System intent

Designed around the task—not simply the available component.

Guard locking retains a movable guard closed until the hazardous condition has ended or the safety system authorises release.

We develop the guarding arrangement in the context of machine movement, product flow, operator behaviour, cleaning and foreseeable intervention. The scope is then defined clearly for detailed engineering and installation.

Key engineering decisions

What the design needs to resolve.

These points are reviewed together because a change to access, stopping or production flow can alter the required safeguarding approach.

  1. 01

    Reason for locking

    Establish whether locking protects people or is used primarily for process control.

  2. 02

    Release condition

    Use monitored standstill, safe speed, timer or process feedback appropriate to the residual hazard.

  3. 03

    Escape and emergency release

    Provide a way to leave or release the space where a person could become trapped.

  4. 04

    Power-loss behaviour

    Select power-to-lock or power-to-unlock behaviour in the context of risk and emergency access.

Industrial machine access control and emergency stop station

Application review

Design considerations.

  • Machine run-down and stored energy
  • Access demand and production sequence
  • Solenoid monitoring and fault response
  • Escape release and whole-body access
  • Manual release for maintenance
  • Door strength, alignment and handle system
Arrange a site survey

Typical project output

What can be included in the scope.

The precise deliverables are agreed before work proceeds and depend on whether the project covers mechanical guarding only or an integrated safety-system modification.

  • Guard-locking selection
  • Mechanical mounting and handle system
  • Release logic and indication
  • Escape or emergency release where required
  • Functional and fault testing
  • Handover and maintenance instructions

Start with the hazard, access task and stopping behaviour

Discuss your machine guarding project.

Send photographs, a layout or a short description. We will help define the survey, design and integration scope.
