ANCLAJE DE BRAZO MOVIL
Introduction to the SAS Anchorage A-Frame
Overview of Construction Process
- The video introduces the SAS Anchorage A-frame, highlighting its seven key elements and the construction process.
- The assembly begins with positioning both axles (front and rear), ensuring wheels are locked off before attaching the main body.
Attaching Main Body Components
- The rear section of the main body is connected to the weight box using two sword pins, which are secured in place.
- The front section, including a shock absorber, slides over and locks into position with additional sword pins that are attached via rivets and chains.
Adding Diagonal Braces
- Three diagonal braces come with sword pins for secure attachment; ideally, two people should assist in this step for ease of handling.
- Each brace is lifted into housing points where spring-loaded sword pins hold them tightly in place.
Final Assembly Steps
Completing the Structure
- Once all components are assembled, they can be adjusted into position; total weight is 390 kg with a working load limit of 250 kg.
- Designed primarily for single-person use but compliant for rescue operations involving two individuals.
Usage Guidelines
- Recommended usage includes a minimum upstand of 300 mm; avoid open leading edges to ensure safety during operation.
Preparing for Operation
Tire Setup and Weight Loading
- Four pneumatic tires allow safe use on delicate membrane roofs; tires should be inflated before loading weights into the weight box.
- A total of 12 weights (25 kg each, six on each side) must be loaded after tire inflation to maintain stability.
Rigging Ropes Safely
- Ropes are rigged to I-bolts fixed at the main body; regular inspections every six months are crucial for safety compliance.
- Ensure even weight distribution across eyebolts and perform final checks on wheel locks and pin placements before operation.
