The 3 or 5 strand rigged hoist ladder allows an operator to be hoisted, onto the conductors.
It allows an operator to move along the conductor over short distances (a few meters or feet).
The hoist ladder can be fitted to a single conductor, or to a bundle of conductors.
A wedge is used to lock the lower muffle joint, to a rigid ladder.
Maximum load of the hoist ladder assembly: 120 daN (265 lbs)
This assembly is composed of :
• Hanging system, comprising :
Two lockable swivel forks, two rollers with brake, a rigid ladder attachment pin, and an anchor point for attaching the insulated rope.
The orientation of the two forks allows the unit to be positioned on an overhead network :
- On a single conductor,
- On a bundle of conductors (400 mm / 1’3’’ or 600 mm / 2’ apart).
Maximum conductor cross-section: 1600 mm2 (3157 KCMIL)
