摘要：
The multiple maneuvering systems for various applications includes several embodiments of wheeled, multiple maneuvering systems including multiple parallel maneuvering systems (MPMS). Each MPMS includes two or more parallel maneuvering units (PMUs) attached to one another by a connecting structure. Each PMU includes two or more powered or non-powered wheels, with the wheels being maintained parallel to one another by a steering mechanism. The steering mechanism may include gears, belt and pulley, chain and sprocket, or a rigid linkage. The connecting structure may be rigid, linearly adjustable, rotatable adjustable or both linearly and rotatable adjustable. The adjustable connecting structures allow for relative movement between the PMUs, while maintaining a load support surface(s) of the MPMSs.
