The Groxx GRXTBAS100 is a highly engineered, track-mounted Building Maintenance Unit (BMU) designed for complex architectural facades. This system integrates a high-reach telescopic boom with a specialized approaching mechanism to allow maintenance personnel to access recessed areas and navigate structural setbacks on high-rise buildings.
Telescopic Boom Dynamics: The heavy-duty boom provides extensive horizontal and vertical reach, featuring a rotation speed of approximately 6.1 m/min across a full ±180° range for total facade coverage.
Precision Approaching System: Specifically designed with a 4.2 m cradle approach, the system allows the suspended platform to move inward toward the building face, bypassing structural obstacles and ensuring the cradle is perfectly positioned for work.
Advanced Cradle Kinematics: The 3-meter cradle is capable of independent rotation of ±90° at 6 m/min, providing operators with the agility needed to follow complex building contours.
Integrated Dual-Hoisting: Features a primary cradle rated for 250 kg and an auxiliary hoist capable of lifting 500 kg, facilitating both personnel access and material handling (such as glass replacement).
Multi-Core Wire Rope: The system utilizes a 13 mm x 6 pcs steel wire rope assembly integrated with a copper conductor to ensure reliable hoisting and constant communication between the cradle and the roof car.
High-Capacity Braking: All moving parts, including the telescopic extension and the rotation arm, are equipped with automatic fail-safe braking systems.
Structural Robustness: The 62-ton unit is supported by a heavy-duty 300×300 steel track, engineered to manage the significant moments and dynamic loads generated during boom extension.
The GRXTBAS100 is designed and tested to comply with international safety regulations for permanent access equipment:
EN 1808:2015: Meets European safety requirements for Suspended Access Equipment (SAE), covering design, calculations, and stability.
Machinery Directive 2006/42/EC: Adheres to essential health and safety requirements for motorized industrial machinery.
ISO 9001 Quality Management: Manufactured under strict quality control processes to ensure long-term operational reliability in extreme environments.
This system is the ideal solution for modern skyscrapers with irregular shapes, deep recesses, or significant overhangs. The combination of the telescopic boom and the 4.2-meter approaching system ensures that no part of the building facade remains inaccessible to maintenance teams.
