[0015] 2. The vertical track of the side frame is combined with the upper and lower guide wheels to constrain the lifting frame. When the hydraulic cylinder lifts the lifting column, the lifting is more stable, safe and without shaking, effectively avoiding safety hazards such as reel sliding and loosening caused by lifting;

[0016] 3. The base is guided by rails. The base drives the travel drive shaft through the travel reduction motor and the drive sprocket set. The travel drive shaft drives the active wheels to travel and transport on the rails. The rails are constrained by the rail baffles on the base, so the travel is stable, which effectively improves the safety of transportation and walking. BRIEF DESCRIPTION OF THE DRAWINGS
