And while we're talking wire ropes, let's talk about lay. Most detachable lifts use lang-lay wire ropes, while most fixed grips use a regular-lay. Because a regular lay has the wires of the strand laid opposite the direction of the stands upon the core, there is more resistance to grip slippage.
If anyone really wants to have some, uh, "fun" this season, study the haul ropes of different lifts as you ride. You'll notice four basic types:
Right Regular Lay (strands are laid around the core to the right, but wires are laid around the strands to the left)
Left Regular Lay (opposite above)
Right Lang Lay (strands are laid around the core to the right, and wires about the strands also laid to the right)
Left Lang Lay (opposite above)
Well, maybe that's not "fun" to all of you. But I do it............
You'll also notice most fixed grips use a 6x19 wire rope, while detachables use a 6x37. But I'm gonna quit while I'm ahead...
