Description

Technical Field

[0001] The utility model relates to the technical field of cranes, in particular to a truck-mounted crane with good fixability. Background Art

[0002] Cranes are a type of lifting and handling machinery widely used in ports, workshops, power plants, construction sites, and other areas. The term "crane" is a general term for lifting machinery. Cranes are primarily truck cranes, crawler cranes, and tire cranes. Cranes are used for lifting equipment, emergency rescue, lifting machinery, and rescue operations.

[0003] There are many ways to install a truck crane. Some truck cranes are directly mounted on the beams of the vehicle, while others are installed inside the vehicle compartment. For the crane installed inside the compartment, the crane base is connected to the compartment by bolts. Since it is usually installed at one end of the vehicle compartment, during long-term use, one end of the crane base will become concave due to long-term stress, causing the entire crane to tilt, thereby affecting the stability of the crane installation. For this reason, a truck crane with good fixation is proposed. Utility Model Content
