摘要

The system has a mechanically welded beam frame (5) supported by back wheels (6), and front wheels (7) articulated on the frame at an axle (9). A hitch tongue (1) mounted on the frame is articulated on another axle, and a countershaft (2) is articulated on an axle (4) of the frame and connected to the tongue by helical and sliding pivot connection. An upper link (10) connects the wheels (7) with the hitch tongue.
