Triangle / Triangle


Street cleaners have to laboriously get them out from the small gaps, poking at them, and often have to lift the heavy steel cover off and place it by the side. This is both inefficient and dangerous.
As a solution to this, the "triangle" drainage cover design is suggested, which basically keeps the same shape as the existing drainage cover but which can transform slightly for better maintenance and management, as well as minimizing risk factors.
