What is Ladder Fender?
A ladder fender, also known as a boarding ladder or gangway fender, is a device used on boats and ships to facilitate safe and easy access between the vessel and a dock, pier, or another structure.
Mountains V Type Rubber Fenders usually use at ports and docks on quay walls and other berthing structures. They absorb the kinetic energy of a berthing vessel and thus prevent damage to the vessel or the berthing structure.
D Type fenders are the commonly used rubber bumpers across the world and they are produced by means of extrusion in an extensive range of designs and sizes.
Roller type rubber fender is designed to guild the ships in restricted spaces like dock, roll-on roll-off terminal or other circumstance in which limit the ship deviation.

The Corner Rubber Fender is commonly used for exposed corners or edges to decrease the vessel damages during approaching the corners or coming to the berths.
Unit Element Fender which is also called element fender or leg fender is a high performance, modular system. Leg fender has been widly used across the world for decades.
D Type fenders are the commonly used rubber bumpers across the world and they are produced by means of extrusion in an extensive range of designs and sizes.
Tug Boat Rubber Fender are the commonly used on the bow and stern of tugs as primary pushing fenders.
Mountains Super High Reaction Force Super Cell Rubber Fenders for dock with PE Front Panels are mostly installed for docks (Dock medium type to VLCC) where reaction force is an important criteria.
Shanghai Mountains Cone rubber fenders are an improved version of Cell type Fender recently introduced and recommended for all type of applications including high tidal variation sites.
Protects from collision
When the boat reaches the dock, a lot of material is loaded, and supplies are transferred. It can sometimes become dangerous because accidents and collisions might happen during this process. The marine Ladder Fender protects the hull from colliding with other vessels, thus ensuring safety while transferring the goods.
Ease of Use
Ladder fenders are designed to be user-friendly, allowing individuals to quickly and easily climb from the water level up to the deck or vice versa. This is especially beneficial for passengers and crew who may need to board or disembark frequently.
Helps in tilt berthing
During the berthing process, the boat gets tilted, and a lot of pressure is put on it. The typical Ladder Fender absorbs energy and reduces the chances of accidents.
Advantages during crucial weather conditions
In critical weather conditions, the wave action is serious, and the mooring process becomes more complicated due to the imbalance between the upper and lower terminals. This imposes a high shear force on the fender, and frequent changes in force during mooring in such weather conditions will cause fatigue on a typical solid fender. However, on the other hand, the flexible contact area and larger allowable deflection characteristics of the aero fender can minimize fatigue in this case. In fact, for severe seas or frequent severe weather conditions, pneumatic fenders may be better than solid fenders because of their longer service life.
Versatility
Ladder fenders are versatile and can be used on a variety of boats, from small pleasure craft to large commercial ships. They are also suitable for both saltwater and freshwater environments.
Deterioration in performance minimized
Aging and fatigue often lead to degraded fender performance. However, due to its air-filled body and highly elastic materials, such problems are minimized. Solid rubber fenders or foam fenders depend more on the hardness of the material, and this dependence may lead to a decline in energy absorption performance after years of use and temperature changes. On the other hand, as long as basic maintenance and air pressure control are maintained, the pneumatic fender can maintain its best performance even at extremely low temperatures as low as -50 degrees Celsius or during periods of high fluctuations.
How to select the boat Ladder Fender?
Size of the boat
Before selecting the boat fender, you should consider the size and weight of the boat. The bigger the boat is, the more funding you require; smaller boats require less fending, whereas those boats whose size is more than 40 feet require more fending.
Heavy/Light
If the boat is heavy or is loaded with cargo, you need more force to stop it. Therefore to avoid sudden shock and impact when docking, you should consider selecting the heavy boat fender. After all, who wants to install an unsuitable fender that causes a large amount of damage?
Mooring condition
Colliding is an unfortunate incident you can't avoid at the dock, but with the fenders, there are chances of less damage. When selecting the fender, consider the mooring conditions for docking the boat. Think about whether you will moor the boat against the fixed object.
The looks
If the boat is commercial or used for frequent boating, it is susceptible to collision. Hence the aesthetics of the fender becomes the last point to consider. If you own a leisure yacht or holiday boat, you might not want to put an ugly fender on. So, depending on your boat type and need, you can consider installing the boat fender.
Do you want to hang it horizontally or vertically
There are some fenders you can hang horizontally and others that you hang vertically using one-line centering. You can choose according to your requirements.
The marine gangway is a device on the ship to facilitate people to board or leave the ship. It is an important channel connecting the ship's side with the shore or other ships, and has important safety and practicality. The basic principle of the marine gangway is to use the structure of the ladder and the principle of gravity to enable people to enter and exit the ship safely and conveniently. The gangway is generally composed of a ladder body, a bracket, a handrail and a footrest.
The ladder body of the marine gangway is usually made of metal materials, such as steel or aluminum alloy. This material has good corrosion resistance and strength, and can withstand the weight of people and the influence of the external environment. The design of the ladder usually adopts a certain angle to provide a better boarding experience and comfort.
