Description

Portal assembly and fork truck that coil of strip transportation was used Technical Field The application relates to the technical field of steel coil transportation, in particular to a portal frame assembly and a forklift for steel coil transportation. Background In the process of transporting the steel coil, the fork of the forklift is required to extend into the central gap area of the steel coil cylinder by means of the forward and backward movement of the forklift, so that the steel coil can be smoothly lifted and transported safely. However, this transportation mode depending on the forward and backward movement of the forklift has a certain risk, because if the operator is not skilled or attentive during the operation, the operator may cause improper movement of the forklift, and further the forklift bumps into the steel coil, which may damage the steel coil, and may pose a serious safety threat to the operator and the surrounding environment. Disclosure of utility model The utility model aims to solve the problems and provide a portal assembly for steel coil transportation and a forklift. The technical scheme of the application is realized as follows: In a first aspect, the present application provides a mast assembly for transporting steel coils, said mast assembly comprising: The portal frame is connected with the transport carrier; The mounting frame is mounted on the portal frame, and the supporting cylinder is positioned on the mounting frame; The telescopic cylinder is sleeved on the supporting cylinder in a sliding manner; The telescopic cylinder is arranged in the supporting cylinder, a cylinder barrel of the telescopic cylinder is fixed in the supporting cylinder, and a telescopic end of a telescopic rod of the telescopic cylinder is fixed with the telescopic cylinder.
