The Groxx Mini Davit Arm (Model NO: GRXLPD90) is a high-strength, low-profile industrial crane system engineered for architectural maintenance, facade access, and localized material hoisting operations. Combining a lightweight, high-tensile structural aluminum upper assembly with a heavy-duty galvanized steel foundation matrix, this compact davit system provides stable load-bearing performance and smooth rotational control over edge boundaries.
High-Strength Aluminum Upper Assembly: The main column post, structural boom, and integrated monorail tracking are manufactured from premium Aluminum 6061/T6. This significantly minimizes the system’s dead weight for easier manual handling and installation while ensuring exceptional structural rigidity.
Heavy-Duty Galvanized Steel Foundation: The primary fixed mounting points, rotating assembly, and base structural hub are forged from premium Hot-Dip Galvanized (HDG) Q345 / Q345-B Carbon Steel. This combination provides high tensile strength to withstand extreme overturning moments while delivering multi-decade resistance to atmospheric rust, corrosion, and weathering.
Smooth Rotational Slewing Kinematics: Features an integrated manual slewing handle and turning kit component to facilitate smooth, controlled rotation when swinging equipment or materials over roof boundaries and parapets.
Optimized Load Distribution Footprint: The heavy-duty $400 \times 400\text{ mm}$ base plate utilizes a multi-bolt anchoring pattern engineered to safely transfer compression, tension, and shear loads into the concrete substrate or supporting structure.

The system features precise physical geometries optimized for tight industrial envelopes and structural parapet environments:
Outreach Radius: Offers a rigid 1500 mm horizontal clearance from the centerline of the vertical post to the terminal load connection points, ensuring ample clearance from building facades.
Structural Clearance: Standardized with an overall height of 1815 mm and an intermediate turning height clearance of 1599 mm, providing excellent vertical clearance for personnel or material baskets.
Base Mounting Pattern: Engineered with structural gusset reinforcements and an anchor layout featuring standard $\varnothing 40\text{ mm}$ clearances for heavy-duty fixing fasteners.
Strength-to-Weight Optimization: Utilizing an engineered $\varnothing 200 \times 8\text{ mm}$ aluminum column ensures the weight of the portable upper arm components remains low. This reduces worker fatigue during setup and teardown while comfortably delivering a 250 kg Safe Working Load.
Industrial Corrosion Defenses: By marrying an anodized structural aluminum upper assembly with hot-dip galvanized steel base hardware, the crane prevents galvanic corrosion and stands up to harsh coastal, marine, and urban rooftop environments.
Flawless Shuttling Integration: The dedicated $116 \times 70\text{ mm}$ aluminum monorail profile allows for the direct attachment of compatible manual material trolleys or traveling personal hoists, providing fluid movement along the load path.
