AweLock

AweLock central fast-locking manhole covers (manways) make work easier and safer thanks to  a state-of-the-asrt locking system that enables quick and safe opening and closing of pressure vessels.

Central fast-locking manholes are mainly used in the food, chemical and pharmaceutical industries or elsewhere where operator safety is the biggest priority.

CENTRAL FAST-LOCKING MANHOLE COVERS

PRESSURE INTEGRITY ASSURANCE

  • AweLock is designed to maintain pressure integrity within vessels.
  • The robust stainless-steel construction ensures that the manhole cover remains sealed under designed pressure conditions.

Accidental Opening Prevention

  • The central locking mechanism and support safety elements act as a barrier against accidental or unauthorized openings.
  • During pressurized operations, the AweLock remains securely closed, minimizing the risk of sudden releases.
  • This feature prevents human error or negligence from compromising safety.

OPERATOR PROTECTION

  • Operators working near pressure vessels face inherent risks.
  • AweLock provide an additional layer of protection by eliminating the possibility of accidental exposure to pressurized substances.

Legal Compliance and Liability Reduction

  • Companies that prioritize safety demonstrate their commitment to employee well-being and regulatory compliance.
  • By using central AweLock, companies mitigate the risk of accidents and potential lawsuits.
  • Compliance with safety standards ensures a safer work environment and protects the company’s reputation.

Safety precautions against opening under pressure

    • Pressure warning device – electrically operated.
    • After releasing internal pressure an electrical magnet releases a locking rod, cover can be opened.
    • Safety interlock switch – magnetic or safety inductive proximity sensor, to detect closed position of cover.
    • Pressure warning device – ball valve.
    • Hand-operated ball valve, whose operational lever reaches into the central locking mechanism. Before the opening of the manhole can be executed it must be checked whether the vessel is pressurized.
    • Catching device (optional)
      • Prevents the lid from opening if there is any residual pressure.
    • Backpressure prevention (optional)
      • Prevents opening of the central locking mechanism if there is residual pressure more than 0,2 bar.
