The Mutarail Seating System allows for the storage of rows on one side of the hall, underneath the stage, or within a platform under the floor. It suits spaces requiring different configurations, like auditoriums, theatres, and performing arts centres. The system design allows the sequential and individual movement of the rows, thus granting great versatility to the room to be able to configure the seating capacity desired at any time; with full capacity of seats, partial capacity or without seats. There are two parts of the system, the fixed and the mobile. The fixed parts are the extruded aluminum guides flush with the ground level. The mobile part is made up of cast aluminum carriages that slide along the guides, which support rigidly groups of up to 12 seats, mounted on an extruded aluminum profile, without bending, turning or twisting. The aluminum profile beam where the seats are fixed, gives maximum rigidity to the system, a quality that, together with the stability provided by the two carriages where they are mounted, offers a similar comfort to the one provided by any fix-foot seat. Thanks to its lightweight design, the Mutarail can operate automatically. The operation time depends on the layout of the hall. For safety reasons, the system integrates aluminum spacers in the rails to ensure a constant distance between rows and also brakes in the first row.
