As a Dongfeng brand 25 ton professional truck mounted crane and transport vehicle, its core function is cargo lifting and precise transportation. It focuses on efficient heavy loading and smooth operation, and is suitable for heavy lifting needs 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 can flexibly choose from multiple brands and models, covering well-known manufacturers such as XCMG, Sany, Renesas, Haotian, etc. It can choose SQS300, SQS250, SPS30000 and other models, with a maximum lifting load of up to 12000kg. The weight of the crane varies from 4200-6300kg depending on the model number. Some models of cranes can achieve four arm extension and contraction, and the maximum working range can reach 14.5kg. M, with a maximum amplitude of 75 °, can achieve 360 ° rotation operation, suitable for lifting heavy objects of different sizes and weights. The crane adopts hydraulic drive mode and is equipped with dual pumps, with precise and smooth operation. It can flexibly adjust the lifting height and amplitude. Whether it is large engineering equipment, building materials, or bulk heavy objects, it can efficiently complete lifting, greatly reducing labor input and improving operational efficiency; At the same time, the inner side of the frame at the installation site of the crane has been reinforced and equipped with dual chamber or single chamber hydraulic rear support legs. The full span of the support legs can reach 6.1m, with excellent stability, which can effectively avoid the shaking and falling of goods during the lifting process and ensure the safety of the operation in all aspects.
