The telescopic boom lift,It features four-wheel drive and a 45% climbing design, making it suitable for complex terrains; it is equipped with an intelligent balance system and anti-overturning protection device to ensure safe and efficient 360° full-circle operation. Electro-hydraulic proportional system control is accurate and efficient. It provides chassis tilt protection, emergency lowering, safe speed limit, comfortable start and stop technology and other protective measures.The entire machine has a compact folding structure, which is suitable for high-difficulty scenarios such as building maintenance and bridge construction, and combines flexibility with durability.
The 28-meter self-operated vertical-arm high-altitude work platform , with its high working height and large load capacity, is widely applicable to the installation of curtain walls in super high-rise buildings, steel structure construction; large ship body welding and high-altitude painting in ship manufacturing; municipal bridges – maintenance and lighting installation; power energy installation of substation equipment; large venues – advertising projects and space construction. Its 45% climbing ability and intelligent control system ensure efficient operation in complex working conditions.
