Abstract
A single bolt deadend anchor clamp for gripping a cable includes a body having a clevis assembly at a first end and a sagging eye at an opposing second end. A middle body extends between the first and second ends, and includes a reinforcing rib. A pocket is adjacent the reinforcing rib for receiving a keeper inserted above the pocket. A biasing member is disposed between the pocket and the keeper for counterbalancing a load between the keeper and the retaining groove. The biasing member is preferably a spring including a cross bar and two sets of coils.
Claims14
A wedge clamp comprising:
- a body having a clevis assembly at a first end and an eye at an opposing second end;
- a middle body extending between said first and second ends, including a reinforcing rib protruding laterally from said middle body extending continuously and longitudinally from said clevis to said eye;
- a pocket in said body adjacent but laterally spaced from said reinforcing rib receiving a keeper inserted above said pocket, said pocket being a shallow cavity with first and second supports on opposite ends of said pocket,
- said keeper including a nested surface facing a middle of said keeper and being received between first and second supports, said nested surface having an edge with angularly oriented planar surfaces for receiving a nut;
- a retaining groove having a substantially V-shaped surface disposed adjacent said pocket corresponding to a bottom surface of said keeper;
- and
- a biasing member disposed between said pocket and said keeper for counterbalancing a load between said keeper and said retaining groove.
