发明名称 Lineman's pole strap assembly
摘要 In a lineman's pole strap assembly for use on utility poles and the like, the assembly comprising an outer strap and a cross strap attached at its ends to the outer strap so as to define a closed loop encircling the pole, the cross strap is connected to the outer strap by slide members which are interconnected by an elastic tensile member under tension. In normal ascent and descent the cross strap is manually held away from the pole, but is releasable so as to be pulled into tight frictional engagement with the pole and to pull gaffs which are mounted on the slide members into listing engagement with the pole.
