Ships vertical inclined ladder is used for large and medium-sized ships. When the ship is parked on the shore, it needs to rely on this movable vertical inclined ladder to move up and down. Generally, the vertical inclined ladder is made of wood or metal, which can be folded. When the ship starts to move, it can be folded automatically, and folded on the edge of the deck.

Ship vertical inclined ladder is a passage facility between the ship and the shore. For this passage facility, we must strictly control its safety performance. Like the aircraft parking garage, the connection equipment is considered to be firm and wear-resistant. Although it is not used for a long time every day, it is used for the size of each ship. For example, large ships are also used. Two vertical and inclined ladders shall be provided for peoples use, which shall be set behind the midship of the ship or near the superstructure, so as to facilitate people to get on and off the vertical and inclined ladders. The ladder mouth can be toward the tail or the head, but the straight inclined ladder shall be placed at the flat part of the outer plate of the hull after being lowered, avoiding the place where the tail line shape changes greatly as far as possible.

What is the minimum angle of use of the vertical and inclined ladder? The vertical and inclined ladder does have the minimum angle of use. Because the angle of the aluminum straight inclined ladder step is certain, the angle is too small, the contact surface between the sole surface and the step will be reduced, which is not safe. According to the height of freeboard, the difference between the general wharf and the lowest tide (about 4m) and the length of vertical inclined ladder can be removed for the minimum angle of use. The straight inclined ladder of SOLAS ii-13.9 can be used to calculate the Pythagorean theorem.

The vertical inclined ladder is very particular. There are two types of tread patterns. One is the movable vertical inclined ladder. After the angle between the vertical inclined ladder and the horizontal plane changes to a certain extent, there is a transmission rod under the step. Driven by the transmission rod, it can still maintain the horizontal state. The second is the fixed step straight inclined ladder. The step is arc-shaped. There are fixed and rotary types. The rotary type can slightly change the direction according to the horizontal direction!

The vertical inclined ladder winch is used on the ship to retract and release the working machinery and equipment in a short period of time. There are mainly three types: pneumatic, electric and manual. The equipment on the ship must be maintained regularly. Otherwise, a series of problems will be caused, such as oil leakage and overheating, which need to be paid attention to. After all, the ship must ensure the safety of the ship and the safety of personnel.

Of course, the manual and electric vertical inclined ladder winches will not cause these problems. Only the hydraulic vertical inclined ladder winches will have oil leakage and overheating. The main reason is that the position of the oil seal may be bumped on the ship for a long time, resulting in cracks and flanging. Then we need to carry out regular inspection.

The first point is the sealing degree of the oil seal position, whether there are scratches and defects. The second point is to check whether the oil return is unobstructed. The pipe diameter of the oil pipe must be guaranteed so as to make the oil return smooth. Third, because this product is used for a short time, long-term use will lead to continuous heating of the product operation part, affecting the use.
