The anti-corrosion of hydraulic forklifts requires comprehensive measures from four aspects: material selection, structural design, protective measures, and daily maintenance, in order to extend the service life of the equipment and ensure safe operation. The specific methods are as follows:

1、 Material selection: Corrosion resistant materials are the foundation

stainless steel material

In acidic and alkaline environments or high humidity places (such as the food and pharmaceutical, electroplating and chemical industries), 304 stainless steel is preferred for making key components of forklifts (such as forks and frames). Stainless steel has the characteristics of corrosion resistance, oxidation resistance, and strong wear resistance, which can significantly reduce the risk of rust.

Galvanized sheet and composite materials

For ordinary industrial environments, galvanized sheet or engineering plastics (such as fiberglass) can be used to make the shell and cover. Fiberglass has good processability, strength, toughness, and plasticity, and is cost-effective. It can be used to make insulation pads for noise reduction and insulation.

2、 Structural Design: Optimizing Shape and Sealing

Smooth styling design

Drawing on the design experience of foreign forklifts, a streamlined body is adopted to reduce water accumulation and avoid the retention of corrosive substances. For example, dust covers are installed on exposed components such as tilt hydraulic cylinders and steering hydraulic cylinder piston rods to prevent dust and moisture from entering.

Sealing enhancement

The body electrical connectors are built-in, and the external connectors are equipped with protective covers.

A leakage hole is opened at the bottom of the battery box and an accumulator is installed to prevent acid from corroding the vehicle body.

Select metals with similar potential or use insulation treatment at metal joints to avoid electrochemical corrosion.

3、 Protective measures: Multi technology synergy to enhance efficiency

Coating and Electroplating Technology

The car body coating uses polyurethane, acrylic polyurethane and other paints with strong corrosion resistance to replace traditional acrylic, alkyd, and vinyl chloride coatings.

Electroplating treatment is applied to easily corroded components such as fork frames and door frame slides to form a protective layer.

Conversion film and rust proof oil

Using conversion coating technologies such as phosphating and oxidation, a chemical protective layer is formed on the metal surface.

Apply rust proof oil or grease to precision parts such as bearings and chains to form a physical isolation barrier.

4、 Daily maintenance: Details determine the anti-corrosion effect

Cleaning and fastening

Regularly clean the dirt and soil on the surface of the forklift, with a focus on cleaning the fork frame, generator, battery electrodes, and other parts.

Check the fastening of various parts (such as fork support and wheel screws) to prevent loosening and stress corrosion.

Leakage inspection and lubrication

Regularly inspect the leakage of pipe joints, fuel tanks, oil cylinders, and other parts to avoid oil corrosion of the vehicle body.

Regularly lubricate components that require lubrication, such as bearings and chains, to reduce friction and corrosion.

Seasonal protection

Rainy season: Avoid outdoor parking, clean the forklift from top to bottom after use, check and clean the moisture in the gaps.

High temperature environment: Maintain heat dissipation and ventilation of the motor to prevent high temperature from accelerating material aging.

Low temperature environment: Replace hydraulic oil suitable for low temperature to prevent system failure caused by oil solidification.

Rust treatment

After discovering rust, it should be promptly removed and cleaned, and anti rust paint should be reapplied to prevent the spread of rust.
