- Description
28‑48m Working Height, 300‑480kg Capacity, 4WD Rough‑Terrain Straight Boom Lift for Outdoor Construction
OSEN's self-propelled diesel telescopic boom lift provides working heights from 28 m to 48 m and platform capacities from 300 kg to 480 kg. It belongs to our boom aerial work platform product line. Powered by a diesel engine for travel and lifting, it delivers strong power output and fast travel speed without relying on external power supply.
The machine is equipped with comprehensive safety protections, including multi-load range limiting, torque limiter, emergency power unit and anti-misoperation functions to fully safeguard operators during elevated work.
Our diesel telescopic boom lift adapts to harsh working environments, such as wet, corrosive, dusty, high-temperature and low-temperature sites. The unit can travel safely with the boom raised, and its travel speed automatically reduces as lifting height increases.
Long horizontal outreach, responsive operation and outstanding outdoor adaptability are the core strengths of this series. It is widely used for outdoor aerial installation, and serves as reliable equipment for shipyards, construction sites, demolition & reconstruction projects and routine maintenance teams.
