发明名称 Guy hook
摘要 A guy hook used to attach a guy cable to a transmission line pole includes an upper body portion (25), a central body portion (26), and a lower heel portion (27). The upper portion has a neck (29) and ears (28) for engaging the guy cable. The central body portion has a rearward pole-engaging surface (37), an opposite frontward side and a passageway (40) therebetween through which a through-bolt is horizontally disposed to install the hook on the pole. The frontward side includes a recess (38) surrounding the aperture (39) to the passageway for countersinking the head of a through-bolt below the frontward side to a depth substantially in line with the vertical line of action (41-42) of the hook. The moment caused by the downward and outward force exerted on the hook by the guy cable is thus minimized and therefore also the tendency of the hook to overturn and bend the through-bolt. The heel portion is vertically dimensioned to approximately 50 percent of the total height of the hook and has spurs (30-34) arranged on its pole engaging surface to maximize resistance to downslotting of the hook along the pole.
