Installing exterior wall glass on modern buildings with overhanging eaves has long been a tough challenge for construction and curtain wall teams. Traditional lifting tools are limited by narrow operating space, poor precision, and lack of stable balance during extension, which lowers efficiency and increases safety risks. The Cowest BVL Series Auto‑Balanced Glass Handling and Installation Machine is specially developed to solve these problems, delivering safe, efficient, and highly controllable glass installation solutions for high‑rise buildings, curtain wall projects, and structures with external eaves.
Designed with a professional auto‑balancing system, this machine keeps loads stable at any extension distance, avoiding tilt or shake during glass handling. This feature is extremely important for working in confined spaces under overhanging eaves, ensuring smooth and secure operation throughout the installation process.
The BVL series supports full‑range electric angle adjustment, including 360° endless rotation, 0°‑90° tilting, and 45° side turning. These flexible functions allow precise glass positioning even in hard‑to‑reach areas under deep eaves, meeting complex on‑site installation needs.
It offers impressive extension performance, with 897mm extension for BVL 1000 and BVL 1500 models, and up to 1200mm for the BVL 2000 model. This long reach makes it easy to install glass panels beyond external eaves without collision or interference.
Operation is simple and safe with wireless remote control, supported by wired control as a reliable backup. This dual control method improves operating distance and on‑site safety, especially for high‑altitude installation tasks.
Powered by a DC24V system with two 12V 100Ah batteries, the machine supports up to 8 hours of continuous working time. It accepts AC110V‑240V charging input, making it suitable for use in global construction sites. With IP43 ingress protection and light‑and‑acoustic alert indication, it adapts well to various outdoor working environments.
The BVL series includes three models: BVL 1000 with 1000kg maximum load capacity, BVL 1500 with 1500kg capacity, and BVL 2000 with 2000kg capacity. These models cover most standard and heavy‑duty curtain wall glass installation requirements. Each model is engineered with matched self‑weight to ensure stable performance under rated loads.
For buildings with external eaves, standard lifting booms often cannot reach target positions properly, while manual positioning is risky and inefficient. The Cowest BVL series is purpose‑built for overhanging eaves facade glass installation. It can reach deep under eaves, maintain automatic balance during horizontal extension, realize accurate angle adjustment, reduce labor input, shorten installation duration, and improve overall job‑site safety.
Combining auto‑balancing technology, multi‑angle electric control, long extension distance, and strong loading capacity, the Cowest BVL Series Auto‑Balanced Glass Installation Machine becomes the preferred equipment for curtain wall contractors, glass installation teams, and construction machinery rental companies worldwide. It sets a new benchmark for safe and efficient exterior wall glass installation, especially for projects with overhanging eaves.
