1、 Material selection and structural design optimization

Application of corrosion-resistant materials

Priority should be given to using corrosion-resistant materials such as stainless steel, aluminum alloy, or galvanized steel to manufacture key components such as forks, frames, and hydraulic systems.

Protect metal surfaces with plastic or rubber coatings in areas exposed to corrosive media such as chemicals or humid environments.

Structural anti-corrosion design

Avoid design gaps, dead corners, or water accumulation areas to reduce the retention of corrosive media.

Optimize the drainage system to ensure that rainwater, cleaning water, etc. can be quickly discharged and avoid accumulation inside the vehicle.

2、 Surface treatment technology

coating protection

Primer+Topcoat: First apply anti rust primer (such as epoxy zinc rich primer), then cover with weather resistant topcoat (such as polyurethane paint) to form a dual protection.

Electrophoretic coating: The coating is uniformly attached to the metal surface through electrophoretic technology, suitable for complex structural components.

Powder spraying: using electrostatic spraying technology to evenly cover the surface with powder coating, and forming a dense coating after high-temperature curing.

Metal coating

Electroplating: Galvanizing and chrome plating are applied to small components such as bolts and nuts to improve their corrosion resistance.

Hot dip galvanizing: immersing the entire component in molten zinc to form a thick coating, suitable for outdoor exposed parts.

Conversion film treatment

Phosphating treatment: forms a phosphate chemical conversion film on the metal surface, enhances coating adhesion, and provides basic corrosion protection.

Passivation treatment: Chemical treatment is used to form a passivation film on the metal surface, preventing further oxidation.

3、 Environmental Control and Operating Standards

Work environment management

Humidity control: Use dehumidifiers or ventilation equipment in humid environments to keep the air dry.

Chemical isolation: Avoid forklift contact with corrosive substances such as acid, alkali, salt, etc., and set up dedicated protective areas if necessary.

Cleaning and maintenance: Clean the vehicle body promptly after operation, remove sediment and chemical residues, and prevent electrochemical corrosion.

Optimization of operational standards

Avoid scratches: During operation, prevent collisions between forks, the vehicle body, and hard objects to reduce the risk of coating damage.

Control load: Avoid overloading that may cause deformation of the frame and damage the integrity of the anti-corrosion coating.

Standardized parking: When parking for a long time, choose a dry and ventilated indoor environment to avoid outdoor exposure to sunlight or rain.

4、 Regular maintenance and upkeep

Daily inspection

Check if the coating is damaged or peeled off, and promptly repair the exposed areas.

Clean the debris in the drainage holes and gaps to prevent water accumulation and corrosion.

Check the sealing of the hydraulic and electrical systems to prevent corrosion caused by liquid leakage.

Regular maintenance

Coating repair: Conduct a comprehensive inspection of the coating every six months or one year, polish and repaint damaged areas.

Lubrication and maintenance: Regularly lubricate moving parts such as chains and bearings to reduce friction and the invasion of corrosive media.

Electrical system inspection: Check whether the insulation layer of the circuit is aging, whether the joints are loose, and prevent corrosion caused by short circuits.

Deep maintenance

Vehicle refurbishment: The forklift undergoes a comprehensive refurbishment every 3-5 years, including paint removal, rust removal, and repainting.

Component replacement: Replace severely corroded components (such as frames and forks) in a timely manner to avoid safety hazards.

5、 Special anti-corrosion measures

Corrosion prevention of hydraulic system

Use anti-wear hydraulic oil, regularly replace and filter the oil to prevent moisture and impurities from entering.

Apply rust proof oil on the surface of the hydraulic cylinder piston rod to reduce oxidation and corrosion.

Electrical system anti-corrosion

Seal electrical components to prevent the intrusion of humid air.

Use anti-corrosion terminal blocks, regularly inspect and tighten the joints.

Corrosion prevention of tires and suspension systems

Choose corrosion-resistant tires (such as rubber tires) and avoid using metal rims in corrosive environments.

Galvanize or paint the metal components of the suspension system to reduce corrosion.

6、 Personnel training and awareness enhancement

Operator training

Train operators to identify corrosion risks and master daily inspection and maintenance methods.

Emphasize the importance of standardized operations and reduce corrosion problems caused by human factors.

Maintenance personnel training

Provide anti-corrosion technology training to maintenance personnel to improve their skills in coating repair, component replacement, and other related areas.

Regularly organize anti-corrosion knowledge assessments to ensure maintenance quality.
