摘要

Disclosed is an aerial sheave device for the installation and suspension of cable. The aerial sheave device includes a frame and a rotating wheel that coordinates with a locking cable guard. The device also includes a lockable side latch for affording access to the wheel area. The frame may be attached to a utility pole via a loop attached to the frame. The loop attaches to the frame via dome-inside-a-dome connection which allows the frame to also rotate 360 degrees.
