Problems solved by technology

The lifting height of the existing main engine is fixed and cannot be adjusted. The extension length of the outrigger cylinder is not only the lifting height of the crane main engine
[0003] The lifting height of the main engine determines the height of the trailer used. At present, the height of an ordinary trailer is generally 1.2m, while the stretching length of an ordinary outrigger cylinder is generally about 0.8m, which cannot meet the height requirements of an ordinary cart. , therefore, for the lifting device of the existing crawler crane, only a special trailer with a relatively low height can be used, thus increasing the difficulty and cost of the trailer

Abstract

The invention relates to the technical field of vehicles and discloses a lifting device and a lifting method for a vehicle. The lifting device comprises multiple support oil cylinders, wherein each support oil cylinder is located above a mounting bracket; the lower part of each support oil cylinder is connected to the mounting bracket; the height of the mounting points of the support oil cylinders of the mounting bracket is adjustable; the cylinder bodies of the support oil cylinders are connected to the vehicle. The lifting device is applicable for lifting work of vehicles of any type which need to be trailed, and particularly applicable for lifting vehicles with relatively great weight and relatively complex structure such as a crawler crane before the vehicles are trailed; the mounting points of the support oil cylinders at a suitable height of the mounting bracket can be selected to be connected with the support oil cylinders based on the practical condition, so that the vehicle can be lifted to the ideal height required by a common trailer truck. Therefore, the cost is lowered, and the trailing difficulty is decreased.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a lifting device and a lifting method suitable for crawler cranes. Background technique [0002] Due to the heavy weight and complex structure of the existing crawler cranes during the transfer process, the transportation cost is getting higher and higher, and the transportation cost of the main engine of the crawler crane occupies a major part. The main engine is transported mainly through the outrigger cylinder to raise the main engine, and the trailer walks under the main engine to drop the main engine on the trailer, and then transports the main engine away. The lifting height of the existing main frame is fixed and cannot be adjusted, and the extension length of the outrigger oil cylinder is the lifting height of the main frame of the crane. [0003] The lifting height of the main engine determines the height of the trailer used. At present, the height of an ordinary trail...
