basic information
The unique Ω shape, which gradually transitions from line contact to surface contact, exhibits soundproofing capabilities. The absence of protrusions on the sides allows for sufficient compaction, improving workability. It prevents uneven surfaces and water pooling, contributing to barrier-free access. The lightweight cover makes opening and closing easy, facilitating maintenance. Additionally, the installation workload is reduced, enhancing cost-effectiveness. It supports T-25 (5tf) loads. The two-tiered drainage structure significantly enhances water collection efficiency. There is a wide variety of covers available. In addition to concrete covers of L size 500 and grating of L size 995, combinations such as concrete covers of L size 475 plus safety grating are also possible. The handle has been removed from the top cover. By removing the safety grating first, the cover can be easily taken off without a handle. The lightweight cover is easy to open and close, and further safety measures have been implemented by creating a recess on the underside of the cover to prevent fingers from getting pinched during operation.