The bracket of the gangway is the part that connects the ladder to the ship's side or the shore. The bracket is usually made of metal materials, such as steel or aluminum alloy, to ensure its stability and durability. The design of the bracket needs to take into account factors such as the distance and height difference between the gangway and the ship or the shore, as well as the structure and shape of the hull.
The handrail of the gangway is used to ensure the safety of people during boarding or leaving the ship. Handrails are usually located on both sides of the ladder to provide additional support and stability. The design of the handrails usually adopts a curved shape so that people can hold it firmly. In addition, the height and position of the handrails also need to be reasonably designed according to ergonomic principles to provide the best use experience.
The footrest of the gangway is used to facilitate people to board or leave the ship. The footrest is usually located on each step of the ladder to provide additional support and stability. The design of the footrest is usually made of non-slip material to prevent people from slipping or falling during use.
The use of the marine gangway is relatively simple. When the ship is close to the shore or other ships, the gangway can be placed on the side of the ship and fixed by a bracket. People can walk up the gangway from the shore or other ships as needed, and gradually board the ship through the handrails and footrests. Similarly, when people need to leave the ship, they can gradually leave along the gangway and finally walk to the shore or other ships.
The marine gangway plays a vital role on the ship. It not only facilitates the entry and exit of people, but also provides safety. The structure and design of the gangway need to be strictly tested and verified to ensure its reliability and durability. In addition, the installation and maintenance of the gangway also need to be carried out in accordance with relevant standards and specifications to ensure its normal operation and use.
The marine gangway is an important ship device that allows people to enter and exit the ship safely and conveniently by utilizing the structure and gravity principle of the ladder.

The installation and maintenance of the gangway also need to be carried out in accordance with relevant standards and specifications to ensure its reliability and durability. With the marine gangway, people can better enjoy the convenience and comfort brought by the ship.
Step 1: Start by covering the area with masking tape. This will provide a better surface to draw on and to help prevent scratching the transom, cover the area with masking tape.
Step 2: When it comes to choosing a spot on the transom for the ladder to go, make sure it is far enough to the port or starboard side that the ladder doesn't interfere with the turning of the motor whether it is tilted up or down. Now draw a vertical line down the transom to mark the edge of the ladder and then a horizontal line where the waterline usually sits when the boat is at rest.
Step 3: Check there are no wires or supports on the other side of the transom and enough room to accommodate the backing board. If not, you may need to swap sides of the transom.
Step 4: To determine the height of the ladder, hold it up along the vertical line and mark the top of the mounting bolt ensuring the bottom two rungs of the ladder are below the waterline to make it easier for swimmers to exit the water.
Step 5: Using the mounting plate as a template, mark the mounting hole locations. Recheck the position of the ladder before drilling any holes.
Step 6: Drill the holes and bolt on the bracket with sealant between the bracket and transom. Tighten bolts and wipe off any excess sealant. Once completely dry, attach the ladder.
When lowering the gangway, after the 'STOP' button was released, the gangway would continue to fall for a distance before stopping;
When the gangway is withdrawn, the output shaft of the gear box is weak, slow or even unable to be withdrawn, which requires the hand hoist assistance.
The oil level mirror of the gear case is covered with paint or blurred, the oil is deteriorated, and the gear case oil cannot be replaced timely due to negligence or no regular inspection on board. The oil oxidation/emulsification phenomenon is serious, resulting in corrosion and wear of the internal components. The bottom seat of the gear box is seriously corroded, and rust removal and paint maintenance are not carried out regularly.
The gangway wire was not inspected and maintained as required, with wire strand broke, missing grease and guide wheel stuck.
After berthing, the axle pin under the upper platform was found seriously corroded and stuck without grease, and the pin was pulled off;
Gangway was unable to be put down after berthing. Electric motor burns out while lowering the gangway;
During docking, the watchman did not adjust the gangway in time. Due to the wave effect of the passing ship, own ship' shaking or moving resulted in the gangway being clipped and deformed.
Operation Of Ladder Fender
Maintenance of gangway shall be strictly observed if specified by the manager or PMS. If there is no explicitly request, maintenance records shall be established on board, and included in the Chief Officer handover notes;
The gangway function test should be carried out 1-2 days before the ship arrival to avoid the delay of the arrival due to the failure of the gangway, which many cases related. Necessary protective measures should be taken during testing, such as protective steel wire or block, to avoid sudden slide of gangway;
For the gangway driven by electric motor, the engine department should also be informed of the insulation test before arrival, and the power can only be provided after the test is qualified. Many cases of water dampened motor leading to the burning without test first. All limit protection devices should be checked for effectiveness as well;
A self-lighted life buoy and buoyancy life line should be available near the gangway for immediate use during berthing;
The watchman should adjust the height of the bottom plat from time to time according to the change of tide and the loading and unloading situation, so as to prevent the damage due to shifting and crashing by the influence of other ships. Pay attention to the working conditions of the gangway, if any problems are found to solve in time, so as not to cause more accidents;
If no on/ off at anchorage, the gangway should be raised to horizontal position to avoid illegal entry.
