Preferably, the hook is provided with a locking member for closing the hook opening; the locking piece rotates to be connected in the one end of lifting hook coupler body, and when the lock is locked, the lock is at the other end of lifting hook coupler body. With this structure, the connection ring is prevented from being detached from the hook.
Preferably, the horizontal cross bar and the vehicle support penetrate through the longitudinal steel pipe in the middle of the support in the cross direction, the joint is fixedly welded, and in addition, two sides of the horizontal cross bar are respectively welded and reinforced by the two steel pipes and the longitudinal steel pipe in the middle of the vehicle support to form a stable triangular structure. After adopting this kind of structure, increased the stability of horizontal pole and car support.
Preferably, when the pipeline material loaded by the lifting truck is static, one end of the pipeline material is grounded to provide a fulcrum for the lifting truck, so that the lifting truck is ensured to be in a stable and non-falling state; when the hoisting truck loads the pipeline material to move, downward pressure is applied to the other end of the pipeline material, and traction force is applied to the other end of the pipeline material to enable the hoisting truck to move. After adopting this kind of structure, guaranteed the stable not fall down state when lifting by crane the carrier static.
Compared with the prior art, the invention has the advantages that: the invention can be used for transporting pipeline stone materials, pipeline steel materials or wood materials, has good adaptability to the size of the transported object, and has stable object loading and good safety during transportation.
