1. Side Rope
Ropes should be mold-resistant manila or heat-treated polyester rope with polypropylene core and should not be covered. Ropes shall be of a diameter which is no less than 57mm in circumference, and have a breaking strength more than 24KN.
2. Steps
The distance of inner edge of side ropes should be more than 400mm. The width of step is no less than 115mm, and thickness no less than 25mm. The steps should be non-slip, hard wood steps without knot and equally spaced at 330±20mm。
3.The Last 4 Steps
The bottom 4 steps may be made of resilient synthetic raw material or rubber if it is of sufficient strength and stiffness. Rubber steps should be of the same required dimensions as the wooden steps.
4. Preventer Step(Spreader)
Preventer Step shall have the same specifications as normal steps, but the length of preventer steps shall not be less than 1.8 meter. The 5th step from bottom step must be preventer step, and there are maximum 9steps between preventer steps
5. Replaement Steps
Repairs to pilot ladder shall be made to the steps and preventer steps only. The repaired steps and preventer steps shall have the form and dimensions specified in item(2) and (4), and not more than 2 such steps shall be used in any pilot ladder. Repaired steps and Preventer steps shall be replaced by new ones ASAP.
6. Step Fixing Piece(Split Distance)
Step fixing piece must be made of wood or plastic
7. Fastening Hardware
Fastening hardware for rope and steps must be corrosion resistant, or made of similar material treated corrosion resistance.

Approval Standard:
