The main structure of a wheeled excavator consists of the working device, cab, slewing mechanism, power unit, transmission control mechanism, chassis, and auxiliary equipment. The cab, power unit, and auxiliary equipment are all mounted on a fully slewing platform, commonly known as the upper turntable. The wheeled chassis consists of the frame, support structure, gearbox, hydraulic motor, front and rear axles, tires, and is assembled with the slewing mechanism. The working device primarily comprises the boom, arm, bucket, and connecting rod. Buckets are available in various types, depending on their operating mode, such as front shovel, backhoe, dragline, and grab shovel. Booms primarily include gooseneck integral bending and hydraulically operated split multi-section booms. Multi-section backhoe booms are widely used in similar products abroad.
