Description

Technical Field

[0001] The utility model relates to a movable hydraulic spare tire rack device, belonging to the technical field of automobile spare tire racks. Background Art

[0002] As an important modern industrial product, automobiles are of great help to people. However, tire wear is inevitable during driving, so cars are equipped with spare tires and spare tire racks for spare tires. At present, the spare tire fixing methods of vehicles are mainly divided into lower-mounted and rear-mounted types, which are not very convenient to operate. For vehicles with higher chassis such as special-purpose vehicles or special vehicles, due to limited chassis space, the spare tire rack is generally placed at the connection between the front of the cab and the car body. The spare tire rack is high from the ground and cannot move horizontally. It cannot be accurately positioned during installation, which is inconvenient to install. Due to cost constraints, most of these spare tire racks use wire rope reels to achieve lifting and lowering. The efficiency of the spare tire rack is low, so the operation time is long when replacing the spare tire. During the operation, personnel need to manually flip up the spare tire, which is extremely inconvenient to use. Summary of the invention
