FIELD CABLE SUPPORT Russian patent published in 1996 - IPC

FIELD: tractional electrification of agricultural machines. SUBSTANCE: aerodynamic cable support has air screw with blade misalignment automatic device and tractional electrification air reactive electric ventilated propellers driven through planetary gear and pivotally suspended on ends of each blade for independent stabilization of tractive force by gyroscopic effect. Permanently unfolded field electric cable is fastened along its full length on double-branched puller, which is retained with its ascending branch adjacent to field transformer by shank of vertical and inclined geological harpoons submerged into foamed concrete which is further solidified. Support platform is provided with anchor submerged and fastened in vertical position. Lower end of descending branch of puller cable is attached through pivotal dielectric three-phase swivel mounted on top end of electric current collecting post of puller of electrified field agricultural machine. EFFECT: increased efficiency, wider operational capabilities and enhanced reliability in operation. 6 dwg
