After that, won the Minister of Land, Infrastructure and Transport Prize in 2007. In 2010, all models of Monban received authorization of an eco-mark. The new model, happy gate monban system won the Japanese Grandprix Prize for an excellent work in 2012.
Happy gate monban system succeeded in miniaturization by building the control unit in the frame (or the shutter box) instead of installing it beside the sheet shutter. It is expected to become a defact standard of the industry. Happy gate monban system was exhibited as "New type of the sheet shutter which can create the space value" on the Machine Element Technical Exhibition held in Osaka in October of 2012 and it became the center of attention. It can be used widely as integrated system with the air shower, air cuitain and partition and so on.
Speed of the pipeless type G is 3m/sec..It has the self-repairing system that the sheet can re-set automatically by one time full-open operation after going out of the side frames in case of collision. The sheet reverses to open at low speed (0.5m/sec.) in case of collision and it reverses to open at middle speed (1.5m/sec.) in case of detection of the sensor. Lightweight structure makes possible escape in case of emergency only by releasing and lifting up bottom of the sheet. Operation is possible in case of power failure with the optional battery for emergency.
Happy gate monban for the cold storage and freezer can be used for the partition of the cold storage of -25℃ to +5℃. Happy gate monban controlled by the air was developed for the exposionproof area. And monban unit for integration with facilities which can be integrated with the air shower, air curtain, conveyer and elevator creates various kind of the space value.
