Groxx Mini Davit Arm
The Groxx GRXL71 is a high-performance, wall-mounted (face-mounted) monorail track system engineered to support permanent building maintenance units (BMUs) and suspended cradles. Mounted directly to the building’s concrete walls, structural beams, or slab edges via heavy-duty steel brackets, this robust track profile serves as a continuous horizontal pathway for motorized or manual trolleys. It provides an ideal solution for accessing vertical glass and cladding faces where roof-mounted crane systems are structurally restricted or architecturally restricted.
Vertical Facade Navigation: Optimized for long, straight runs and vertical structural envelopes where an exterior face-mounted system is preferred over ceiling placement.
Contour Adaptability: The continuous extrusion is designed for structural precision and can be custom-bent to follow the architectural profile and facets of the building envelope.
Low-Profile Integration: Typically positioned parallel to the floor slab edge or behind specialized architectural louvers, making the permanent maintenance track completely invisible or highly integrated into the facade aesthetic.
High-Yield Metallurgy: Extruded from structural 6061/T6 Aluminum Alloy, striking the perfect balance between exceptional structural yield strength and vital lightweight handling.
Diamond-Shape Structural Geometry: Utilizes an advanced diamond-shaped profile geometry to optimize torsional rigidity, minimize lateral swing, and maintain flawless tracking for traversing trolleys under full dynamic loads.
Robust Span Optimization: Configured to be securely supported by brackets at extended structural intervals ranging from 1.0m to 2.5m, allowing flexibility based on substrate integrity and design load targets.

The GRXL71 system is fully engineered, analyzed, and third-party certified to comply with EN 1808:2015 (Safety requirements for suspended access equipment – Design calculations, stability criteria, construction – Examinations and tests):
BMU Classification: Designed to safely support self-powered platforms (cradles), single-user chairs, or dedicated glass-lifting material winches, integrating all factor multipliers for permanent installations.
Deflection Constraints: Rigorously calculated to resist structural deflection between anchors, preventing track distortion under dynamic braking or sudden descent arrests.
Corrosion Resistance: The aluminum assembly features an anti-rust architectural finish, paired with hot-dip galvanized structural brackets to survive harsh environmental exposure over decades.
Cost-Effective Efficiency: Recognized as one of the most cost-effective and operationally efficient window-cleaning infrastructures available, featuring incredibly low running costs and minimal physical operational steps.
Anchoring Integration: For secure face-mounting to reinforced concrete shear walls, the system brackets integrate perfectly with Groxx GRX851 Epoxy Adhesive systems, ensuring an exceptionally high pull-out and shear capability to support the cantilevered track moments.
Seamless Travel Path: Features smooth, burr-free splicing joints that prevent trolley jamming or chatter, providing maintenance technicians with a smooth, continuous travel experience along the entire perimeter of the building.
