As a professional 18 ton on-board crane and transport vehicle of Chengli brand, its core function is cargo lifting and precise transportation. It focuses on efficient heavy load and smooth operation, and is suitable for the lifting needs of light heavy objects in various scenarios such as engineering construction, logistics transportation, and municipal engineering. The dedicated device is a crane and cargo box, mainly used for lifting and transporting various types of goods. The crane has a mass of about 3695-3900kg and a maximum lifting load of 8000kg. The crane operating mechanism, hydraulic oil tank, and auxiliary hook can be selected according to the operation requirements to adapt to different lifting scenarios. The crane adopts a fully hydraulic drive mode and is equipped with dual pumps, which can achieve 360 ° full rotation operation. The operation is precise and smooth, and the lifting height and operation amplitude can be flexibly adjusted. Some models of cranes can achieve multi arm extension and contraction, with a wide range of operations. Whether it is engineering building materials, small equipment, or bulk heavy objects, they can be efficiently lifted, greatly reducing labor input and improving operation efficiency; At the same time, rear support legs can be optionally installed as needed to further enhance the stability of lifting, effectively avoiding the shaking and falling of goods during the lifting process, ensuring comprehensive safety of operations, and adapting to long-term outdoor lifting needs.
