Types of Machine Guards: Choosing the Right Solution for Your Equipment
When it comes to protecting workers and equipment, selecting the right type of machine guard is essential. The right guard helps you stay compliant with OSHA requirements, reduces downtime, improves workflow, and keeps your team safe.
At WireCrafters, we manufacture machine guarding systems designed to fit your specific application. From standard options to fully customized enclosures, our guards provide durable, adequate protection that integrates with your facility’s layout.
Here’s a look at the most common types of machine guards and how to determine which is best for your equipment.
1. Fixed Guards
Fixed guards are permanent barriers that prevent access to hazardous machine parts. They don’t move during operation and typically surround parts of the equipment that don’t require operator interaction.
Best for: Equipment that does not require frequent access, such as motors, belts, or gear assemblies.
Our solution: Our modular guarding panels create fixed barriers that can be mounted directly to the floor or machine frame. Panels are constructed of welded wire mesh for visibility and airflow while maintaining strong physical protection.
2. Interlocked Guards
Interlocked guards are designed to shut down the machine when the guard is opened or removed. These are ideal for machines requiring frequent loading, unloading, or maintenance access.
It is best for Automated systems, robotic cells, and CNC machines where access points must be controlled for safety.
Our solution: Our machine guarding systems are compatible with most safety switches and interlocks. Depending on your workflow needs, doors can be configured with hinges, slide tracks, or lift-up access.
3. Adjustable Guards
Adjustable guards offer more flexibility and are typically used when the machine operates on various material sizes. These guards can be moved or repositioned to accommodate the work being done, though they require careful attention to ensure they’re always correctly in place.
Best for: Milling machines, drills, and grinders with varying dimensions or use cases.
Our solution: We offer custom-built guarding solutions with adjustable components designed to accommodate variable operations while maintaining OSHA compliance.
4. Self-Adjusting Guards
These guards move automatically as the operator uses the machine, exposing only the portion necessary for the operation while shielding the rest. They are commonly used in woodworking or material-cutting machines.
Best for: Saws, routers, or machines where the point of operation changes during use.
While WireCrafters does not manufacture self-adjusting components, we can provide guarding systems that enclose these machines safely, often in combination with fixed or interlocked guards to create a safe perimeter.
5. Perimeter Guards
Perimeter guards isolate entire machines, robotic cells, or production areas to prevent workers from entering hazardous zones during operation. These are often paired with access control features.
It is best for Robotic work cells, automated material handling systems, and high-speed machinery.
Our solution: Our modular perimeter guarding systems are built using wire mesh panels and posts that can be installed quickly and reconfigured. Optional hinged or sliding doors allow for controlled access, and panels can be powder-coated in safety yellow for high visibility.
Choosing the Right Guard
Every machine and operation is different. The best guard for your application depends on several factors:
- Frequency of operator interaction
- Type of hazards (moving parts, flying debris, pinch points)
- Layout and space constraints
- Need for visibility and airflow
- Required level of access control
At WireCrafters, we work with integrators, safety managers, and engineers to design guarding systems that meet safety and operational needs. Whether outfitting a new line or updating an existing one, we can help you find the right solution.
