SAFETY MANHOLE SAFETY MANHOLE
- Development background: There are many manholes (openings) in water treatment plants and wastewater treatment plants for maintenance, machine inspection, and equipment input, and workers and pedestrians are always exposed to the risk of falling..
- At the same time as opening the manhole cover The handrail (safety railing) and blocking belt automatically unfold to block the opening.doing The world's first handrail-embedded safety manholeno see. It is a field-oriented technology that completely prevents safety accidents for workers and pedestrians.
Key Features
1 Key Features and Benefits
- Complete Dual Safety System Even when opening only one side of the cover (one door) for simple inspection or water collection work, the built-in handrail prevents falls. When the front is opened to insert equipment, etc., the handrails are automatically linked to form a handrail, completely preventing secondary falls of workers.
- Dramatic reduction in work time (Time Saving) Previously, when working on a manhole, it was necessary to install a separate fall prevention fence or safety zone marking strip, but safety manholes are constructed with safety equipment as soon as they are opened. Preparation and withdrawal times are significantly shortened as work can be done immediately using only a ladder and essential tools without any additional tools or preparation time.
- Safe pedestrian protection even in the dark In order to work safely even in low-light or dark underground treatment plants, we prevent pedestrians from falling by selectively applying luminous and LED ‘working’, ‘OPEN’, and ‘no access’ signs.
- One-person opening and closing and non-powered automatic system (Easy & Auto System) Even though it is a large manhole, it is designed so that one person can safely open and close it. The handrail opens and closes automatically using the rotational force (interlocked with precision gears) generated when opening and closing the cover, so no separate power or power is required.
Operating sequence
2 product type
1 DOOR opening / inspection door type (for inspection and water collection work)
Optional open and solo operation: Even if it is a large manhole, there is no need to open the entire manhole for the sole purpose of inspection or collection of treated water. Open only one door (manhole on one side)You can use it by. The covers are individually divided and designed to be fully site-oriented so that one person can sufficiently open and close them.
Complete fall protection: Even if only one door is opened, a secondary fall prevention barrier is immediately formed at the bottom by the built-in handrail and blocking belt, completely protecting the safety of workers and pedestrians.
Form of **’single-stage manual manhole with built-in handrail’** that opens in a single structure
2 DOOR (front open) / equipment entrance type (for equipment insertion and facility maintenance)
Front opening and automatic handrail forming: If it is necessary to perform facility maintenance or bring in bulky mechanical equipment, use ‘Full Opening (Facility Maintenance Mode)’ by opening both doors.
- Safety handrail interlocking system: When the two doors are fully opened, the manhole cover and the handrail interlocked with precision gears unfold together to form an ‘automatic protection railing’** surrounding the entire large opening..
- This system prevents secondary falls of workers even if the wide equipment entrance is open and prevents major accidents by making sure passers-by are aware of the work area.
