SAFETY MANHOLE Safety Manhole
Safety Manhole (Automatic Guardrail Interlocking)
Official Performance Certification by the Ministry of SMEs and Startups • Non-powered automatic handrail that deploys immediately upon opening
Official Performance Certification by the Ministry of SMEs and Startups • Non-powered automatic handrail that deploys immediately upon opening
This is the world's first innovative public safety infrastructure solution developed to prevent fall accidents at manhole openings scattered across water/wastewater treatment plants and pedestrian walkways. By mechanically interlocking the physical rotational force generated when the cover is opened using precision gears, fall-prevention guardrails and safety barrier bands that fully pass ANSI/OSHA standards are automatically deployed around the opening.
World's First Safety Manhole 4-Axis Opening and Closing Drive Simulation
This is an interlocking model video where the fall-prevention guardrail is automatically projected through precision gear interlocking without any mechanical delay the moment the manhole cover is opened. Clicking on each type card below will immediately play the corresponding simulation video.
1 DOOR Open Type (For inspection/sampling)
This is for routine water quality measurement sampling and simple visual inspection of collectors in sewage sedimentation tanks, etc. Even if only one door is opened, the built-in handrail and safety barrier band firmly block the lower section, reliably protecting the worker's safety during inspection.
2 DOOR Fully open type (facility maintenance/equipment import)
It is applied when large-area input is required, such as seating a large-scale mechanical gear unit or repairing a lower pump. An extra-large guardrail bar is formed surrounding the four sides in conjunction with the rotation angle of opening the two doors, transforming the fall hazard zone into a safety zone.
4 DOOR inspection hole type (4-way guard fastening)
This lineup is suitable for large underground cavities or public pits with enormous diameters. Depending on the purpose of individual inspection, four doors can be opened sequentially or simultaneously, and the gear linkage is designed in a multi-axis manner to prevent fence distortion or malfunction.
4 DOOR equipment entry type (non-powered lifting)
This is a dedicated elevator infrastructure lineup that opens and closes all four doors in a large area without power to transport large rotating machines, pumps, and heavy inspection equipment into and out of underground facilities.
Product Key Features
- Non-powered automatic linkage: purely mechanical precision gear linkage operation without external power supply or switch
- One-person opening and closing design: A large, heavy manhole cover is easily operated by one person by combining a precision hinge and an auxiliary compensation mechanism.
- Dual Safety Structure: Individual guards automatically operate even when partially opened from 1 DOOR to 4 DOORs to suit the required area.
- Shortened safety process: Maximizes work efficiency by omitting the installation procedures for separate temporary fences or mobile alarms.
- High-visibility light-emitting structure: Selectable luminous and high-brightness LEDs can be installed, making them visible at night or in underground treatment plants with insufficient illumination.
- Super engineering plastic guard ensures wear resistance and semi-permanent lifespan
Existing conventional manhole vs. Rincon handrail automatically linked safety manhole
| Compare items | Existing conventional manhole | Rincon safety manhole (complete with performance certification) |
|---|---|---|
| Required opening and closing manpower | At least 2 people involved (high physical load such as back injuries) | Can be opened independently by one person (auxiliary gas spring and hinge mechanism) |
| fall arrest device | After opening, a separate movable safety guard is required and manual installation is required. | Automatic safety guardrail formation without power as soon as the cover is opened |
| work time required | Requires significant preparation time to transport, install and remove portable fences | Safety zone is completed as soon as manhole is opened, reducing preparation time by 90% |
| External power/tools | Requires assembly tools or heavy support fixtures for installation | Purely mechanical and non-powered (no additional power or assembly tools required) |
| Flexible maintenance | Since the cover is integrated, it must be completely opened, so there is no risk of falling. | Individual doors can be split and opened according to the purpose (simple inspection, equipment insertion) |
