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.
Claims11
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.
