, it is necessary to create and install a special system.

Approach & Results

EMI has created the largest self-supporting gate to date, for an 18-metre opening, clad in metal sheet, made in a single-leaf. The length of the product also required special transportation, handling, and installation conditions.

Other Special Projects

Chernobyl

In 2019 we carried out an exceptional project from all points of view, in which we equipped and fitted all the technical buildings in the Chernobyl Reactor 4 area with fireproof metal swing gates, including the sarcophagus installed a few years ago on top of the old one, erected immediately after the 1986 explosion.

Clinceni

Finding optimal solutions in the design, construction, installation, and maintenance of aircraft hangar doors requires a high level of innovation, flexibility, and adaptability in the field, given the particular conditions of the airfield - atypical dimensions for opening and gauge, high frequency of use of the access system, the need for special handling protection systems, the imperative of prompt response to damage.

Special Gates for Overhead Cranes

They are designed by EMI for manufacturers of precast concrete, metal, or other large-scale ironworks that use overhead cranes to handle products from the production hall to the outside. The installation of this type of gate leads to a substantial reduction in exposure to temperature differences in the gap created by the movement of the overhead crane, regardless of the season.

Remodelling of Underground Transport Depot

The project to remodel an underground transport depot involved refurbishing the entire façade and fitting special gates in existing voids that had to meet the new requirements, taking into account two particular conditions: at the bottom, there was a railway line, over which the gates had to pass, and at the top, there was a high voltage line (27,000 V).
