Products Description

Pilot ladders are core safety equipment for ship pilots to board and disembark at sea, and their stable fixation directly determines the safety of pilots and crew members.

The pilot ladders are very often unstable, under the influence of sea wind, wave vibration and hull shaking, bringing major hidden dangers to pilots transfer.

Our Pilot Ladder Yellow Magnet adopts advanced magnetic adsorption technology. The whole body is designed with high-saturation yellow warning color, which has super high visibility in fog, dark and complex sea conditions. The built-in high-strength magnet provides lasting and stable adsorption force, which can firmly fix the pilot ladder on the ship's hull steel structure. The product is optimized for marine harsh environments, with excellent waterproof, anti-rust, anti-aging and anti-corrosion performance. It is easy to install and disassemble, reusable, and suitable for all types of ocean-going vessels, cargo ships, tankers and official ships, realizing fast and safe fixing of pilot ladders in various sea operation scenarios.

Product feature

1. High Precision & Stable Performance

Adopts professional optical calibration technology, with ultra-low sight line deviation and stable measurement accuracy up to ±0.5°, effectively avoiding navigation deviation. The precision-machined scale ring ensures clear and uniform scale, no fuzzy reading, and long-term use without scale wear and failure.

2. Strict Anti-magnetic Design

The whole machine is made of customized non-magnetic materials, completely avoiding magnetic interference with the compass core. It fundamentally eliminates measurement errors caused by metal magnetization and ensures the authenticity and stability of navigation data in complex marine electromagnetic environments.

3.Marine Environmental Adaptability

With IPX7 high-level waterproof performance, it can resist seawater erosion, rainwater immersion and marine humid salt spray environment. It supports normal operation in extreme temperature of -30℃ to +60℃, and has excellent anti-corrosion, anti-rust and anti-aging properties, adapting to long-term offshore working conditions.

FAQ

Q: Is the azimuth circle universal for all marine compasses?

A: This series of azimuth circles is fully compatible with most of the marine magnetic compasses. We have multiple inner diameter specifications (165mm/246mm) to match different compass models. You can select the corresponding model according to the compass size, no modification is required, and the installation is convenient.

Q: Will the product be affected by seawater and salt spray for long-term marine use?

A: No. The product adopts non-magnetic anti-corrosion metal materials and professional salt spray resistant coating, with IPX7 waterproof grade. It has passed professional marine environmental simulation tests, and can resist seawater erosion, salt spray corrosion and humid environment, suitable for long-term offshore use.

Q: How to ensure the measurement accuracy of the instrument?

A: Each product is precisely calibrated by professional optical calibration equipment before leaving the factory, with strict control of sight line deviation and scale error. It is equipped with a level bubble to ensure horizontal measurement. Regular professional calibration every 1-2 years can maintain long-term high-precision performance.

Q: What is the operating temperature range of the product?

A: The normal operating temperature range is -30℃ to +60℃, which can adapt to extreme cold sea areas and high-temperature tropical marine environments, and can work normally in all global sea areas.

Q: What should I do if the rotation is stuck after long-term use?

A: It is usually caused by salt spray dust accumulation. Wipe the fitting gap with a clean soft cloth and add a small amount of neutral lubricating oil.
