It is widely used in production processes like automobile painting, general assembly, welding, etc. and many other ground conveying systems. It is mainly composed of roller bed, movable roller bed, rotatable roller bed, lifting roller bed, roller bed lifter, positioner, etc.
The skid conveying system is originated from and widely used in European and American automotive manufacturing industry. The application of the automotive manufacturing industry in German, America, France, and other countries also correspondingly form a main application system of Germany system, American system, French system, etc.
The skid conveying system has a large-scale application in the welding, coating and general assembly of the automobile manufacturing industry and the corridor between them. Especially since 2000, most coating ground conveying method has adopted this conveying system.
With the development of industrial modernization, requirements for automatic conveyors are becoming more and more. In industries such as the automobile manufacturing industry, some ground flexible conveying systems are often needed to improve the modernization degree of the manufacturing process. The application of the skid conveyor to production processes of automobile manufacturing such as painting, general assembly, welding assembly, etc. can meet some specific requirements of the automobile industry. Its characteristics and advantages cannot be replaced by board conveyors and power and free chain conveyors.
