Industrial Safety Guard Gas Struts: Selection and Mounting Guide
Gas struts for machinery guards and access panels are selected from the real guard mass, hinge geometry, opening path, mounting brackets, service access, environment, and machine-level safety requirements. A selected strut does not replace a system safety assessment.
Guard design review checklist
| Review area | Questions to answer | Evidence to retain |
|---|---|---|
| Motion | What force, opening effort, angle, and used stroke are required? | Drawing, calculation assumptions, and sample results. |
| Structure | Can hinges, brackets, fasteners, and panel material take peak loading? | Bracket details and finished-assembly test. |
| Safety | How is the guard supported for maintenance, failure, or service? | Machine risk controls and service procedure. |
What to send for an OEM review
- Guard drawings or photos in open and closed positions, moving mass, hinge position, and opening angle.
- Mounting coordinates, clearance envelope, stroke target, force target, fittings, and operating environment.
- Cycle expectation, contamination, washdown, vibration, service method, annual quantity, and validation criteria.
Frequently asked questions
Can a gas strut be the only safety support for a machine guard?
That decision belongs to the machine-level safety design. The full system should define independent supports, interlocks, and service controls where required.
Why test a strut in the finished guard?
Friction, hinge position, panel stiffness, temperature, mounting tolerance, and bracket load can change the real motion from a calculation.
