The main materials of manual forklifts involve multiple key components, which are detailed below from the aspects of structural support, hydraulic system, load-bearing components, wheels, and additional functional materials

1、 Structural support material: high-strength steel

Q235 carbon structural steel

Application: Widely used in basic structures such as frames and forks, due to its excellent welding performance and low cost, it is suitable for large-scale production.

Characteristics: The yield strength is about 235MPa, and it is rust resistant through surface treatment such as painting and coating, meeting the basic bearing requirements.

Case: Ordinary 2-3 ton manual forklifts often use 4mm thick Q235 steel plates for their forks to ensure bending strength.

Q345 low-alloy steel

Application: High end models (such as the Junhengli AMX I15 series) are used to enhance structural strength and adapt to higher loads.

Features: Yield strength increased by 40% compared to Q235, stronger impact resistance, suitable for heavy-duty or high-frequency use scenarios.

National standard I-beam No. 12

Application: The columns of some forklift models (such as 2-ton I-beam manual forklifts) are used to improve lifting stability.

Features: Large sectional moment of inertia, high bending stiffness, supporting a lifting height of 1.6 meters.

2、 Hydraulic system materials: sealing and pressure resistant design

Integrated casting pump

Application: Replace traditional steel plate welding pumps to reduce the risk of oil leakage.

Features: The upper and lower layers of the structure are isolated by piston rods and sealing rings, which can still prevent leakage when the pressure cylinder seal is damaged.

Case: The Junhengli AMX I15 series uses this type of pump body and supports a single pump pressure to complete the full stroke lifting and lowering of the fork.

H1/H2 grade food grade lubricants

Application: Used in hydraulic pipelines for direct contact scenarios in food processing workshops.

Characteristics: Non toxic, corrosion-resistant, in compliance with EU sanitary equipment standards.

3、 Bearing component material: wear-resistant and corrosion-resistant

Stainless steel chassis

Application: Pharmaceutical, food processing and other industries (such as the Junhengli AMX I15 series).

Characteristics: Acid resistant, salt resistant, high humidity resistant, special cavity structure to avoid residual pollutants.

Polyurethane tires

Application: Scenes with smooth ground conditions or requiring anti-static measures.

Features: Wear resistant, tear resistant, with better load-bearing stability than nylon wheels, avoiding the risk of pneumatic tire blowouts.

Comparison: Nylon wheels have low cost but are prone to scratching the ground, while aluminum alloy and polyurethane wheels are suitable for harsh surfaces.

4、 Wheel material: Suitable for different ground conditions

nylon wheel

Application: Smooth ground (such as warehouse cement floor), low cost and labor-saving.

Limitations: High hardness, easy to scratch the floor.

Polyurethane wheels

Application: Floor or quiet scenes (such as retail stores).

Features: Good elasticity, strong shock absorption, and reduced rolling resistance.

Aluminum alloy with polyurethane wheels

Application: Rough surfaces (such as gravel roads), balancing wear resistance and load-bearing capacity.

5、 Additional functional materials: Safety and hygiene design

Closed fork tip

Application: To prevent homework debris from splashing (such as the Junhengli AMX I15 series).

Features: Integrated protection device for fork rollers to prevent wear on the pallet contact surface.

IP54 protection level waterproof joint

Application: Circuit system to prevent liquid intrusion from causing short circuits.

Case: The AMX I15 series supports stable operation in humid environments.

Galvanized moisture-proof hydraulic cylinder

Application: Prevent rusting of hydraulic systems and extend their service life.
