PRISMONT Articulated Arm Extension – Detailed Description
The MST-BA01/325 articulated arm extension is an accessory designed to extend the reach of compatible PRISMONT safety guards. It integrates directly with existing systems using friction-articulated arms, ensuring smooth, stable, and precise positioning of the protective screen.
This extension is particularly useful when the workstation requires expanded coverage, improved clearance around the part, or adaptation to a specific machine configuration.
Each kit includes one articulated arm and all the necessary accessories and bolts. It is available as a single articulated extension with a 325 mm reach.
Why Add an Articulated Arm Extension?
Adding an extension arm allows you to:
- Increase the positioning flexibility of the safety guard
- Cover a larger working area
- Improve workstation ergonomics
- Adapt an existing guard without full replacement
It is a simple and cost-effective way to upgrade an existing installation.
Advantages of the Additional Articulated Arm
The additional articulated arm increases the reach of a compatible PRISMONT safety guard without replacing the existing installation. It provides a flexible solution to adapt the protective coverage to real workshop needs.
- Increases guard positioning flexibility
- Expands protective coverage area
- Improves accessibility and ergonomics around the machine
- Avoids full guard replacement
- Cost-effective upgrade solution
- Maintains the original interlocked guard’s safety level
Integration and Compliance
The additional articulated arm does not include an interlocking device. It is designed exclusively for use with compatible PRISMONT safety guards equipped with a friction-articulated arm system.
When installed on a compliant interlocked PRISMONT safety guard, the complete system maintains its safety level and conformity with OSHA, ANSI, ISO-EN, and CE standards. The extension does not alter the operation of the micro-switch or the guard’s existing interlocking logic.
