Abstract

The invention relates to an electric hoist mono-beam bridge type crane, and relates to the field of cranes. The electric hoist mono-beam bridge type crane comprises end beams, main beams, an electric hoist running mechanism and an electrical apparatus mechanism, wherein the main beam is arranged between the end beams on both wings; the electric hoist running mechanism is arranged on the main beam and moves between the main beams under the control of the electrical apparatus mechanism; and a driving wheel set and a driven wheel set are arranged on the end beams. Due to the adoption of the novel electric hoist main beams and the novel electric hoist running mechanism and the design of a corresponding rectangular steel pipe end beam and a novel cart running mechanism, the electric hoist mono-beam bridge type crane has the advantages of reasonable structure, high manufacturability, light weight, low noise, low power consumption, long service life and accurate positioning, and is an environmental-friendly product with low energy consumption, and the weight of the complete machine can be reduced by 12 percent.

Description

technical field

[0001] The invention relates to the field of cranes, in particular to a novel electric hoist single-girder bridge crane. Background technique

[0002] Electric hoist single-girder overhead crane is a general-purpose overhead crane widely used in industrial production, warehousing, and transportation. Compared with other types of cranes of the same type, this type of crane has the characteristics of simple structure, light weight, low cost and convenient maintenance, so this type of crane is widely used in various indoor and outdoor places. Most small and medium-sized enterprises use this kind of crane, so this product is the most produced and used crane in our country. In fact, the volume is large and wide, and the annual sales volume in the country exceeds 100,000 units.

[0003] The main engine of the electric hoist single-girder bridge crane produced now is the structural type of our country in the 1970s, and the one with a small lifting capacity adopts ...
