Suspension system especially for underwater cable

1. A suspension system receiving an associated cable, the suspension system comprising:

first and second mount arms disposed in spaced relation;

a collar assembly having first and second collar members dimensioned to circumferentially enclose around the associated cable in a first assembled position, and a second open position, where the first and second collar members do not circumferentially enclose the associated cable, wherein the collar assembly receives a housing having first and second housing members adapted to receive the associated cable therethrough, and dimensioned for relative rotation between the collar assembly and the housing; and

at least one post joining the first and second mount arms together.

2. The suspension system of claim 1 wherein the first and second collar members are pivotally mounted to the first and second mount arms, respectively.

3. The suspension system of claim 1 wherein the first and second collar members are identical.

4. The suspension system of claim 1 wherein the first and second collar members include overlapping fingers having openings extending therethrough for receiving pins to circumferentially and axially join the first and second collar members together.

5. The suspension system of claim 1 wherein the collar assembly and the housing are configured to preclude relative axial movement therebetween when assembled on the associated cable.

6. The suspension system of claim 1 wherein the at least one post includes a flange at a first end welded to the first mount arm.

7. The suspension system of claim 1 wherein the at least one post has a threaded second end secured to the second mount arm via a threaded nut.

8. The suspension system of claim 1 further comprising at least one sheave assembly secured to at least one of the first and second mount arms wherein the at least one sheave assembly includes a rotatable sheave mount secured to the first and second mount arms, and configured for movement relative thereto.

9. The suspension system of claim 8 wherein the rotatable sheave mount of the at least one sheave assembly includes a generally U-shaped flange having first and second portions extending outwardly from a bight region dimensioned for receipt around a post joining the first and second mount arms together.

10. The suspension system of claim 9 further comprising a shaft extending between the first and second portions of the flange for rotatably receiving the sheave assembly thereon.

11. The suspension system of claim 10 further comprising a threaded nut received on one end of the shaft, and a retention pin received through the shaft outboard of the threaded nut to retain the nut.

12. The suspension system of claim 11 wherein the retention pin includes at least one of a flat edge to prevent rotation of the pin and a detent to limit inadvertent removal of the pin.

13. The suspension system of claim 11 wherein the at least one sheave assembly includes a first sheave assembly includes a rotatable sheave that rotates about a first axis and a second sheave assembly includes a rotatable sheave that rotates about a second axis different from the first axis.

14. A suspension system receiving an associated cable, the suspension system comprising:

first and second mount arms disposed in spaced relation:

a collar assembly having first and second collar members dimensioned to circumferentially enclose around the associated cable in a first assembled position, and a second open position, where the first and second collar members do not circumferentially enclose the associated cable;

a float attachment joined to at least one of the first and second mount arms, the float attachment configured and mounted for rotation relative to the at least one mount arm; and

at least one post joining the first and second mount arms together.

15. A suspension system receiving an associated cable, the suspension system comprising:

first and second mount arms disposed in spaced relation;

a collar assembly having first and second collar members dimensioned to circumferentially enclose around the associated cable in a first assembled position, and a second open position, where the first and second collar members do not circumferentially enclose the associated cable; and

at least one sheave assembly secured to at least one of the first and second mount arms, wherein the at least one sheave assembly includes a rotatable sheave mount secured to the first and second mount arms, and configured for movement relative thereto, and wherein the rotatable sheave mount of the at least one sheave assembly includes a generally U-shaped flange having first and second portions extending outwardly from a bight region dimensioned for receipt around a post joining the first and second mount arms together.

16. The suspension system of claim 15 wherein the at least one sheave assembly includes a sheave assembly having a rotatable sheave secured to the first and second mount arms.

17. The suspension system of claim 16 wherein the rotatable sheave is received over a post joining the first and second mount arms together.
