At Ohmoto Corporation, we provide a technology called "Current Resistance Type Water Quality Pollution Prevention Frame" that suppresses the deformation of curtains caused by tidal currents or the lifting and lowering of grab buckets when using water quality pollution prevention frames. In conventional technology, the work suspension criteria related to tidal currents is around 3 knots, but with this technology, work can be performed against tidal currents of approximately 4 knots. 【Features】 ■ Prevents the spread of pollution due to curtain damage caused by the reduction of effective curtain length or contact with the edges of the grab bucket. ■ Prevents curtain damage caused by contact with the edges of the grab bucket, eliminating the need for curtain replacement, thus improving cost-effectiveness and workability. ■ Allows work to continue without waiting for tidal currents to subside, enabling a reduction in project duration. *For more details, please feel free to contact us.
