Groxx Mini Davit Arm
The Davit Arm Glass Replacement Unit (GRU) is a high-efficiency architectural maintenance and rigging assembly engineered specifically for handling glazing units and heavy cladding elements during building installation or replacement operations. Combining a lightweight, high-tensile structural aluminum boom layout with a high-torque electric winch setup, this system provides precise, smooth control over material handling at high altitudes.
This consolidated data sheet details the complete mechanical and electrical parameters for the GGDGRU250 system, integrating the structural crane configuration and its companion heavy-duty electric hoisting unit.
Advanced Structural Metallurgy: Built using high-strength Aluminum 6061/T6 for the primary upper boom, post, and monorail assemblies to significantly reduce self-weight, easing handling on rooftop setups while guaranteeing maximum structural stiffness.
Robust Foundation Interfaces: The turning components, fixed mount points, and oversized foundation base are forged from heavy-duty Hot-Dip Galvanized (HDG) Q345-B carbon steel to ensure rigidity against large structural overturning moments and extreme outdoor weathering.
Integrated Turning Kinematics: Equipped with a built-in heavy-duty rotating manual slewing interface (“Turning Kit”) allowing for smooth pivot arcs during tight glass tracking maneuvers over roof edge boundaries.

High Strength-to-Weight Optimization: The $\varnothing 200 \times 8\text{ mm}$ structural aluminum post design minimizes architectural load impact on roofing systems, simplifying manual shifting and alignment between multiple pre-installed base sockets across floor layouts.
Industrial-Grade Hoisting Power: Driven by a premium 3500W, three-phase high-torque electric winch engine. This motor features Class F thermal insulation properties, providing high-cycle lifting speed stability (10m/min) over deep vertical drops up to 30 meters.
Corrosion Protection Matrix: Combining premium anodized structural alloys with hot-dip galvanized steel sub-assemblies creates an effective barrier against water intrusion, rust tracking, and atmospheric oxidation, maximizing product lifecycle longevity during outdoor construction phases.
