ISO799-2019 Marine Pilot Rope Ladder
Description:
ISO 799-2019 Marine Pilot Rope Ladder is one type of rope ladder, usually made by hard wood and used for embarking and disembarking pilots. It is a important tool for SOLAS Marine Safe Equipments. With spreaders step(Preventer Step) and magnet, pilot ladder could work safety under kinds of sea conditions.Pilot ladder with side ropes made of mildew-resistant manila or sisal rope meeting ISO1181:1990,Quality 1.
Main Technical Specification:
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 braking strength more than 24KN.
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.
Rubber Step:The bottom 4 steps may be made f 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.
Spreader:Spreader shall have the same specifications as normal steps, but length of spreader shall not be less than 1.8 meters.
Step Fixing Piece:Must be wood or plastic
Fastening Hardware:Fastening hardware for rope and steps must be corrosion resistant, or made of similar material treated corrosion resistance.
Test of ISO799-2019 Marine Pilot Rope Ladder
| Test | Item to be tested | Test procedure | Acceptance criteria |
| Visual examination | Fully assembled ladder. | Compare lo construclion requirements In Clause 4, and the manufacturer’s drawings. | The ladder shall comply with the construction requirements in Clause 4, and be constructed in accordance with the manufacturer’s drawings |
| Step flexibility | Six steps, which shall include at least one of each different type, including replacement steps,if different from steps used in the ladders onginal construction. | Place each step on a pair of Supports located where the side ropes would normally pass through the step. Apply a static load uniformly for a period of at least 1 min over a 100mm wide contact area at the centre of the step. The load shal be 3,0 kN | Deflection at the centre of the step shall not exceed 25 mm under load There shall be no residual deflection after the load isremoved and the step is allowed to recover. |
| Step fricton | One step of each different The step surface shall have One metal hook of a mass between 1.5 kg and 3.0 kg The metal block shall have a flat surface no more than 100 mm wide by 135 mm long.The flat surface shall have leather or composition shoe-sole material attached to it. | Set the reference step in a level
Repeat the procedure with the standard reference step and the block under water.
Repeat the procedure in both dry and wet conditions using each different ladder step. | The angles at which the block begins la slide on the dry and wet embarkation ladder step shal be greater than or equal to the corresponding angles measured for the standard reference step. |
| Step surface durability | One step of each different
A metal block of the type described under the step friction test arranged to enable a vertical load of 380 N to be applied to it as it slides back and forth over the step under test | secure the Step in a horizontal position, with the loaded block resting on it. Move the block back and forth from one end of the step surface to the other and back In the same line, for a total of 1500 cycles.
Repeat the step friction test on the worn step in both dry and wet
condtions,making sure the sliding block is resting completely on
the worn surface | The angles at which the block begins to slide on the dry and wet embarkation ladder step shall be greater than or equal to the corresponding angle measured for he standard reference step. |
| Ladder and step attachment strength | Fully assembled ladder of longest length e be approved | Suspend the ladder vertically, hanging to its full length or extend the ladder to its full length on a horizontal surface, with the top end of the ladder secured using its own attachments.Apply static load of 8.8 Kn widely distributed over the bottom step for a period of at least 1 min,So that the load is applied evenly between the side ropes through the step attachment fittings.Repeat the procedure at five different steps,except that the ladder is not required to be hanging at full length and only the step under test,its side rope attachments and the side rope immediately above the step attachment fittings are required to be subjected to the load | Steps shall not break or crack Attachments between any step and a side rope shall not loosen or break Side ropes shall not sustain any observable damage, elongation or deformation that ramains ater the test loads is removed |
| Unrolling | Fully assembled ladder of longest length to be approved | Attach the rolled-up ladder lo anchoring fixtures in a place away from any wall or structure that would prevent it from falling freely,and where it can hang vertically.Allow the ladder to unroll freely. | The steps and attachments shall The ladder shall not sustain damage that would make it unsafe to use. |
