Description

Technical Field

[0001] The utility model relates to the technical field of RGV power vehicles, in particular to a high-load and low-height RGV power vehicle. Background Art

[0002] An RGV vehicle is a vehicle that uses guide rails to limit its movement. This type of vehicle is generally equipped with rail wheels that match the rails, and the rotation of the rail wheels allows the RGV vehicle to move back and forth in a certain direction along the rails. The disadvantage of existing RGV vehicles is that, because they need to carry some large parts, they are configured for high load capacity. However, the corresponding frame height is set high, and the corresponding power unit is set below the frame, which results in a high vehicle height, making it difficult to load or unload large parts. A lot of research has been done on this. Utility Model Content
