When performing high-altitude work, the platform must remain suspended at the work site for a sufficient duration. When the target location is far away, the boom also needs to provide adequate horizontal reach. This telescopic man lift can extend horizontally up to 13.2 meters. It can meet the requirements of most customers. The 21.6 m telescopic man lift is equipped with a high-capacity lithium battery, enabling prolonged continuous operation at height. The battery features an intelligent Battery Management System (BMS), which continuously monitors battery performance and provides protection during use, minimizing the impact of improper operation on the battery.
