## CPC

- E02F 9/14: Booms {only for booms with cable suspension arrangements (for booms or manipulators with cable suspensions for suction pipes E02F3/905 takes precedence; for booms per se E02F3/38; E02F3/34 for bucket-arms)}; Cable suspensions
- E02F: DREDGING; SOIL-SHIFTING (winning peat E21C49/00)

## Abstract

A method and hardware for damping and controlling unwanted motion in the fixed rigging of large machines. In a first approach large clamp blocks are added to multi-cable rigging systems. These blocks use a first cable to damp the motion of an adjacent cable. The invention also encompasses adding armored sections to synthetic cables to enhance their abrasion resistance and cut resistance.

## Claims

### Claim 1

A cable stabilizing system for heavy machinery, comprising:
(a) a cab;
(b) a boom connected to said cab, said boom having a point sheave;
(c) a first stay connecting said boom to said cab, wherein said first stay supports said boom, and wherein a distal end of said first stay connects to said boom on a left side of said point sheave;
(d) a second stay connecting said boom to said cab, wherein said second stay supports said boom, and wherein a distal end of said second stay connects to said boom below said first stay and on said left side of said point sheave;
(e) a third stay connecting said boom to said cab, wherein said third stay supports said boom, and wherein a distal end of said third stay connects to said boom on a right side of said point sheave;
(f) a fourth stay connecting said boom to said cab, wherein said fourth stay supports said boom, and wherein a distal end of said fourth stay connects to said boom below said third stay and on said right side of said point sheave;
(g) a transverse clamp block connecting said first stay to said third stay, said transverse clamp block configured to damp motion between said first stay and said third stay;
(h) a first bend restrictor attached to said first stay, said first bend restrictor including first and second bend restrictor halves clamped over a first inspection region wherein said first stay's constituent strands are accessible;
(i) a second bend restrictor attached to said second stay, said second bend restrictor including first and second bend restrictor halves clamped over a second inspection region wherein said second stay's constituent strands are accessible;
(j) a third bend restrictor attached to said third stay, said third bend restrictor including first and second bend restrictor halves clamped over a third inspection region wherein said third stay's constituent strands are accessible; and
(k) a fourth bend restrictor attached to said fourth stay, said fourth bend restrictor including first and second bend restrictor halves clamped over a fourth inspection region wherein said fourth stay's constituent strands are accessible.

### Claim 2 (depends on 1)

The cable stabilizing system as recited in claim 1, wherein said transverse clamp block comprises two halves that are clamped together around said first and third stays.

### Claim 3 (depends on 1)

The cable stabilizing system as recited in claim 1, wherein said transverse clamp block is located proximate an end of said first stay.

### Claim 4 (depends on 3)

The cable stabilizing system as recited in claim 3, further comprising a second transverse clamp block connecting said second and fourth stays.

### Claim 5 (depends on 1)

The cable stabilizing system as recited in claim 1, wherein said transverse clamp block clamps over said first and third bend restrictors.

### Claim 6 (depends on 1)

The cable stabilizing system as recited in claim 1, wherein:
(a) said first transverse clamp block is clamped over said first and third bend restrictors; and
(b) said second transverse clamp block is clamped over said second and fourth bend restrictors.

### Claim 7 (depends on 1)

The cable stabilizing system as recited in claim 1, wherein said first transverse clamp block comprises two pieces that are clamped together.

### Claim 8

A cable stabilizing system for heavy machinery, comprising:
(a) a cab;
(b) a boom connected to said cab, said boom having a distal end;
(c) a first stay connecting said boom to said cab, wherein said first stay supports said boom, and wherein a distal end of said first stay connects to said distal end of said boom on a left side of said boom;
(d) a second stay connecting said boom to said cab, wherein said second stay supports said boom, and wherein a distal end of said second stay connects to said distal end of said boom below said first stay and on said left side of said boom;
(e) a third stay connecting said boom to said cab, wherein said third stay supports said boom, and wherein a distal end of said third stay connects to said distal end of said boom on a right side of said boom;
(f) a fourth stay connecting said boom to said cab, wherein said fourth stay supports said boom, and wherein a distal end of said fourth stay connects to said distal end of said boom below said third stay and on said right side of said boom;
(g) a first bend restrictor attached to said first stay, said first bend restrictor including first and second bend restrictor halves clamped over a first inspection region wherein said first stay's constituent strands are accessible;
(h) a second bend restrictor attached to said second stay, said second bend restrictor including first and second bend restrictor halves clamped over a second inspection region wherein said second stay's constituent strands are accessible;
(i) a third bend restrictor attached to said third stay, said third bend restrictor including first and second bend restrictor halves clamped over a third inspection region wherein said third stay's constituent strands are accessible;
(j) a fourth bend restrictor attached to said fourth stay, said fourth bend restrictor including first and second bend restrictor halves clamped over a fourth inspection region wherein said fourth stay's constituent strands are accessible; and
(k) a transverse clamp block located proximate said distal end of said boom connecting said first stay to said third stay by clamping over said first and third bend restrictors, said transverse clamp block configured to damp motion between said first stay and said third stay.

### Claim 9 (depends on 8)

The cable stabilizing system as recited in claim 8, wherein said transverse clamp block comprises two halves that are clamped together around said first and third stays.

### Claim 10 (depends on 8)

The cable stabilizing system as recited in claim 8, wherein said transverse clamp block is located proximate an end of said first stay.

### Claim 11 (depends on 10)

The cable stabilizing system as recited in claim 10, further comprising a second transverse clamp block connecting said second and fourth stays.
