Rust prevention is critical for pneumatic monorail cranes, especially in humid, industrial environments. Below is a structured approach to protect your equipment:

1. Material Selection

Stainless Steel/Aluminum

Use corrosion-resistant alloys for critical components (e.g., load hooks, trolleys) in wet/chemical environments.

Galvanized Steel

Hot-dip galvanized structural beams and tracks for long-term protection.

2. Surface Coatings

Epoxy/Polyurethane Paint

Apply high-durability coatings to metal surfaces (ISO 12944-C5+ rated for harsh industrial zones).

Zinc-Rich Primers

Use sacrificial zinc coatings on welded joints or damaged areas.

3. Pneumatic System Protection

Air Quality Control

Install desiccant dryers (dew point ≤ -40°C) to eliminate moisture.

Add oil-water separators and particulate filters (ISO 8573-1 Class 1.4.1).

Lubrication

Use anti-corrosion pneumatic oils (e.g., ISO VG32 with rust inhibitors) in cylinders/valves.

4. Environmental Mitigation

Ventilation

Install fans/exhaust systems to reduce humidity in enclosed areas.

Sealing

Use rubber gaskets/neoprene seals around control panels and junction boxes.

5. Active Maintenance

Cleaning Schedule

Daily: Wipe down surfaces with a dry cloth.

Weekly: Remove salt/chemical residues with mild detergent (pH 6–8).

Inspection

Check for paint chips, condensation, or white rust (zinc oxide) on galvanized parts.

6. Advanced Solutions

Cathodic Protection

For outdoor tracks, use sacrificial anodes (zinc/magnesium) bonded to steel.

Vapor Phase Inhibitors (VPI)

Install corrosion-inhibiting emitters in enclosed pneumatic cabinets.

7. Component-Specific Care

Chains/Cables

Coat with wax-based lubricants or use stainless steel variants.

Pneumatic Hoses

Replace rubber hoses with nylon/polyurethane tubing resistant to moisture absorption.

8. Monitoring & Testing

Humidity Sensors

Deploy in high-risk zones (e.g., near washdown areas).

Thickness Gauges

Measure paint/galvanizing thickness annually (target: >80% original thickness).

Industry Standards Compliance:

Adhere to ISO 12944 for corrosion protection of steel structures.

Follow NFPA 70 (NEC) for electrical enclosure sealing in wet environments.
