STEEL CABLING
Seven-strand, left-hand lay, corrosion-resistant, utility-grade
steel cable has long been the staple of tree cabling in the US. Steel cabling is performed within tree canopies as a method of securing tree parts to one another as supplemental support to resist ice loads and wind forces, yet can provide no guarantee to save, hold togeth- er or especially reverse defective growing trends for the tree.
Common-grade cable is malleable so that it can be spliced by hand (self-wrapped around a thimble) while extra-high-strength cable (EHS) is stronger but significantly stiffer and cannot be hand- spliced. EHS is required when utilizing Rigguy wire stops. For all such connections, it is imperative that a heavy-duty thimble is used in all eye splices to reduce the chance of abrasion failure.
For anchoring cable ends, we recommend eye bolts installed com- pletely through the target branch with a washer under the nut.
We encourage arborists to closely examine the long-term goals
the customer anticipates for any cable installation and learn more about dynamic options. In other words, are customers informed that artificial restraint requires periodic inspection (as described by the ANSI A300 Annex C "Supplemental Support Systems Inspec- tion Process")?
PREFORMED LINE PRODUCTS // WEDGE GRIP
The Wedge Grip uses tension and a mechanical wedge to grip 7-strand guy wire. The Wedge Grip is made of steel instead of aluminum, and mechanically, the Wedge Grip user does not have to splay the wires apart to install but rather lays
the unaltered wire in the wedge’s channel, then the wedge is pulled into a cone-shaped steel cylinder that is said to deliver 100% of the wire’s rated tensile strength. A screw-on cap initiates
pressure to keep the wire from
slipping between loads. The Wedge
Grip consists of four parts: the outer cylinder and cap, plus two halves
of the wedge. The wedges come in
four different sizes depending on cable diameter, while the outer cylinder and cap come in one size only.
