Description

Technical Field

[0001] The utility model relates to the technical field of automobiles, and in particular to a hook fixing device for an automobile crane. Background Art

[0002] Currently, the end of the telescopic boom of existing truck cranes is designed to extend two meters beyond the head of the vehicle to facilitate lifting operations. After the crane completes the lifting operation, the lifting rope on the telescopic boom needs to be retracted and the boom retracted and leveled. To ensure that the hook located below the front end of the telescopic boom does not swing significantly during driving, it is usually tightened toward the front of the vehicle with a rope and secured to the front of the vehicle.

[0003] After searching, the Chinese patent authorization announcement number CN104935003B, announcement date December 11, 2018, discloses a hook fixing device for a car crane. The article proposes "fixing parts and connecting parts, the fixing parts include a base and a limit block, two limit blocks are symmetrically fixed on the upper end of the base, and a limit groove is provided between the limit blocks." When the device fixes the hook, it is necessary to manually push the hook to hook the steel cable ring, which increases manual labor and working time. The welding mechanism is fixed and its tilt angle cannot be easily adjusted, which reduces welding efficiency. In view of this, in-depth research was conducted on the above problems, and this case was created. Utility Model Content
