PAMREX manhole covers are the most technically advanced covers on the market today. Made from ductile iron — an engineered material that offers many advantages over traditional cast iron — PAMREX covers deliver unsurpassed performance in all the key areas of concern to municipal engineers.
Ergonomics
PAMREX manhole covers are designed to be ergonomically positive — that is, easy for one person to operate, with no special equipment necessary.
• Hinged design
- Reduces physical effort required to operate by over 50%
- Retains cover in safe and controlled way during opening and closing
- Can be easily operated by one individual
PAMREX manhole covers are designed to be highly durable, a benefit that is made possible by the excellent mechanical performance of ductile iron.
• Four times the load strength of typical cast iron covers
- Capable of withstanding an average load of 120,000 lbs.
- Far exceeds AASHTO H20 heavy-duty loading standard: (32,000 lbs.)
- Independently tested and certified
• Gasket keeps cover silent and stable, even in heavy traffic conditions
- Absorbs traffic shock
- Tested for long-term durability
PAMREX manhole covers are designed to reduce the level of infiltration.
• Hinge design includes innovative “dual wiper” hinge housing plug
enabling hinge to remain self cleansing
• Elastomer gasket also helps reduce wet weather inflow
PAMREX manhole covers are designed to provide a range of security options to prevent unauthorized access.
• Two locking kits are available, can be retrofitted to cover
- PENTA locking kit — special locking wrench required to open lock
- SCS locking kit — spring-released locking key required to open lock
Safety
PAMREX manhole covers are designed for safe use by installers and maintenance personnel.
• Ductile iron
PAMREX manhole covers are designed for safe use by installers and maintenance personnel.
• Ductile iron
- Product weighs 50% less than typical cast iron covers, reducing risks of manual material handling (MMH)
- Safe mode of failure — even in unlikely event that cover dishes and/or cracks, it remains strong and stays in place
- Cover opens to 130º
- Hinge blocking feature prevents cover from accidental closure
