Marine Vertical Ladder

Introduction

The straight ladder is a kind of vertical passage facility inside the ship, which is usually used in liquid tanks, empty tanks and places where some personnel do not go in and out frequently.

After completing the aerial work, it needs to be retracted in time, and the best way to place it is to place it horizontally. If it is stored vertically, the ladder may fall due to some external reasons, which may injure the staff near the ladder.

According to its manufacturing materials, straight ladders can be divided into steel ladders and aluminum ladders. According to its place of use, it can be divided into ordinary steel ladders and goods, oil ladders and so on.

AL Alloy LF5

Light weight, anti-corrosion, nice appearance but not fireproof

Q235-A

Good welding performance, Good toughness. But relatively heavy and easy to rust and corrode. After hot-dip galvanizing treatment, the anti-rust and anti-corrosion performance is greatly improved, but the surface finish is difficult to improve, which affects the appearance of the surface.

Comparison Differences

Other manufacturers low quality vertical ladder

Hi-Sea high quality vertical ladder

1. The material of the vertical ladder has a high impurity content, which is brittle, and has low strength and is easy to break. It has a short service life, and is prone to safety hazards.

2. The surface of the ladder is not properly treated, and it is easy to be rusted and damaged.

3. The ladder has not passed the load test, and there is no safety guarantee when using it.

4. The welding process of each part is poor, and it is easy to be damaged during use, affecting the service life and causing personal safety hazards.

5. The quality of the bolts, etc. is poor, and the anti-rust treatment is not carried out, which affects the service life and safety of use.

1. The gangway ladder material is made of high-quality aluminum alloy, which has high strength and light appearance, and is also corrosion-resistant and has a long service life.

2. The aluminum parts are anodized, with strong corrosion resistance, convenient maintenance and low cost.

3. Stainless steel bolts, durable structure and strong anti-corrosion ability, strong and durable ladder, low maintenance cost.

4. After passing the inspection of classification society, CCS, ABS, BV and other classification society certificates can be issued, and the quality is guaranteed.

5. Meet ISO standard.
