1. Pilot Ladder & Embarkation In the manufacture of Ladder, due to the deterioration of the rope, the strength of the Ladder is lower than that of the original rope ladder.

2. Pilot Ladder & Embarkation using metal In the process of manufacturing Ladder, the complexity of process and wear on the ground plane of metal and rope are caused.

3. When the assembly is made under the condition that the tensile force is not constant due to the characteristics of the rope, when the finished product is finished, the product is distorted and an imbalance between right and left balance occurs.

1. When producing Pilot Ladder & Embarkation Ladder, take into consideration the deformation of the ropes afterwards and make mechanical deformation through hydraulic device. Then, manufacture Pilot Ladder & Embarkation Ladder.

2. Pilot Ladder & Embarkation Ladder using metal Self-manufactured clamps are used during manufacturing to simplify the process and prevent wear at the ground points between ropes and metal clamps.

3. Use the spring to create the same tensile force on the rope when manufacturing the Pilot Ladder & Embarkation Ladder. A rope is applied to the rope with the same tensile force to maintain the tensile force.

1. Manufacturing method using hydraulic press device

Pilot Ladder & Embarkation Ladder can be manufactured to create a Pilot Ladder & Embarkation Ladder that can withstand a constant force without deforming the rope even if time passes by using a hydraulic press device in consideration of subsequent rope deformation.

2. Manufacturing method using clamp

Simplify the process using self-developed clamps in the manufacture of Pilot Ladder & Embarkation Ladder using metal 롸 Manufacturing method to prevent abrasion phenomenon at the ground point between rope and metal clamp

3. Manufacturing method using spring

Pilot Ladder & Embarkation When producing Ladder, use the spring to generate the same tensile force on the rope.

A rope is applied to the rope with the same tensile force to maintain the tensile force. Pilot Ladder & Embarkation When the Ladder product is finished, it is manufactured to receive the same tensile force between the ropes so that no warping or horizontal imbalance occurs.

The present invention will now be described in detail with reference to the accompanying drawings.

1. Manufacturing method using a hydraulic device [Fig. 1-A]

It is a manufacturing method that is used to make rope ladders that are installed to go up and down ships. Rope ladders made using bundle strings will cause deformation of the ropes over time (A_1).

Due to the deformation of the rope, the strength of the string decreases over time than the original string strength, which naturally results in less strength than the initial production of the rope ladder.

In order to prevent this phenomenon in advance, it is anticipated that the deformation will occur in the future, and the deformation of the rope is preferentially applied during assembly through the hydraulic device (_2) to remove the space generated between the ropes (a_3). .

The rope ladder made through such a process does not reduce the strength of the bundle rope even after a time, and a rope ladder is formed in which deformation of the rope does not proceed (_4).

2. Manufacturing method using clamp [Fig. 2 Figure-B]

It is a manufacturing method that is used to make rope ladders that are installed to go up and down ships. When manufacturing a rope ladder using metal, there is a difficulty in manufacturing due to the complexity of the process. To solve this difficulty, the clamp (B_1) was devised.

The clamps are assembled using mechanical hydraulics, and the ends of the clamps are rounded (b_2) to prevent wear from occurring in contact with the rope.

When assembling, it is fixed by vice and then using the hydraulic device to prevent the occurrence of space between the ropes in advance (B_3) and then fix the produced clamp through the mechanical hydraulic device (B_4).

The rope ladder thus manufactured will maintain safety without damage or deformation over time.

3. Manufacturing method using spring

It is a manufacturing method that is used to make rope ladders that are installed to go up and down ships. The manila rope used in the product has a difference in the length of the rope when a difference in tensile force occurs due to the characteristics of the rope.

Since the rope ladder is a product in which four ropes support the scaffold, when the four ropes are produced in the same length, the horizontal state and the distortion of the product do not occur.

To prevent this phenomenon, the same tension is generated on the four ropes using the spring (_1) (3).

Ropes that received the same tensile force would use a vise (da_3) to maintain a constant tension (da_4).

The rope ladder, made of springs and vices, eliminates torsion and keeps level.
