Cowest BVL Series: Professional Auto‑Balanced Glass Handling Solution for Overhanging Eaves Facade Projects
Cowest BVL auto‑balanced glass installation machine with 1000–2000kg load capacity, 360° rotation, long extension, designed for safe and efficient overhanging eaves exterior glass installation.
In modern architectural construction, the installation of exterior curtain wall glass—especially on buildings with overhanging eaves—demands higher precision, safety, and flexibility than ever before. Traditional lifting equipment often struggles with limited reach, unstable posture, and difficult positioning under eaves, leading to low efficiency and potential safety hazards. The Cowest BVL Series auto‑balanced glass installation machine is engineered to overcome these challenges, providing a reliable, all‑round solution for glass installation in high‑rise buildings, commercial structures, and complex facade projects with external eaves.

At the core of the BVL series is its advanced auto‑balancing system, which maintains stable load holding at any extension distance. This intelligent design eliminates shaking or tilting during glass handling, ensuring steady and secure operation even in the narrow, restricted space beneath overhanging eaves.
The machine offers full‑range electric motion control, including 360° endless rotation, 0°–90° tilting, and 45° side turning. These functions allow operators to adjust glass position and angle freely, achieving accurate alignment and fixing for every panel under complex working conditions.
With outstanding extension capability, the BVL 1000 and BVL 1500 models provide an extension distance of 897mm, while the BVL 2000 model extends up to 1200mm. This long reach enables smooth installation of glass beyond external eaves, avoiding collision and ensuring full coverage of the working area.
The BVL series adopts wireless remote control with wired backup, delivering convenient and reliable operation. This dual control system enhances operating flexibility and safety, especially for high‑altitude and long‑distance installation tasks.
Powered by a DC24V battery system (2×12V 100Ah), the machine supports up to 8 hours of continuous working time. It supports wide‑voltage charging (AC110V–240V) for global use, and features IP43 ingress protection and sound‑light alert indication to adapt to various construction site environments.
Available in three models—BVL 1000 (1000kg), BVL 1500 (1500kg), and BVL 2000 (2000kg)—the series covers a wide range of load requirements for different glass sizes and project scales. Each model is designed with optimized self‑weight to ensure stability and performance under maximum load.
For projects with overhanging eaves, the Cowest BVL series stands out as a professional installation partner. It reaches deep under eaves smoothly, keeps balance automatically during extension, achieves precise positioning, reduces labor intensity, shortens construction periods, and greatly improves on‑site safety.
By integrating auto‑balancing technology, multi‑directional electric adjustment, long extension, and strong loading capacity, the Cowest BVL Series has become the preferred choice for global curtain wall contractors, glass installation specialists, and construction machinery rental businesses. It brings higher efficiency, safety, and reliability to exterior wall glass installation, setting a new standard for facade construction under complex architectural conditions.
