Abstract

The invention discloses a single beam portal crane. The single beam portal crane comprises a main beam which is provided with an electric block; the two ends of the main beam are fixedly connected with landing legs, the landing legs comprise a left landing leg and a right landing leg which are fixedly connected with each other, and a grade beam is connected with the lower ends of the left landing leg and the right landing leg; the two ends of the grade beam are provided with main driven wheels which can roll along a guide rail and are externally in transmission connection with a reducer, the reducer is in transmission connection with an electromotor, and a transmission shaft between the reducer and the electromotor is provided with a brake. The single beam portal crane provided by the invention has the advantages that the whole structure is firm, the weight is light, the use is convenient and rapid, and the transmission is stable at a high speed.

Description

technical field [0001] The invention relates to the field of cranes, in particular to single beam gantry cranes. Background technique [0002] The bridge crane is a lifting device that is horizontally placed over the workshop, warehouse and stockyard for material lifting. Because its two ends are located on tall concrete pillars or metal supports, it is shaped like a bridge. The bridge frame of the bridge crane runs longitudinally along the tracks laid on the elevated sides on both sides, which can make full use of the space under the bridge frame to lift materials without being hindered by ground equipment. It is a kind of hoisting machinery with the widest range and the largest number. The existing LH type crane uses a wire rope electric hoist, and the transmission movement is often unstable. Contents of the invention [0003] The object of the present invention is to provide a single-girder gantry crane, which has a firm overall structure, light weight, convenien...
