Composite relay equipment and composite engineering machinery system

Abstract

This invention provides a composite relay device and a composite engineering machinery system for connecting engineering machinery and working attachments. The composite relay device includes a mounting platform with multiple mounting units for selectively aligning and fixing different sized base plates of a hook head seat. The hook head seat has replaceable bushings with corresponding inner diameters to accommodate corresponding shafts. Simultaneously, the attachment mounting section of the composite relay device provides different assembly interfaces for selectively assembling and driving various working attachments. Therefore, the composite relay device can adjust its docking dimensions to be compatible with machines of different tonnages, and can freely interchange various working attachments through adjustments to different assembly interfaces, thereby achieving cross-model compatibility and multi-purpose functionality.
