Description

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.

Functional Features

High-Capacity Lithium Battery

Once aerial work begins, frequent shutdowns for recharging can disrupt personnel scheduling and delay construction progress. This telescopic man lift is equipped with a high-capacity lithium battery, enabling extended periods of continuous operation at height. It allows operators to complete more tasks within a single work cycle.

Intelligent BMS Battery Management

Stable performance of lithium batteries depends on effective management. The intelligent Battery Management System (BMS) continuously monitors and protects the battery's condition, reducing risks from improper use and ensuring reliable long-term operation.

Emergency Descent Device

Safety for aerial equipment must extend beyond normal operating conditions. In the event of unexpected power failure, this telescopic man lift features an emergency descent device that enables the platform to safely lower when power supply is interrupted.

Extended Working Reach

The straight boom design extends the working platform forward, allowing the equipment to operate without frequently approaching the target area. With greater horizontal reach, it can access high walls, steel structures, pipelines, and large-scale equipment more efficiently, minimizing repetitive vehicle repositioning and readjustments.
