Non-Penetrative Weighted Anchor Solutions

Non-Penetrative Weighted Anchor Solutions

WeightAngel provides mobile fall protection through sophisticated counterweight methodology, engineered specifically for situations where permanent anchor installations prove unworkable. This portable weighted anchor system addresses the critical need for temporary fall protection on flat roof applications up to 5° pitch, delivering certified performance without structural modifications or membrane compromise.

The system addresses the practical challenges of short-term maintenance and construction activities through intelligent counterweight design that maximises anchor reliability whilst minimising installation complexity. With proven performance across multiple substrate types and certified compliance with BS EN 795:2012 Class E standards, WeightAngel establishes new benchmarks for temporary fall protection effectiveness.

Comprehensive testing validation across concrete, asphalt/ashfelt, and single-ply membrane surfaces provides contractors with documented performance assurance, whilst the system’s compact configuration and operational capacity delivers enhanced project efficiency without compromising safety standards.

Why Choose WeightAngel

• Multi-Substrate Certification
  SATRA-verified performance to BS EN 795:2012 Class E across concrete, asphalt/ashfelt, and single-ply membrane surfaces ensures consistent anchor reliability regardless of roof construction, backed by independent testing evidence and comprehensive substrate compatibility data.
• Rapid Deployment Engineering
  Streamlined assembly system with intuitive component configuration enables swift installation and removal, minimising time at height.

Technical Specifications & Features

WeightAngel incorporates precision-engineered counterweight mechanics with validated friction coefficient analysis to deliver certified temporary anchor performance. Our system achieves BS EN 795:2012 Class E compliance through SATRA-verified load testing protocols, whilst maintaining deployment efficiency across varying substrate conditions. Every component undergoes rigorous structural analysis for coefficient of friction optimisation, material density calculations, and substrate-specific load distribution modelling to ensure predictable anchor performance under dynamic loading scenarios.

• Calculated Friction Anchor Mechanics
  Engineered counterweight assembly (Ø1200mm) utilises optimised mass distribution through recycled materials, generating friction forces exceeding Class E requirements whilst eliminating roof penetrations and maintaining substrate integrity across membrane, concrete, and bituminous surfaces.
• Multi-Substrate Load Verification
  SATRA-certified performance across concrete (>25N/mm²), ashfelt/asphalt, and single-ply membranes through friction testing, deformation analysis, and edge loading assessments on roof pitches up to 5° maximum.
• Optimised Footprint Engineering
  Ø1200mm circular geometry minimises point loading (<2.5kN/m²) whilst maximising contact area, incorporating low-profile assembly to reduce trip hazards and accommodate restricted roof access with minimal disruption.
• Materials Engineering Analysis
  High recycled content composition (>60% post-consumer materials) engineered for optimal density-to-volume ratios, providing predictable mass characteristics whilst meeting sustainability targets and cost-effectiveness through lifecycle optimisation.
• Integrated Load Transfer System
  Purpose-engineered interface compatible with RoofAngel posts, featuring calculated moment resistance through validated connection protocols, enabling user operation with documented safety factors and verification procedures.
