Description
Technical Field

Background
The axle load requirements on the transportation vehicles are more and more strict, and the whole cargos of 200 tons in the past are usually transported by a connecting concave table transportation mode, and the axle load is seriously out of standard and forbidden due to the fact that the number of the axes of the vehicles used by the connecting concave table transportation mode cannot be too large, so that the transportation by a sedan-type transportation frame mode is replaced. In order to reduce the transportation cost and provide a good passing performance for the train, the number of train axes required in the transportation of the car type transportation frame is as small as possible on the premise that the axle load is not out of standard. For this purpose, the weight of the car-type transport frame must be as low as possible.
In order to reduce the weight of the car-type transportation frame, a plurality of middle-small car-type transportation frames (carrying 200-350 tons) are on the market at present, and a lifting device is not designed. The car-type transportation frame is special equipment for transporting undetachable large-scale cargoes such as a large-scale transformer and the like, and is generally matched with a hydraulic trailer for use. Because the goods are generally higher, the height of the goods loaded by the sedan-chair type transportation frame is limited by the heights of bridges and culverts, the height of the goods from the ground cannot be too high even after the hydraulic trailer is lifted to the highest, and the trafficability of the goods is poor. If the bottom of the goods collides with the highway guardrail of the section when entering and exiting the curve of the highway intersection, the guardrail of the section is often detached when the condition is met, and the transportation difficulty is increased.
